[Text] Abstract
This collection EARTHQUAKES IN THE USSR IN 1974 includes articles with a
description of the instrument and macroseismic data on earthquakes of
various aeismically active zones (Carpathia, Crimea, The Caucasus,
Kopetdag, Central Asia, NorChern Tyan'-Shan', Altay-Sayany, Baykal,
Yakutiya, the Northeast Qf the USSR, Che Arctic, Sakhalin, the Kuril
Islands, Kamchatka) located in the territory of the USSR and bordering
_ regions. All of the articles contain earthquake catalogs and maps of the
epicenters. There are also articles with A brief survey of the seismicity
- of the territory of the USSR with respect to earthquakes with tt;4.5 and
the world with Ma6. _
The most noteworthy seismic events this year occurred in the Caucasus.
, They include four earthquakes: the 7-point Kilyatlinskiye and Salatauakoye
in Ua~estan accompanied by foreshocks and aftershocks; the Bezhtinskoye
earthquake of the same strength in the vicinity of the Dzhavakhetskiy
Island, at the bo rd er of the Armenian SSR and the Georgian SSR, and
- force 6-7, the Shakhnazarskoye, at the bo rd er of Georgia and Dagestan.
The collection ts intended for a broad class of seismologists, including
speciaiists in the field of earthquake-resistant construction and engineer-
_ ing seismology. It is of interest for geophysicists and geologists
studying the tecto n ic processes in seismically active zones.
Foreword
~ The greater part of the territory of the USSR, especially its southern
and eastern edges, is sub3ect to earthquakes. More than 200 stationary
seismic stations record these earthquakes in order to obtain obaervation

deep sCruceure of the earth xnd also the precursors of sCrong e~rth-
- quakee.
.
After primary processing nnd generalization with re~pect to individt~nl
large r.eg~.ons, this materi~l ie published annually in the Articles af Chis
collection. Tt~e arCicles contain a brief analysis of the s~?ismic activiCy for
ttie year ancl are accompanied by an earthquake catalog, the epicenter map -
and rhe macroseismic information.
The ~arthquxke catalogs compiled in the fnrm of Che EARTH4i3~.r~ ATLAS OF
THE USSR contain the followin~: the time of occurrence of the earthquake
(Greenwich mean time), the coordinates of the epicenter (in tentha and
hundredths oE a degree), the depCh of center (without parentheses, b y
the instrumecit dnta and in parenCheses, by the macroseismic
data), the accuracy class (A the errors do not exceed 25 km,
B-- the same at 50 km, A-~ the same at 5 km, S-- the same at 10 km;
if the graph is not satisfied, the error can be more than 50 km).
The parameters of a11 of the earthquakes in the regional cataloga are
determined by the data of the experimental structures. Frequently the
network of regional stations turns out to be located very one-sidedly at
the epicenCer, and the accuracy of determining the hypocenter of the e~rth-
quake is lowered in this case. This pertains prir.~arily to the earthquakes ~
- located in the boundary region.
The parameters of strong earth~uakes with ~i-4.5 are then more precisely
determined at the Earth Physics Institute of the USSR Academy of Sciences
using the data of the regional stations and the teleseismic world network
with good encirclement of the epicenter with stations. Therefore all of the
earthquake parameters placed in the seismological bulletin of the network
of reference seismic stations of the USSR and in the catalog for the
"strong earChquakes in the territory of the USSR" are more exact. For
this earthquake with more precise determination of the coordinates of the
hypocenter, a magnitude is defined. The magnitudes (PtL and ~up~) and the
energy class (K) are determined in accordance with the instructions on pro-
cedures for performing and processing observations at t~e seismic
stations of the united system of seismic observations of the USSR, 1966.
For rela~ively strong earthquakes numbers are placed in the cgtalog by
which they are easily found on the epicenter map. For Carpathia, the
Caucasus, Northern Tyan'-Shan', Altay, Yakutia and Sakhalin, the numbers
- are given for Che earthquakea with K?11; for Central Asia, Baykal,
and Kamchatka, with K; 12;for the Kuril Islands~with M> 5.5. In
addition, the numbars of the regions are placed in the catalog in
accordance with the diagram for separation of the zone into smaller
regions for seismotectonic areas~and macroseismic data are presented
which were obtained in small amount and are not included in the text of
the item.
For regions with relatively',~ow level of seismicity or a smnll number of
seismic stations, two recorded earthquakes are put in the catalog for
which the epicenters are determined (Carpathia, Crimea, Kopetdag,
Northern Tyan'-Shan'), for Yakutia and Sakhalin with K;8, for the Far

- STRONG EARTHQUAI:ES IN THE TERRITORY OF THE USSR
[ArCicle by I. V. Gorbunova~ ~
_ A brief survey has been made annually of the seiamicity of the territory
of the USSR on the basis o� Che data on eartP~quF~k~ parnmeters with M�4.5
taken from the Seismology Bulletin of Che network of USSR reference
seismic stations. _
- In 1974 when compiling this bulletin the level of mngnitude from which
the parameCers of the earthguake centers are usually determined was
reduced to M~4, which made it possible to make small-magnitude efirthquakes
representative in many zones (M-4,5). The missing of such earthquakes
is discussed in the seismicity survey for 1973.
The parameters of the earthquake centers are determined in the first
- version by regions according to the daCa from the regional stations. At
the Earth Physics Institute the parameters of strong earthquakes are more
precisely defined for which the results of the regional and teleseismic -
stations of the world network are used with good azimuthal encirclement
of the epicenter by the stations. In individual cases only, when there
were few data for more precise determination of the epicenter or the
determination by the regional data is confirmed by more precise determina-
tion by regional and teleseismic data, regional data are included in the
catalog (K=12.13). This refers primarily to the earthquakes with M=4.5
, from the Baykal zone and the northeastern part of the country. The epi-
> centers, ~ust as before, were determined on a computer by the EPI program. _
Numbers are entered in the catalog for strong earrhquakes with Ma5.5,
- by which t`~ey are easily found on the epicenter map (Fig 1).
There were 284 earthquakes with Mw4.5 in the USSR in 1974. This number -
_ includes the earthquakes at Gindukush and the Kurilo-Kamchatka Arch but -
with MaS. The distribution of the earthquakes with respect to magnitudes
and seismically active zones is indicated in the table. By the previously
adopted magniLude of the provisional deformation in units of 1010 ergs1~2
a comparison G?as made between the leve.l of activity of the seismic zones,and
its variation with time for the last 16 years is illustrated for four
seismically active zones (Fig 2, 3). An analysis of the epicenter map, -

the tnbles nnd Che preaented grnphs indic~Ces thnt, ~ust as before, the
mosC active region in 1974 was ~h~ FAr East~
The number o~ earChquakes with K~12 for which Che magnieude was determined
is :Lnc~.uded in parentheses.
Here tt~e greatest activity was observed in Che north and south oE Che
Kuri1 Isl~nds. In the north it was a continuation of the aftershock
activity ~fter the strong ear.thquake of 28 February 1973. In the epi-
central region of this earthquake two earthquakes were recorded in May
= with M=6.7 And 5.8 (Nos 18, 19). In the souCh, souCh of the island of -
- Shikotai~, an e~rthquake occurred on 27 September with M=7,2 (No 28),which
was almost not accompanied by aftershocks. The activity of the central.
part of the Kuril Islands increased significantly by comparison wiCh the
past year, where an earthquake with M=6~9 (No 21) was observed on 28 July
accompanied by a large number of repeated shocks. An earthquake of
almosC the same strength occurred on 9 September at 0732 hours (',Vo 29)
soutl~east of Urup Island with M=6.8. ~
In the territory of Kamchatka, the Avachinskiy Bay and Komandorskiye
Islands were distinguished somewhat wiCh respect to the level of seismic
activity. The strongest earthquake was the e~?rthquuke of 27 July with
, M=S. 9 (No 20) .
_ In the Sea of Okhotsk the epicenters of the large earthquakes are arranged -
in a belt extending from south to north through its central region. The
str.ongest earthquake occurred at a depth of 435 km on 20 December with
mp~=5.5 (No 37) in its central region.
' In Sakhalin, the seismic activity was manifested basically by weak earth-
quakes, the strongest of which was on 17 August at 1513 hours with M=5.4
occi~rring northeast of Sakhalin Island.
- In second place with respecC to the level of seismic activity is Central
, Asia. Here it is possible to isolate two regions: Northern Pamir And
- Gindukush. In Northern Pamir, in the vicinity of the articulation of the
- Sarykol'skiy and Zaalayskiy ridges, a strong earthquake with M=7.3 (No 2)
occurred on 11 August at 0113 hours accompanied by a large number of
_ repeated shocks. The earthquake was felt over a large area, and at a
distance of 40 km from th e epicenter its intensity reached force 6-7.
In the epicentral region its intensity could be force 8 with a depth of
center of 5 km. The more precisely defined epicenter agrees better than
the regional one with the macroseismic data. By the macroseismic data ~
two versions of the isoseisms were drawn by different authors. The aiter- -
shock distribution is still in favor of the first version. However, this
earthquake will be investigated in still more detail by seismologists
_ and geologists, and the f inal results of the research will be published. _

3 not noted - ~
An earthquake was felt with force 6 in the kishlaks ~Central Asian villages]
of Northern Karagach (No 1) and Southern Karagach (No 2) (Fig 4, 'rsble S).
Here the earthquake manifested itself suddenly by a strong, sharp verti-
cal shock which was accompanied by a rumble and roar. The residents of
these kishlaks awakened and ran out of Che house. The doors of the rooms
opened and shut from the oscillations. The rumble was audible in the
direction with azimuth 240-260�. The electric lights swung in the same
direction. In both villages there were only type A structures (pise).
, The wall coverings fell off in chunks in some of the commercial buildings
as a result of the tremor. In the walls of the residential buildings,
especially under the roof and floor beams and in the corners of the walls
through cracks were observed. Subsidences (1-3 m3~ of the dehydrated
loess-like loams occurred in the road cuts. In addition, in the Druzhba
kishlak (No 5) (force 5--6) exfoliation of the walls and collapse of the
plaster in chunks of 2x2 meters occurred from the tremor.

There ~re mncroseism~.c data on Che wenk earthqunke with K~10 on
28 December at 0807 hours. Tt was felt in Dagan (8 km) Eorce 5,
Chubelc (15~ and nadarak (15) force 3~4, Khtrm~ndzhn (45), �orce 2-3~
5ix mnre earthquakes oc;curred in thie zone wi.th K~12 (Nos 8, 9~ 20, 43,
47, 164) and one with K~13 (No 163) at the pointa of occurrence of ehe
deep P~mir~Gindukush earthquakes. With the exception of No 16, 10 and 47
a11 of Chem had hypocenters at an intermediate depth of 70 lan, and
obviously they must be considered together wieh the deep earChqua';es.
In Southern Tyan'-Shan' (zone TIT) only two strong earthquakes were
recorded in 1974: 4 January at 0927 hours with Km14 (No 1) and 26 November
~t 1250 hours with K=12 (No 153)~ They both occurred in the central part
of the Kokshaal-Tau Itidge~ South of them in 1973 increased seismic activ-
ity also was observed, but the largest earthquakes at that time had an
energy class of only K=12. In Che rest of Southern Tyan'-Shan' 140 weaker
earthquakes were recorded.
In Central Tyan'-Shan' (.r,one II) in 1974 more than 100 earthquakea were
noeed. The strongesC of them with K=13 (No 11) occurred on 20 February
at 1143 hours in the eastern part of the Fergana Vnlley near Oah at a
depth of 15 km (Fig 5, Table 6)~ It was felt at a distance of up to
337 km. The strongest tremors at force 6-7 were observed in a radiua of -
13 km. Five zones were isolated on the isoseism mapc force 6~7, 6, 5,
4 and 3.
In the force 6-7 zone the earthquake was accompanied by a dull rumble
resembling the sound of a rock slide in the mountains. The large poplars
- along the road rocked sharply from the shock, as a result of which snow
fell off them. The electric power line poles shook. The chimney on the
roof of the food store collapsed and fell on the sidewalk. In individual
buildings made of.baked brick cracks formed in the walls, and several
pieces of plaster collapsed.
' In Kurshab~in the three-story building of the preparatory school thin
cracks appeared in the wall::. Sloping, intersecting throu~h cracks were
formed between the windows of the stairwell. A crack was noted in the
earthquake control strip between the first and second stories. Structures
~
made of raw brick were damaged severely. Many of the houses rattled,
and in some of them through cracks appeared and large chunks of plaster
fell out. The hospital building was seriously damaged. The patients were
evacuated. A partition fell down in the tea house~ For example, 20% of
the chimneys werp comple~ely or partially destroyed.
In the force 6 zone the earthquake began with horizontal oscillations
with a loud rumble. Then a sharp vertical shnck occurred (Kara-Su). The
two-story school building rattled. The bulletin boards fell off the
walls in the hall. The seams split at the points where parts of the
building were ~oined together.

Fine cracks were formed in the walls and also at the points where the
stoves 3oined the walls in individual buildings made of raw brick.
In the force 5 zone the earthquake was noticed by everyone inside build-
ings and many in the open areas. The underground rumb]e of moderate
st.rength was heard basically inside buildings. The earthqu3ke caused
some of the people to panic. Cases of tipping of unstably standing
ob~ects and the appearance of fine cracks in the houses made of raw brick
were observed. _
Another earthquake in the Fergana yalley with K=12 (No 5~ was noted on
22 January at 0608 hours near the city of Fergana (Fig 6, Table 7). It
occurred in the vicinity of the Frunzenskoye village where it was observed
with a force of 6. Its center was located at a depth of 25 km. Four

In tl~e force 6-7 zone in the rayon center the Frunze earthquake appeared ~
in the form of three underground shocks of a vertical nature accompanied
by a dull rumble. '~he buildings made of raw brick were damaged most
severely. Thus, in Che club which was built in 1957, through, basically ;
inclined cracks occurred in the wall and also at the corners of the walls.
In many individual buildings through cracks appeared in the walls. The
pipes were destroyed in some of Che houses. In many of the buildinga made -
of baked brick fine cracks appeared primarily on the southern and eastern
walls (the dining room building). Fine cracks appeared in the wall plaster
and also between the ceiling blocks in reinforced concrete buildings.
In the three-stor,y Frunze Rayispolkom building which was put into operation
in 1972, fine cracks were formed between the ceiling blocks, in the
walls of the rooms and halls horizontal fine cracks 20 to 30 m below
the ceiling. In a one-story store building a crack occurred throughout
the entire west wall. As a result of deformation of the metal and glass
part of the building, the glass was broken.
In the force 6 zone the window glass was broken in the hospital and school '
buildings. Trees swayed, the wooden awning of the tea house shook, and
packages of tea and pastries fell off the shelves of the produce market.
Several empty boxes stacked on top o~ each other fell down in the warehouse.

- The isoseisms of the earthquake of 13 April 1974 have an elliptic shape
elongated in the northwescerly direction. The force damping coefEicient
was 3.7.
The earthquake was noted with greatest force 5 in the villages of Fogelevka,
Abay, Uchk~iduk, Yenbekshi and Karatas, on the iarm of the Kuyuk sovkhoz.
The area occupied by the force 5 zone amounts to abouC 1$00 km2. In the
given region Che earthquake was felt in the fArm of short shocks
' accompanied by an underground rumble similar to the rumble created by a
passing motor transport. _
- A weaker earthquake with K=11 was recorded on 24 February at 06'll hours
_ in the southeastern spurs of the Nuratau Ridge~ Since it occurred in
a thickly populated area near the rayon center of Gallyaaral, there are
quite cemplete macroseismic data on it collected by V. K, Iodko (Fig 9,
Table 10). It was felt at a distance up to 133 km. Four zones were
_ isolated on the isoseism map: force 6, 5, 4 and 3.

charucter3zed by the lowesC level o� seismic activiCy by comparison with
ehe rem~ining parts of Ceneral Asia, Only two earthquakes wiCh Ks12 and
abnuC 40 mild shncks took place here.
The first powerful earthqunke with K=12 was recorded on 4 Marcli at 1430
hours (No 14) 40 km north of Chilik, within the boundaries of the south-
western end di the Altynemel' Ridge (~'ig 10, Table 11). As a result of
inaccessibility at Chat time of year the locaCion of the epicenCer was
not investigated. In the populated places located closest to the epicenCer
the earthquake was felt with force 4-5; therefore the maximum intensity
of the epicenter was supposedly esCimated aC 5.
- The earthquake was Eelt ir. the form of several shox't shocks accom~~anied
hy a strong underground roar resembling the movement of a heavy mc?tor
transport. Its isoseisms were elon~ated in the northeasterly dir~ction
parallel to the strike of the basic geological structures of the l)zhungarskiy
Alatau.
The earthquake on 2 July at 1641 hours (No 39) was recorded in thc~ south-
eastern spurs of the Kirgiz Ridge. It was felt in the populated rireas of
Minkush, Chayek and Chu located at a disCance of 85-170 km from ttie epi-
- , center with a force equal to force 4, and in Fergana (90 km) with a
force of 3-4.
Two earthquakes with K=16 and 40 earthquakes with K=12~-15 occurred in
Gindukush (zone V). The strongest earthquakes, ,just as before, were
located in the central part of Gindukush~ The first of them with m=7.3
occurred on 30 July at 0512 hours at a depth of 200 km (No 49) (Fj.g 11,
Table 12). It was felt over a large area. The force 6 oscillati.~ns were
nated at a distance �rom 130 to 200 km, and force 3 to 700 km. Force 6,
S, 4 and 3 zones were isolated on the isoseism map.

In the populaCed places of the forcp 6 zone, strong, prolonged hori_~~ntal
oscillaCions were felt which were accompanied by a rumble. Cracks were
formed in the walls of the buildings, the plaster fell off in some of the
old buildings, and some of the old fences fell down. Rock slides, collapse
of the loess slopes and damage to communications and electric power lines
were observed in the mounCains.
In the force 5 zone the osciZlations caused panic among the residents.
Many ran out of the houses. Unstably standing oh~ects fell, and hanging
ob~ects swayed. Water splashed out of the basins~ An underground rumble
was heard~

~'~nother, weaker earthquake with m=5.7 was recorded o~:t 10 December at
0141 hours at a depth of 205 km (No 158). There is less macroseismic
information about it than about the preceding one. The greatest tremors
of force 4 were noted in Kulyab at a distance of 170 km. In Vakhsh (188 km)
they reached force 3-4, and in Pyandzh (135), the Golovnaya Hydroelectric
Power Plant (200), Shaartuz (.205~, Nurek (235~, Mirak (.270), Dzhirgatal
(325), Leninabad (435~, Samarkand (460~ and Tashkent (555) it was force 3.
In the central part of Gindukush, an earthquake with K~15 at a shallower
depth equal to 180 km o~curred somewhat earlier on 13 May at 1740 hours
(No 24). It alao was felt over a significant area in a radius of 545 km.
The macroseismic effect in the closest populated place Khorog (125 km)
was estimated at force 4-5, in Ushar (345), force 4, in Iol (153),
Kulyab (180), Khirmandzha (218), force 3-4. In Pyandzh (215 lan),

corresponded tn values of 2.0, 1.0, 0.7, 0.5, 0.2, 0.1, 0.05, 0.02, O.bl.
When constructing the activity map with circular averaging areas, the
seismotectonic situation of the area is not taken into accaunt. In ordcr
to determine the value oE the activity at any point of the investigated
r.one it is necessary to select five epicentera in the area of the circle
oE averaging. In the general case these earthquakes can belong to
different seismogenic regions, thus confusing the actual pictiire.

It appenrg more logicul to use the patterns of elliptic shape when per- -
forming the construction encompassing the eArthqua~es within the limits
of nn~ deEined structure, for the basic geologicnl structures of the nren
have linearly elongat~d shapes. Therefore the circular patterns with
defined rndii of averaging were transformed to elliptic retnining the
corresponding areas of averagin~. Seginning with the longitudinal and
transverse dimensions of the genlogical structures of the area, ellipses
were selected with a ratio of the axQS of 1t1.6. When calculating the
_ activity map, the major axis of the ellipse was oriented parallel to
che ~trike of the geological structurp~.

LAItTFIQUAK~5 OF' AL'TAY ANU SAYAN ~
[Areirle Uy I. U, Tsibul'chik, A. G. FilinaJ
The seismic observgtiot~s in Altay-S~yan Oblast in 1974 were realized by the I
s~me network of ataeions as in 1973. The equipment and the procedure for '
processing earthquakes also were unchanged. ~
_ WiCh respecC to the toeal number of earthqun~Ces (~ig 1, 2) 1974 w~a
approximately on the 1973 level. The number of earthquakes with K312
increased somewhat:
K 9 10 11 12 13 14 ~
No of earthquakes 68 14 12 3 - 1
As before increased seismicity characterized the vicinity of the Ure~-
Nurskoye earthquake of 1970. For S years after the basic shock th~: series
ef aftershocks continued, rhe distribution of which with respect t~~ energy
cl~sses was as follows in 1974:
K 5-7 8 9 10 11 12 13
- No of aftershocks 51 34 8 2 - - 1
The total number of aftershocks in 1974 was somewhat lower than in 197~.
The distribution anomaly of the aftershocks with respect to energy classes
in 1973 is not observed in 1974.
In Fig 3 it is quite obvious that in spite of the general trend toward a
reduction in seismic activity (with respect to aftershocks) it remains on
a higher level than for the 7 years preceding the Ureg~Nurskoye earthquake.
In .1973 the possibility of the occurrence o� relatively strong earthquAkes ~
at the ~unction of the Westerr. Sayan and Shapshal'skiy Ridges was noted.
The observaCions of 1974 con~irmed this propositions on 5 September a
12Ch energy class earthquak~ occurred there.

Figure 3. Graph of the behavior of Figure 4. Beh~vior of the seismic

enrthquake (~=50.5 to 52~0�; a=80.5 to 90.5�) -
Key: Key:
1. years 1, earthquake with K=12
F'ig 4 shows the behavior with Cime of the seismic prncess in the viciniCy
of the earthquake of 5 September for the period from April 1973. After a -
brief series of aftershocks o� the earthquake of 30 April 1973, the course
oE the seismicity equalized before September 1974 when a sharp blip is
observed preceding the second earthquake of energy class 12 in this region
occurring on 5 September. It is interesting to noCe that the earthquake
_ of 30 April was accompanied by an insignificanC ntm~ber of aftershocks,
whereas after the earthquake of 5 September came numerous repeated shocks.
Their distribution with respect to energy classes is as follows:
K 5-7 8 9 10 11
No of aftershocks 50 22 5 1 1
As was noted in Che preceding collection, the aftershocks of the earthquake
of 30 April 1973 occupied an anomalously large region, although many of them
were located directly near the main shock (Fig 5, a). During the period
from August 1973 to February 1974, the epicenters were arranged uniformly
with respect to the entire investigated region (Fig S, b), whereas the basic
seismic energy is released in the same small section. The period from March
to August 1974 (~ig 5, c) is also characterized by uniEorm distribuCion of
the epicenters with respect to the entire reginn with predominance of strong
earthquakes along its periphery. The sharp blip noted on the graph for the
behavior of the seismic process heginning on 2 September includes the fore-
shocks of the earthquake of 5 September basically located in the vicinity
of the future earthquake. The region uf greatest concentration of the
aftershocks of the earthquake of 30 April 1973 is in that period aseismic
(Fig 5, d). -

th~ obscrvations of the seismic st~~ttons of Char,~, Central Kalar, and 'Cupik

'Che t~rocessing of the earthquakes of the Amur region recor.ded by three or
- more stativns was carried out by t}~e merhod of intersections with resPect
to t', and tg. The epicenters of the earthquakes recorded by any c~ne st.7tion -
were found by the atimuth to the epicenter and the epicentral dis~ancc
calcul~ted on the basis of the hodograph tS-tp=f(A). Tn both cases tlie
.1eEEries-Bullen hodograph was used. The errors in determ~ning the -
roordinates of the epicenters did not exceed 25~50 km.
'i'he ener~y of the earthquakes was calculated as 1;=1g C joules; the Rzutian
scale WSS used in the Yakut branch of the Siberian Departmen[ of the USSit

'I'he mc~st seismically hctive is the Stanovoy Ridge ad~acent on the norCh Cn
the investigated region. T'he sp~tiA1 arrangement oF the centers of Che
earel~qunkes was caused by the Stanovoy deep suture, along the system of
Eracturey of which the basic mass of shocks is tr~ced. The Stanovoy suture
r:ttends subl~Cir..udin~lly from the Olekma River Cn the bzhugdzhur Ridge.
'I'he grentest in Priamur'ye was nbserved in the vicinity of the Tukuringra
ltidge where on 13 June 1972 and 2 November 1913 two of tlie Eorce 7 tremors
were noCed with rt=5.5-5.6. In 1974 the Tukuringra Ridgc in practice was

The numerous seismic staCions of the ArcCic zone and the provtsion of them
wit}i rq~iipment in 1974 did no~ change by comparison with Che pa:.�C yenr [1.].
As before only the epicenters of earthquakes with M>4 ~~re del:err,~ined
reli~7h.ly. 'The weaker earthquakes are usually recorded by one neArby
sCation, and their parameters are determined insufficient~y exacCly. Tt~e
ma,jorlty of the recorded weak earthquakes ~re interpreted only with respect
ro ti~e epicentral distance and the energy class (K) or t}iey are noC
internreted in general. For example, the analysis of the observatLon -

CO[1tt~C~~d wirh the egat~rn Sakh~lin propoged deep fracture. On rhe eastern
bnundary of this region on 17 Augu~~ at 0513 hour~ Greenwich time, Che etrong-
e~t ~arthquake in Sakhalin occurred with a magnitude of M e 5.2; iCs depth
according to the inetrument data ie estimated at 10-20 km. An hour before
this pnrehquake an underground ahock was recorded with M= 4~2 at the eame
depth gg c~n b~ con~ider~d among the preceding Qarthquakes~ The earChquake
of 1~ Augu~r wag not accompanied by repeated ahocka within the limits of the
in~trument r~cording pogsibilities~ In 19~0 tc~ 1973 there were also r,~o
~nd~rground ghocks r~corded in the vicinity of the epicenter of the earth-
quak~ of 17 Augn~t 1974. Two underground shocka (Novemb~r-December) with
t~ s 7 to 9 w~re noted enst of Shmidt Penineula or 74 km south of Che earth-
quak~ of 17 Auguat; in SeptembQr, :^rtht!aet of it, at approximately the same
diseance (outside the boundariee of the region)~ an earthquak~ wae noted with
K= 9-10. In other parts of region No. 2 the aeismicity was mnnifesCed only
souCh and southwest of the city of Okhi where the Ekhabinakoye earthquake of
1970 (M = 4.2) and the underground shock of 19 May 1972 With M~ 4.5 occurred.
All of the earthquakes which occurred in 1974 in the Northern Sakhalin region
(No. 1) can be broken down into three greups: northern, central and south-
western. The underground shocks in the northern part are baeically associated
witf~ the center regions of the Northern Sakhalin earthquakes in December 1967
(SJ and January 1971. The strongeat of them was in April with K~ 9. In
the central p~rt of region No. 1 of the epicenters of the earthquakes were
located between 5hmidt Peninsula and the epicentral region of the earthquake
with M~ 5 occurring in November 1973; obviously all of Chem can be considered
afterahocks of Che latter. By comparison with 1970-1973, in 1974 increaged
g~ismicicy was observed in the southwestern part of region No. 1 where the
Nyydovskoye earthquakes occurred in 1962 and somewhat more to the aouth.
Four underground shocks were noted here with K= 8-9 and six with K a 6-8.
The seismicity of region No. 3(the Eastern Sakhalin Ridge) was on the 1973
level. Only one earthquake was recorded here with K= 8-9 east of T�~+movskoye,
and northeast of it, a group of earthquakes with K< 8.
- In 1974, just as in 1971-1973, no earthquakes were recorded under the bottom
of Aniv end Terpeniy (region No. 5).
In the eastern part of Southern Sakhalin (region Na. 6) underground shocks
occurred only with K< 8, the epicentera of which are located along the con-
tact of the Susunayskaya Valley With the Susunayskiy Ridge and the Korsakov-
skiye Plateau. In 1973 two earthquakes were recorded here with K> 8. In
the last five years, the seismicity of this region was the least in 1974.

A significanC evenC in the s~igmic life of Che reginn wns Che ghnck of -
24 January aC 1912 houra (M = 6.1, H= 30 km). The two shockg following
it in the next 24 hours had M d 5 and 5~4 and were located at somewhat
greater depthe (50 and 40 km r~Rpectively). ~'he data on thei mechanism nf -
Che cenCers o� these earChquakes turned out to be very aimi'lar, ~ust ~s
the nature of the sCressed staCe in their vicinities: their centers were
under ehe effecC of ehe near horizontnl compressive stresses and the ten-
sile seress more steeply orienCed toward the horizoneal. One of the pos-
sib'le frac ture planes wns oriented submeridionally, and another, aub-
latiCudinally wiCh dips to the east and eo the west reapectively.
Ttie second strong earthquuke following on 8 November at 2123 hours wiel~
the epicenter on the souCti shore of the island of Hokkaido was Che strong-
E:st in ehe region and had the greatest macroseismic effect for 1974. Ac-
cording to Ctie daCa of the Japanese Meteorological Agency, in ~~okkaido
the earChquake appeared wiCh force 5 accordittg to the Japan~se scale whicti
corresponds to force 8 by the MSK-64 scale.
The movements in Che center of this e~rthquake (Table 4) had the strike-
step naCure. Along one of the possible fracrure pl~nes with northwest ro
southeast strike and dip under the Island Honshu, overthrust of tt~e con-
tinental s ide of the fault on the ocean side was observed. With respect
= to the second of the possible fracture planes with northeast-southwest
strike and dip under the ocean, an uplifC of the ocean side of the fauLt
with respect to the continental side with a shift to.the south was noted.
The grnph of ~he recurrence rate of the shallow-focus earthquakes of Che
region calculate4 on the basis of the information on the number of earth-
quakes with M= 4 to 5.5 has the parameCQrs a= 4.61 and b=-0.82 and it
characterizes the low activity at a depth of H= 0 to 80 km.
In the 5ea of Japan seven earthquakes were recorded wiCh a magnitude not
exceeding M= S aC depths of H= 160 to 280 km. The mecl~anism of the center
ot the earthqualce on 1 February at 0323 hours with H= 160 km and mf,v = 5.0,
the epicenter of which was locaCed near the northwestern shore of Hokkaido
(see Table 4) was determined.
In the Sea of Okhotsk in 1974 it was necessary to determine the coordinates
of the hypocenters of 23 earChquakes with 4< M< 5.8. One of these enrth-
quakes which occurred on 21 April at 0208 hours with irs epicenter in the -
western parC of the Southern Okhotsk deep basin was shallow-focus: its
depth was 25-30 km, magnitude was 4.9. According to the daCa on the mech-
anism of the center of this earthquake, one of the possible fracture planes
in the center has a strike from northeast to southwest with dip to the north-
west, and the second, from southeast to northwest~ and it dips to tt~e r,~orth-
east. The center of the earthquake was under rhe effect of the horizontally
oriented tensile stress and is characterized by strike-slip movement.

'Pwo oeher earehquakes wiCh hypocenters noreh o� the I~lnnd of liokknido at
depehe of H~ 192 Co 225 km had analogous eCrike of Che Eractur~ planes,
but Cheir ceneers were under Che condiCinna of the hnriznneally oriented
compressive stress, and ~hey were characCerized by serike-sLip movements,
The center of the earChquake of 20 December nt 1638 tiourg wieh hypocenCer
in rhe midsection of the Sea of Okhotsk w~a under the eFfect of Che more
horizontally oriented Cenaile stresses and eteep compresgive stresses~
The nnture of the movemenr in the cenCer was atrike-e1ip. -
The centers of the earthquakes in the 5ea of OkhoCsk formin~ the norCh-
enstern group of epicenters were predominantly under the effect of the
close to horizontal Censile stresses and steeper compressive sCr~saes.
The movements in their'cenCera can be considered as strike-slip. 7.'wo
ottier shocks in Chis group were characterized by movemenCs at Che center
of opposiCe sign.
The above-presented description of the manifestations of the seismic ac-
tivity of the Kuril-Okhotak region malces it possible to note the following
basic features of it.
1. The greatesC seismic activiCy was noted on Che flanks of the Kuril
Archipelago. However, whereas in the Paramushirskiy Rayon the nature of
the seiamic activity did not change by comparison with 1973 and was a con- -
tinuation of the process of the aftershocks of the earthquake of 28 Febru-
ary 1973, in the Kunashir-Shikotan region a significant change was obaerved
in the nature of Che seismic activity. The accumulated seismic energy in
tiiis area was discharged in the form of a single act--the earthquake of
27 September wfth M= 7.2 which not accompanied by afterahocks.
2. In 1974 the Cotal seismic energy of the earthquakes with intermediate
- depth of center was frequently more. In the Onekotan-Matua region it was
twice the energy of the shallow-focus earthquakes. In the vicinity of
Hokkaido, the energy of Che earthquakes wiCh intermediate depths of center _
was an order higher than the energy of the shocks with H a 0 to 80 km.
3. The field of the tectonic stresses affecting the centers of ~he Kuril
shallow-focus earthquakes was like, for deeper seismically active layers
of the Kuril-Okhotsk region, the nature of the tecConic stress field was -
more uniform. -

STRONG EARTHQUAKES OF THE WORLD
[Article by A. I. Zakharova, A. M. Kondratenko, L. S. Chepkunae]
In 1974, the tradiCional survey of the earthquakes of the world was performed
with respect to the earthquakes with MLH, mPV > 6.0, and it was supplemented
by Che eatimates of the dynamic parameters of the centers of the earthquakes
- with r~H ? 7.0: the seismic event M~, length of fracture L, magnitude of
the movement u, decrease in stress The seismic moment is the force
characteristic of the center which can be defined as the amount of energy
required for relative displacement of the edges of the fracture a diatance
u fo~ a fricCional st.ress equal to the magnitude of the modulus of shearing
el~isticity u. The decrease in stress ~cT is the difference between the mag-
ni~ude of the stress in the center region before the earthquake and after
it.
1. General Survey
The survey of strong earthquakes of the world in 1974 was made in accordance
with the materials of the United System for Seismic Observationa of the USSR
and the National Seismologic Center of the United States (NEIS) [1].
The geographic distribution of strong e~rthquakes of the world in 1974 is
illustrated in Figure 1.
The distribution of the number of strong earthquakes of the world with M> 5.8
as a function of their magnitude is presented in Table 1 where the results
of 1974 are compared with the corresponding average values for the ten pre-
ceding years.
From the table it is obvious that in 1974 the recurrence rate of the earth-
quakes of different magnitude differ somewhat from their average recurrence _
rate for the preceding years primarily as a result of the earthquakes with
5.8 < M < 6.8.
The magnitude instruments of the strong earthquakes made it possible to esti-
mate the seismic energy released from their centers by the recalculation
formulas [2]:
E= 101 1� 8'}' 1�~M 5. 8 ? Y. 5IT1
= 10 ergs. (1)

5,8 103�) corrections were introduced for the diver- `
gence correaponding to 0= 100�, aincefor 103� similar corrections are not
, available. The consideration of the directionalnesa of the radiation from
the center Was made only by introducing the average value of R~ ~ 0.4 ~9J, ~
qince for the given earthquakes ae had no informatinn available about the -
mechaniam of the centers.
The calculated values of the dynamic parameters M~, r, AQ, u are preeented
in 'fable 3. Here an estimate is presented of the energy E calculated by
the magnitu~.e M in the eurface waves (1), and ES, by the dislocation in the
ceciter und the stress released during formation of the fracture [10~:
ES = Z eou"A . (4)
A comparison of the energies E and E indicates that for all of the earth-
quakes E is less than E on the average by one or two orders. Obviously
this dif~erence is connected with the fact that in formula (4) a aip,nificant
part of the energy released as a result of the r.upture and slidiag along the
fracture during the earthquake is not taken into account.
In conclusion, let us note that the values obtained for the dynamic parameters ~
muse be considered only as estimates, for they are determined by the data from
one station considering the mean value of the directionalnesa function of the
radiation from the center.

This article is devoCed to a description of the seismicity of the Carpathians.
The most acCive regions in the Carpathian zone in 1974 were two regions:
The northwestern region and Vrancha. Procedures are described which were -
used when determining the parameters of the centers of the earthquakes, and
a table is presented of the basic parameCers of the equipment installed at
the Carpathian Seismological Stations of Che Ukrainian SSR, the data on which
were used when determining the coordinates of the hypocenters. For Che
force-5 Transcarpathian earthquake in the vicinity of Irwava there are de-
tailed roacroseismic data. An earthquake catalog is preaenCed.

Earthquakes of A1tay and Sayan. Tsibul'chik, I. D., Filina, A: G.,
ZEMLETRYASENIYA V 555R V 1974 GODU, Moscow, Nauka, 1977, pp 106-113
A study is made of the seismicity of Altay and Sayan for 1974. It ia noted
that Che seismic activity is approximaCely aC the 1973 level. The moat
aceive are th~ regions of the Shapshal'skiy massif, Northeastern Tuva and
Mongolian Altay. In the vicinity of the Ureg-Nurskoye earthquake on 15 May
1970, the continuation of a series of aftershocks is observed. A sCudy ia
_ made of the behavior of the seismic activity in the given area for the
- period from 1963 to 1974. It is ~oted that the aeismic activity in 1974
- still exceeds the background observed for 7 years before the main shock.
For rhe regions of the ea'rthquakes of 5 September (K = 12) and 29 November
(K = 14) a study is made of the behavior of the seismic process in time and
in space. For the earthquake of 5 September the mechanism of Che center
' was determined and an analysis was made of it. The article is accompanied
by an earthquake catalog.
