BL~JA=: Search of Areas of unidentified Seismic Signals
in the USQR for signs of liassive Explosions
MCMI Requisasent No. C-814-81,351
ci Project No. C T56-614
1. In response to the above requizmmnt%, a search within a
25 nautical ails (na) radius of five epicenters obtained from seismic
signals has been made for evidence of sassive explosions or land-
slides resulting from earthquakes. The first XZMLa photo coveragp
after the events was examined for the given sites. The results of
the search are negative. Ccuments on the five areas searched and
listings of photography used in the study follow:
A. Site Location: sO.( 72.62,
No evIdengi-of explosives being center near
crest of mountain range. What appears as a vent within a crater of a
volt-"4c-origin peak is located 8 na IWW of the epicenter, but there
is no evidence of recent eruption. A large crater-lilac depression was
located 25 ni k of the epicenter; this also has the appearance of a
landslide feature of geologic age.
D. Site Location: 1i2.3s 72.2=,
No unusual activity or signs of explosive use was noted.
The epicenter coordinates are located on a slope leading from mountains
to a tributary valley.

These three sites (near Uit'-Xo s were grouped to-
8ether dvs to their close proxidty. No .is of siacsive or conven-
tiooaa explosions with associated support and al (toring facilities
vets evident. The sites are locatAd in rugged mountainous terrain
whom earth sovmments are likely. Various esamles of past naJor
movement such as landslides, fallen rock, and offsetting of ridges
were observed; however, none of these features appear to be of recent
origin sinos there was no change noted in their relative positions
