SEARCH FOR NUCLEAR TESTING IN AREAS OF SEISMIC EVENTS
SINO-SOVIET BLOC
(June, August, September 1961)
This report presents the results of a search of available photography
covering the areas of 18 unidentified seismic events in the periods 8-28
June, 30 August, and 11-13 September 1961 submitted with OSI Requirement
R-175/61. The search was for any signs of preparations for, or effects of,
any clandestine nuclear testing in the Sino-Soviet Bloc. No indications of
nuclear testing were identified.
Where photography was available, an area having a radius of approxi-
mately 25 nautical miles from the coordinates of the epicenter of each
event was searched. In several cases only part of the area was covered, and
in some cases the area was partially or completely covered by clouds
and/or haze. Photography dated more than 2 years prior to the dates of the
events was not included in the search.
It should be kept in mind that characteristics of some of the photography
(small scale, poor image, obliquity, partial coverage, weather conditions,
etc.) considerably hindered the photographic search.
The following is the status of photographic coverage of the epicenters:
1. Epicenters with partial or complete photographic
coverage
16
2. Epicenters without photographic coverage
2
18
Table 1 is the list of seismic events in the order of occurence, giving
the location, photographic coverage available, and results of the photo-
graphic interpretation search.
