CATALOG OF LOCATIONS OF NUCLEAR-EXPLOSIONS AT BALAPAN, KAZAKHSTAN, 1965 TO 1985

Geographic locations for 81 explosions at the Balapan test site in Kaz akhstan are derived with a precision of about 200 m from time-sequence LANDSAT MSS and SPOT satellite images combined with teleseismic epice nter estimates. The LANDSAT images were registered to ground control p oints from a SPOT image to provide high relative accuracy for feature comparison. Initial seismic location estimates for the explosions were derived using joint epicenter determination. For most events, there i s little or no ambiguity in the association between seismic events and image features, owing to the frequency of the LANDSAT images and the spatial separation between explosions.
