...C. H. Thurber; H. R. Quin; R. Saleh Abstract Geographic locations for 81 explosions at the Balapan test site in Kazakhstan are derived with a precision of about 200 m from time-sequence LANDSAT MSS and SPOT satellite images combined with teleseismic epicenter estimates. The LANDSAT images were...

... at about 3 to 4 Hz, particularly needs understanding. To gain insight, source and attenuation models are used to predict spectra of regional seismic phases ( Pn, Sn , and Lg ) for nuclear explosions and selected earthquakes near the Lop Nor, Semipalatinsk (Balapan and Degelen Mountain), and Novaya Zemlya...

... data did not allow comparison of signals from decoupled and tamped explosions or direct estimation of the decoupling effect. The well-documented Balapan DOB experiment, conducted at the Semipalatinsk test site ( STS ), Kazakhstan, in 1997, included three 25 ton explosions at depths of 50, 300...

... site in Balapan are analyzed. The data suggest that yield scaling of the source spectrum, combined with frequency selection properties of propagation on each path are responsible for the observed variations in scaling slope. Loss of high-frequency energy by attenuation causes high scaling slopes along...

... that damage is a more important source of Rayleigh waves for Balapan explosions, most likely due to better energy coupling of upgoing shock waves and stronger free‐surface interactions than for NTS explosions. Figure 1. Two scenarios for the statics of the explosion source after motions in the source...
