The report describes an attempt to observe SH waves from several large underground nuclear explosions at first-zone distances (

Theoretical and observational research has been carried out in order to study tectonic strain. Theoretical calculations for a composite source model consisting

Seismic surface-wave generation by underground nuclear explosions releasing tectonic strain is studied through a series of synthetic radiation-pattern calculati

Static and dynamic methods are developed to study the elastic field produced by earthquake faulting. An earthquake is considered as the slip on a planar fault d
