Technical Report ·
OSTI ID:6996178
This study describes four related research efforts. Section A reviews P-wave spectral models for earthquakes and explosions to assess their implications for high frequency seismic discrimination and test these on North American and central Asia data sets. Section B describes some simple forward modelling to quantify both the moment and mechanism of the tectonic release of the Soviet JVE. Using 10-20 sec surface wave data the tectonic release moment is found to be 10-20% of the explosion moments and have a strike-slip mechanism. Section C describes a new spectral model for seismic radiation of a circular crack failing in tension. Section D describes a study of the tectonics of the South Caspian region. Earthquake mechanisms show over-thrusting of the South Caspian basin from the north, west, and south. The combined effect will lead to the eventual destruction of the South Caspian Basin and the possible formulation of intermediate depth seismic zone within the continental interior similar to the Hindu Kush.
