Tectonic Strain Release by Underground Nuclear Explosions.
Abstract
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 due to frictional instability. The dynamics of a circular fault model is considered as a circular rupture front that expands subsonically from a nucleation point until it suddenly stops at its final radius. It was found that both the final slip on the fault and the rise time are zero on the edge of the fault and reach their maxima at the center of the fault. This slip-time history is quite different from that of the usual Haskell model where slip and rise time are assumed constant over the fault. The far field radiation due to this fault model was studied. A new method to compute the static near field of a shallow earthquake was developed.
