Seismic Source Identification: A Review of Past and Present Research Effortsriving short period (SP) P signals recorded at distances out to about 2000 kms (regional distances). In 1961–1962 it was demonstrated that unless stations can be established within 500 kms of a seismic source the best distance for detecting SP P waves is the range 3000 to 10,000 kms. At these telese

Dynamics of Seismic Sourcesurce rupture history and the far-field radiation on the basis of a few simple fracture models. A plane, two-dimensional crack model is used to show the main features of crack models and of the body waves radiated at the initial and final moments of rupture. Two-dimensional models are not very satisf

Inelastic Processes in Seismic Wave Generation by Underground Explosionslosions. The later stages are similar with respect to seismic wave generation. Three sources of seismic waves from explosions are coincident in space and time, or nearly so: the explosion itself, explosion-induced tectonic strain release, and (probably) spall-closure following explosion-produced spa

Determination of Source Mechanism and Hypocentral Coordinates from Waveform Dataroutine estimation of the principal seismic source parameters (hypocentral coordinates, seismic moment tensor) for earthquakes of moderate size. Considering the usual level of global seismic activity, the analysis could eventually be applied to as many as several hundred events per year, rapidly tra

The Effect of Green’s Functions on the Determination of Source Mechanisms by the Linear Inversion ofexplosions studied are Handley and Pipkin, both detonated on Pahute Mesa at the Nevada Test Site. A variety of Gree’s functions are used in the inversions for the moment tensor to test the sensitivity of the procedure to assumed propagation path effects. The simplest model consisted of a half-space
