A Computer Method for Determination of Valid Focal Mechanisms Using P Wave First Motions

Seismological Research Letters, 1977
Most techniques for determining focal mechanisms attempt to find a unique focal mechanism. However, for the usual case in which only a limited number of P–wave first motions are available, the focal mechanism can only be limited to a domain in which any solution will be equally valid.

Automatic Determination of Full Moment Tensor Solutions from P-wave First Motion Amplitudes

Proceedings, 2009
Standard microseismic monitoring nowadays focuses on event locations, but information on detailed source parameters is rarely extracted. The estimation of full moment tensor solutions of microearthquakes may provide valuable information on presence and geometry of faults as well as stress fields and changes thereof. Therefore, we included a full moment

Possible Method for increasing the Signal–Noise Ratio in the Detection of the First Motion of a Refracted P-Wave

Nature, 1961
IN seismology a method has been developed of examining the focal mechanisms of earthquakes by studying the azimuthal variation of the first movements on seismograms1. In extending this method to differentiating between small earthquakes and explosions a basic experimental problem is the detection of the initial movement when its amplitude is of the ...
