Abstract:
A method has been developed for retrieving the seismic source mechanism by using a sparse network of seismographic stations. The method is based on matched filtering followed by deconvolution for the seismic moment tensor. The method requires well-calibrated instruments. The seismic moment tensor is decomposed into its deviatoric earthquake-like and isotropic explosion-like parts which together form a basis for discrimination. Very preliminary applications of the method are successful and encouraging, but the full potential of the method has not been established.
