Near Field Small Earthquake Long Period Array
Abstract
This report describes some of the accomplishments achieved during the second year of a cooperative program concerning the detailed nature of seismic radiation from earthquakes. Efforts have been divided into three areas, to obtain broad-band observations in the Bear Valley region, to develop the theoretical framework needed to treat seismic data in general, and thirdly, to use this formalism to model earthquakes. This year's semi-annual report contains a theoretical treatment of modeling local earthquakes as shear dislocations in a layered halfspace. Numerous synthetic seismograms were presented along with some preliminary fits to observations involving strike-slip events. This report presents a generalization of the technique to arbitrary oriented dislocations.
