MODEL STUDIES OF SEISMIC ENERGY DISTRIBUTION AROUND DIFFERENT TYPES OF SOURCE. Final Report

Abstract : Several seismic patterns from earth model studies in the presence of velocity discontinuities near the source are examined. Five typical conditions have been studied: a boundary passing thru the focus; one to one side of the focus; two boundaries symmetrically on either side of the focus; a similar arrangement with the two boundaries asymmetrical; and a circular area of higher velocity to s which could be studied profitably, but it does serve to illustrate the type of result to be expected.
