Abstract

This paper deals with a model of a source time function to compute a acceleration pulse from a small earthquake. First, a source time function for kinematic model is proposed from chain-reaction model. Fundamental characteristics of the source time function are examined by parametric analyses. Effects of source distance and surface geology on the synthesized pulses are studied. A simple relation between a source parameter and a surface pulse is proposed through model analyses. Finally, comparisons between recorded acceleration pulses and synthesized ones are presented for two small earthquakes in Japan and in California using proposed model.
