内容記述 | The accuracy of the determination of epicenter and origin time of shocks is studied using the simulation method. The medium is assumed to be uniform and earthquakes occur at a certain depth. Assumed observation errors are normally distributed with the standard deviation=0.1sec and mean value=0. These errors are allotted to 30 Japanese stations nearest to the epicenter, and the expected error of epicenter location (δR) and that of origin time (δT) are calculated. The equal error contours based on the random trials (at least 128, average 200) are strongly governed by the strand lines of Japanese islands, but the minute features are different in two figures. The δT-map shows a rather narrow valley closely connected with the shore lines, while δR-map shows a flat basin of δR. | |||||
