A method of obtaining P and S travel-time curves within a "Stripped Earth"^*

XAVIER UNIVERSITY, CINCINNATI, OHIO

Abstract

A simple method is outlined for obtaining from a time-distance curve of a deep-focus earthquake a table of travel times within an earth "stripped" to the depth h, the depth of focus. The method depends on the fact that such a curve for a deep-focus earthquake has a point of inflection and therefore has the same slope at two different values of epicentral distance. The Herglotz-Wiechert method may then be applied to these travel times to obtain a velocity-depth distribution.
