The smoothing of seismological travel-time tables using cubic splines

DEPARTMENT OF APPLIED MATHEMATICS THE WEIZMANN INSTITUTE OF SCIENCE, REHOVOT, Israel

Abstract

The use of cubic-spline functions for the smoothing of seismological travel-times data is suggested. This smoothing method is compared with other methods used for that purpose. The final stages of the production of the Herrin P-tables are critically examined, and the use of cubic-spline functions for their smoothing is shown to improve the resulting table.
