On supposed regional variations in travel times*

Abstract

An investigation of the Tango earthquake of March 7, 1927, shows that travel times for P observed in that shock agree within the limits of error of one or two seconds with the travel times found for other earthquakes and that thus far there is no indication of differences beyond the limits of observational errors between the travel-time curves of earthquakes in different regions. This statement, however, does not include the travel times to short epicentral distances of a few degrees found in various regions which are influenced by the local structures in those regions, and especially not to the travel times found from waves which have traversed only the uppermost parts under the Pacific Ocean.
