Proposed use of the T phase in tsunami warning systems*

Abstract

A STRIKING correlation between the occurrence of a short-period earthquake phase (T phase) traveling through the ocean with the speed of sound in sea water and the occurrence of tsunamis has been observed. The characteristics of the T phase are described and the data upon which the correlation is based are presented. Although further study is needed, the evidence at hand warrants the inclusion of instruments suitable for recording the T phase in tsunami warning systems. It is quite possible that SOFAR listening stations would be valuable adjuncts in the detection of tsunami-producing earthquakes since they offer the best means of recording the T phase.
