Abstract

A short-period arrival on records of the Bermuda-Columbia Seismograph Station is identified as the T phase. The path of propagation consists of land paths up to 51° preceding 14° of water path. It is shown that the travel time of this phase can be accounted for if the energy travels as the P phase over the land path and the T phase over the ocean path. Background noises in the Sofar channel do occasionally arise from earthquakes as much as several thousand miles inland.
