Some Signals of Seismic Origin Received at Pacific Sofar Stations.
Abstract
It is not unusual for Sofar stations to receive signals from sources other than Sofar bombs, and it is well-known that some of these signals arise from seismic disturbances. The purpose of this memorandum is to present the data on signals from three recent disturbances which had somewhat unique features. These three events were the September 1952 eruption of Myojin Reef, a marine volcano located approximately 200 nautical miles south of Tokyo; the Tulare Valley earthquake 21 July 1952, and an earthquake of similar magnitude which occurred off the coast of Oregon on 20 August 1952.
