SUBMARINE VOLCANIC ERUPTIONS RECENTLY LOCATED IN THE PACIFIC BY SOFAR HYDROPHONES

Abstract

Five sources of underwater sound having volcanic characteristics have been located in the Pacific Ocean by means of the Pacific Missile Range sofar hydrophone network. Two are in the Mariana Islands, one in the Nanpo Shoto, one in the Aleutian Islands, and one at the southeast end of the Austral Seamounts. The sounds range in duration from a few seconds (explosive) to weeks (periodic low rumblings). Sonagrams of some of these events show multiple bands as do those of underwater explosions.
