Hydroacoustic Arrays for Seismic Detection, Location and Discrimination: A Comparison With Land-based Seismic Arrays and Networks

Abstract

U.S. Navy hydrophone arrays (SOSUS) record signals in a range of frequencies that includes earthquake and explosive sources as well as those relevant to submarine detection, for which they were designed. In the Norwegian Sea we compared recordings of acoustic arrivals on SOSUS with seismic recordings at the arrays on land in Norway. We also studied seismic activity along the spreading centers between Iceland and Svalbard in an attempt to discern any difference in levels of seismicity associated with different sections of the ridge system.
