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

摘要

U.S. Navy hydrophone arrays (SOSUS) record signals in a range of frequencies thatincludes 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.
