Observation of Underwater Earthquakes by Using a Hydroacoustic Monitoring System

Abstract

Substantial advances in seismograph technology enable us to precisely and extensively monitor earthquakes occurring everywhere in the world, yet underwater tectonic events have remained insufficiently studied due to a dearth of seismic networks in the oceans. Hydroacoustic monitoring allows the detection and the precise location of small submarine earthquakes and volcanic activity. Furthermore, through hydroacoustic observation, we are able to examine cryogenic signals, which are closely associated with changes in the polar environment, baleen whale calls, and catastrophic tsunamis.etworks in the oceans.
