Earthquakes and Tsunamis
Using low frequency hydrophones scientists and researchers can record undersea volcanoes and earthquakes. The mass of energy released is what’s known as thrust faulting. Thrust faulting happens when one tectonic plate dives under another. As the seismic energy from the earthquake spreads through the water it can set off a tsunami. Hydrophones that monitor for volcano, earthquake and tsunami sounds can be deployed in various ways. They can be attached to an underwater observatory, dropped into the water from ocean vessels, attached to a float, or anchored to the seafloor. Using these various deployment methods scientists are able to detect earthquakes that strike in the middle of the ocean.
