University of South Florida geoscientists have successfully developed and tested a new high-tech shallow water buoy that can detect the small movements and changes in the Earth’s seafloor that are often a precursor to deadly natural hazards, like earthquakes, volcanoes and tsunamis.

In a new study published in the Journal of Geophysical Research: Oceans, a journal of the American Geophysical Union, researchers explore how tsunamis impact shallow marine environments, also known as benthic environments, and the small, burrowing animals that dwell there.

The most populated central region of Chile could be vulnerable to large tsunamis generated by a deceptively moderate kind of earthquake that might be overdue, say scientists who have sorted out the source of an earthquake and tsunami that struck the area 287 years ago. The region is the same that trembled from a magnitude 6.9 earthquake on April 24.

A new study is challenging a long-held theory that tsunamis form and acquire their energy mostly from vertical movement of the seafloor. The finding validates an approach developed by researchers that uses GPS technology to detect a tsunami’s size and strength for early warnings.

Researchers have discovered a large concentration of sediment deposits at the end of Monterey Canyon, an underwater chasm beneath Monterey Bay, California. The sediment deposits are relatively young and may be more likely to catalyze underwater landslides than other sections of the canyon, according to the researchers who presented their discovery at the 2016 American Geophysical Union Fall Meeting.

A new study estimates the probability of a Magnitude 9+ earthquake in the Aleutian Islands—an event with sufficient power to create a mega-tsunami especially threatening to Hawai‘i. In the next 50 years, there is a 9 percent chance of such an event, according to researchers from University of Hawai‘i at Mānoa.

Tsunamis generated by earthquake faults off the Santa Barbara coast could pose a greater danger to the cites of Ventura and Oxnard than previously thought.

An 8.0-magnitude earthquake struck 70 kilometers west of Santa Cruz Island in the Solomon Islands Feb. 6. It triggered a tsunami that swept through tribal towns and wooden huts along a 20-kilometer stretch of coastline.

There’s a hole in the bottom of the ocean near Japan, the deepest ever drilled for science. It leads to the heart of one of the world’s most dangerous faults, the one that unleashed the 2011 Tohoku earthquake and tsunami, which devastated Japan’s east coast. The earthquake’s power astonished geologists, who didn’t think the fault was capable of such destruction.To find out why the quake was so massive, an international team drilled through more than 800 meters of rock, seven kilometers beneath the waves, to take the fault’s temperature.
