In January and February 2020, scientists on R/V Atlantis explored hydrothermal vents on the Cayman Rise. They used the remotely operated vehicle Jason to get an up-close view of the vents and life around them. The vents lie on a seismically active part of the seafloor known as a mid-ocean ridge. Deep-sea shrimp swarm the vents, feeding on microbes that live on chemicals flowing from the vents. While they were there, a magnitude 4.7 earthquake struck just 100 miles away. Scientists will now be able to study how seismic activity affects hydrothermal vents and the life around them.Read More
Nearly 3,000 feet (900 metres) below the surface of Monterey Bay, a network of deep sea cables helps scientists to study marine life.
The study says that stormquakes are actually a fairly common occurrence, but they just sounded like seismic background noise and went undetected.

One of the most dangerous faults in North America is the Pacific Northwest’s Cascadia fault – an offshore, subduction zone fault capable of producing a magnitude 9 earthquake that would damage Portland, Tacoma, Seattle, and Victoria, British Columbia, and generate a large tsunami. Yet there are currently no instruments installed offshore, directly above the fault, for measuring the strain that is currently building up along the fault.
But a recent $1 million grant from The W. M. Keck Foundation to scientists at the Woods Hole Oceanographic Institution (WHOI) will change that. An interdisciplinary project led by WHOI geologist Jeff McGuire, an expert in global earthquake seismology and geodesy, and John Collins, director of WHOI’s Ocean Bottom Seismometer Lab, will build and install the first seafloor geodesy observatory above the expected rupture zone of the next great Cascadia earthquake.
JapanÃÂs recent magnitude 9.0 earthquake, which triggered a devastating tsunami, relieved stress along part of the quake fault but also has contributed to the build up of stress in other areas, putting some of the country at risk for up to years of sizeable aftershocks and perhaps new main shocks, scientists say.Read More
While JapanÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂs 9.0-magnitude earthquake and accompanying tsunami represent a devastating natural disaster for the countryÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂs residents, scientists should also seize upon the massive temblor as an important learning tool for future quakes around the world, including the Pacific Northwest coast of the United States, according to experts from the Woods Hole Oceanographic Institution (WHOI).Read More
Researchers analyzing the May 2008 Wenchuan earthquake in China?s Sichuan province have found that geological stress has significantly increased on three major fault systems in the region. The magnitude 7.9 quake on May 12 has brought several nearby faults closer to failure and could trigger another major earthquake in the region.Read More
Many earthquakes in the deep ocean are much lower in magnitude than expected. Geophysicists from the Woods Hole Oceanographic Institution (WHOI) have found new evidence that the fragmented structure of seafloor faults and previously unrecognized volcanism may be dampening the effects of these quakes.Read More
