A new study published in the journal Science Advances changes our understanding of how volcanic arc lavas are formed, and may have implications for the study of earthquakes and the risks of volcanic eruption.Read More
When the ground in Japan started shaking on March 11, 2011, the Japanese, who are well accustomed to earthquakes, knew…Read More
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.
How coastal communities manage risks associated with major tsunamis is an issue of global importance following the devastating 2004 Indian…Read More
Kong, a 1990 graduate of the MIT/WHOI Joint Program in Oceanography/Applied Ocean Science and Engineering, was one of the first people in the world to learn the magnitude of the underwater earthquake off the coast of Indonesia.Read More
Since the great Indonesian earthquake and tsunami of December 26, 2004, policy-makers and scientists around the globe have been embracing a rare moment of public attention on the oceans, accelerating plans to create a comprehensive tsunami-warning network and to make citizens better prepared for the next massive wave. Another potent earthquake along the same fault on March 28, 2005, has increased that sense of urgency.Read More
In a study published Dec. 24, 2004, in the Journal of Geophysical Research, Woods Hole geologists Uri ten Brink and Jian Lin reported a heightened earthquake risk from the Septentrional fault zone, which cuts through the highly populated Cibao valley in the Dominican Republic.Read More

Potential landslides on the outer continental shelf and slope along the Mid-Atlantic coast could trigger tsunamis that might have devastating effects on populated coastal areas. In a paper published in the May 2000 issue of the journal Geology,Neal Driscoll of the Woods Hole Oceanographic Institution and colleagues Jeffrey Weissel of Columbia University??A?s Lamont-Doherty Earth Observatory and John Goff of the University of Texas at Austin say newly discovered cracks along the edge of the continental shelf could be an early warning sign that the seafloor is unstable in these areas.
