The study says that stormquakes are actually a fairly common occurrence, but they just sounded like seismic background noise and went undetected.

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
New Zealand’s geologic hazards agency reported this week an ongoing, “silent” earthquake that began in January is still going strong.…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.
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
Jian Lin came of age in an era of both geological and political seismic shifts in China, experiencing the deadliest earthquake in the 20th century in Tangshen in 1976 and the Cultural Revolution in the 1970s. Then he immigrated to America and came full circle in 2005 to become the first U.S. scientist to co-lead a Chinese deep-sea research cruise.Read More

The earthquakes were coming fast and frequent, as many as 50 to 70 an hour. On the morning of Sunday, Feb. 28, undersea hydrophones began detecting the most intense swarm of earthquakes to occur in the last three years along the Juan de Fuca Ridge, about 200 miles off the Pacific Northwest coast.Read More
If any good has come from the recent devastating earthquakes off Sumatra, it is that they are providing scientists with unprecedented clues to understanding how these large undersea earthquakes occur and how they create tsunamis.Read More
