Map of the Cascadia subduction zone. Megathrust earthquakes and subsequent tsunamis that originate in subduction zones like Cascadia — Vancouver Island, Canada, to northern California — are some of the most severe natural disasters in the world. Now a team of geoscientists thinks the key to understanding some of these […]

Credit: Johanna Buguet/Unsplash Scientists examining the effects of a megathrust earthquake in the Pacific Northwest say tall buildings across Metro Vancouver will experience greater shaking than currently accounted for by Canada’s national seismic hazard model. The region lies above the Georgia sedimentary basin, which is made up of layers of […]

An artist’s rendering of undersea earthquake waves.

The method, which they tested in the East Indian Ocean and where they uncovered a decadal […]

A swarm of 91 earthquakes rattled the Yellowstone National Park region in just 24 hours on Thursday, according to the United States Geological Survey. The quakes trembled southwest of Yellowstone Lake between Heart Lake and West Thumb. Although the area is one of the most seismically active regions in the […]

Rock-melting forces occurring much deeper in the Earth than previously understood appear to drive tremors along a notorious segment of California’s San Andreas Fault, according to new USC research that helps explain how quakes happen. The study from the emergent field of earthquake physics looks at temblor mechanics from the bottom up, […]

The 600 kilometer-long (370 mile) faultline on the boundary of the Eurasian and Pacific tectonic plates beneath the country’s South Island produces infrequent but significant earthquakes. In the line […]

Reconstructed image of the fracture zone. Credit: Hicks et al. Scientists observed a ‘boomerang’ earthquake along Atlantic Ocean fault line, providing clues about how they could cause devastation on land. Earthquakes occur when rocks suddenly break on a fault – a boundary between two blocks or plates. During large earthquakes, […]

Credit: CC0 Public Domain A new study suggests that last year’s Ridgecrest earthquakes increased the chance of a large earthquake on California’s San Andreas fault. The study, published in the Bulletin of the Seismological Society of America on Monday, says there is now a 2.3% chance of an earthquake of magnitude 7.5 […]
