Hours before the 2018 eruption of Sierra Negra, the Galápagos Islands’ largest volcano, an earthquake rumbled and raised the ground more than 6 feet in…
New Supercomputer View of Seismic Hazards: Simulating 800,000 Years of California Earthquake History to Pinpoint Risks
Supercomputer-powered framework developed by SCEC provides new view of seismic hazard. Massive earthquakes are, fortunately, rare events. But that scarcity of information blinds us in…
Stanford AI Technology Detects Hidden Earthquakes – May Provide Warning of Big Quakes
New technology from Stanford scientists finds long-hidden quakes, and possible clues about how earthquakes evolve. Tiny movements in Earth’s outermost layer may provide a Rosetta…
Innovative New Model Reveals Previously Unrecognized Complexity of Oceanic Earthquake Zones
University of Tsukuba researchers have developed a state-of-the-art model, which has revealed major complexity in rupture processes even in simple oceanic faults. Researchers from the…
Largest Earthquakes and Their Tsunamis May Be Directed by Deep, Slow-Slip Action
Megathrust earthquakes and subsequent tsunamis that originate in subduction zones like Cascadia — Vancouver Island, Canada, to northern California — are some of the most…
Seismic Ocean Thermometry: Noise From Deep-Sea Earthquakes Provides New Way to Measure Ocean Warming
Using soundwaves cast from seafloor earthquakes, researchers demonstrate a new take on a largely abandoned way to measure ocean warming worldwide — seismic ocean thermometry….
Strange Precariously Balanced Rocks Provide Earthquake Forecasting Clues
Precariously balanced rocks (PBRs) are formations found throughout the world where a slender boulder is balanced precariously on a pedestal boulder. They form as blocks…
Deep Underground “Rock-Melting” Forces Explain Quakes on San Andreas Fault
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…
Rare ‘Boomerang’ Earthquake Tracked by Scientists in the Ocean for the First Time
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…
