Geoarchaeological evidence reveals a major M9.5 tsunamigenic earthquake in Chile
A new study published this week in Science Advances presents…
Mysterious global tsunami in 2021 caused by hidden M8.2 earthquake
Scientists have uncovered the source of a mysterious 2021 tsunami that sent waves around the globe in August 2021 when a magnitude 7.5 earthquake hit near the South Sandwich Islands. The epicenter was 47 km (29 miles) below the Earth’s surface — too deep…
World’s longest recorded earthquake lasted for 32 years
The devastating M8.5 earthquake that shook Sumatra, Indonesia, in 1861 was long believed to be a sudden rupture on a previously quiescent fault. However, new research showed that tectonic plates below the island had been slowly crashing against each other for 32…
Study reveals inner workings of slow-slip earthquakes
Slow-slip earthquakes have been detected at many earthquake hotspots in the world, including areas around the Pacific Ring of Fire, but it remains unclear as to how they are linked to the damaging quakes that take place there. In a new study, researchers at The…
Electromagnetic anomalies occurring before large earthquakes
A new study published in Earth, Planets and Space sheds new light on the electromagnetic anomalies occurring before large earthquakes. The research supports the hypothesis that fault rupture progresses just before an earthquake, and the invading gas is charged and…
Earthquakes and tsunamis from subduction zones more destructive than current estimates
Earthquakes and tsunamis from subduction zones might be more hazardous than current estimates, a new study suggests. Researchers from the University of New Mexico and the Nanyang Technological University developed a new method to assess the dangers represented by…
Study reveals mechanism of naturally occurring ‘earthquake gate’
A new study reveals the workings of an "earthquake gate" — a naturally occurring blocker that decides which quakes are allowed to grow into M8.0 or greater. "An earthquake gate is like someone directing traffic at a one-lane construction zone,"…
New technology detects long-hidden earthquakes
Scientists at the Stanford School of Earth, Energy, and Environmental Sciences described a new method for using artificial intelligence to detect millions of long-hidden small earthquakes or microquakes, providing possible hints about how earthquakes evolve. Big…
New insights show factors that trigger earthquakes
A new study by François Xavier Passelegue, a scientist at ENAC's Laboratory of Experimental Rock Mechanics (LEMR), has provided new insights into the origins of earthquakes, showing that the speed and intensity with which seismic waves cultivate after a…
San Andreas Fault earthquakes caused by deep underground forces
Scientists at the University of South California (USC) have detected that the earthquakes registered alongside California’s San Andreas Fault occur much deeper than previously understood. The previous knowledge of the fault indicated that earthquakes are…
