Rare ‘boomerang’ earthquake observed along Atlantic Ocean fault line

Scientists have tracked a 'boomerang' earthquake in the ocean for the first time, providing clues about how they could cause devastation on land. Earthquakes occur...

What factors influence the likelihood of fracking-related seismicity in Oklahoma?

The depth of a hydraulic fracturing well in Oklahoma, among other factors, increases the probability that fracking will lead to earthquake activity, according to...

COVID-19 lockdown caused 50 percent global reduction in human-linked Earth vibrations

The lack of human activity during lockdown caused human-linked vibrations in the Earth to drop by an average of 50% between March and May...

Typhoon changed earthquake patterns

The Earth's crust is under constant stress. Every now and then this stress is discharged in heavy earthquakes, mostly caused by the slow movement...

How water in the deep Earth triggers earthquakes and tsunamis

In a new study, published in the journal Nature, an international team of scientists provide the first conclusive evidence directly linking deep Earth's water...

Natural fluid injections triggered Cahuilla earthquake swarm

A naturally occurring injection of underground fluids drove a four-year-long earthquake swarm near Cahuilla, California, according to a new seismological study that utilizes advances...

New clues to deep earthquake mystery

A new understanding of our planet's deepest earthquakes could help unravel one of the most mysterious geophysical processes on Earth. Deep earthquakes -- those at...

New model to accurately date historic earthquakes

Three earthquakes in the Monterey Bay Area, occurring in 1838, 1890 and 1906, happened without a doubt on the San Andreas Fault, according to...

New study finds connection between fault roughness and the magnitude of...

On March 11, 2011, a magnitude 9 earthquake struck under the seabed off Japan -- the most powerful quake to hit the country in...

Sinking sea mountains make and muffle earthquakes

Subduction zones -- places where one tectonic plate dives beneath another -- are where the world's largest and most damaging earthquakes occur. A new...

Researchers develop new explanation for destructive earthquake vibrations

Earthquakes produce seismic waves with a range of frequencies, from the long, rolling motions that make skyscrapers sway, to the jerky, high-frequency vibrations that...

Source of Indonesian earthquakes and tsunamis located

Devastating historical earthquakes and tsunamis in Indonesia can be traced to a recently discovered submarine extensional fault system, where sediment slumping along the fault...
