Slow motion precursors give earthquakes the fast slip

At a glacier near the South Pole, earth scientists have found evidence of a quiet, slow-motion fault slip that triggers strong, fast-slip earthquakes many...

Deep, slow-slip action may direct largest earthquakes and their tsunamis

Megathrust earthquakes and subsequent tsunamis that originate in subduction zones like Cascadia -- Vancouver Island, Canada, to northern California -- are some of the...

New model reveals previously unrecognized complexity of oceanic earthquake zones

Researchers from the University of Tsukuba applied seismic data from around the world to build a model of the 2020 Caribbean earthquake. Oceanic transform...

New fault zone measurements could help us to understand subduction earthquakes

A research team from the University of Tsukuba has conducted detailed structural analyses of a fault zone located in central Japan, with the aim...

Unusually shallow earthquake ruptures in Chinese fracking field

An unusually shallow earthquake triggered by hydraulic fracturing in a Chinese shale gas field could change how experts view the risks of fracking for...

How earthquake swarms arise

Earthquakes can be abrupt bursts of home-crumbling, ground-buckling energy when slices of the planet's crust long held in place by friction suddenly slip and...

Superheated rocks deep underground help explain earthquake patterns

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,...

Deep underground 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,...

The Le Teil earthquake provides new insights on seismic risk in...

On 11 November 2019, a magnitude 5 earthquake occurred near the village of Le Teil in the Rhône River Valley in southern France producing...

Machine learning unearths signature of slow-slip quake origins in seismic data

Combing through historical seismic data, researchers using a machine learning model have unearthed distinct statistical features marking the formative stage of slow-slip ruptures in...

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...

A new study led by McGill University has found that tectonic plates beneath the Earth's surface can show varying degrees of roughness and could...

New NASA radar looks to monitor volcanoes and earthquakes from space

Instead of looking up to the sky for bright bursts of fiery color, a research team spent Fourth of July 2018 peering down at...
