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...

Sediments may control location, magnitude of megaquakes

The world's most powerful earthquakes strike at subduction zones, areas where enormous amounts of stress build up as one tectonic plate dives beneath another....

‘Fossil earthquakes’ offer new insight into seismic activity deep below Earth’s...

A major international study has shed new light on the mechanisms through which earthquakes are triggered up to 40km beneath the earth's surface. While such...

Shifts in deep geologic structure may have magnified great 2011 Japan...

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...

Seismic biomarkers in Japan Trench fault zone reveal history of large...

In the aftermath of the devastating Tohoku-Oki earthquake that struck off the coast of Japan in March 2011, seismologists were stunned by the unprecedented...

Researchers find evidence to explain behavior of slow earthquakes

A team of researchers at the University of Ottawa has made an important breakthrough that will help better understand the origin and behavior of...

A new method for dating ancient earthquakes

Constraining the history of earthquakes produced by bedrock fracturing is important for predicting seismic activity and plate tectonic evolution. In a new study published...

Magnitude of Great Lisbon Earthquake may have been lower than previous...

The magnitude of the Great Lisbon Earthquake event, a historic and devastating earthquake and tsunami that struck Portugal on All Saints' Day in 1755,...

The ‘slow earthquakes’ that we cannot feel may help protect against...

Earthquakes are sudden and their shaking can be devastating. But about 20 years ago, a new type of earthquake was discovered. We cannot feel...

Analyzing seismic patterns to forecast the magnitude of the largest earthquake...

Earthquakes can have devastating impacts on communities all around the world. They strike without warning, often resulting in large fatalities. Since the aftershocks that...

California is famous for earthquakes, wildfires and Volcanoes
