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

Margaret Mangan didn't sleep well in the weeks following the Ridgecrest, Calif., earthquakes. The July shaking triggered a swarm of smaller tremors in the...

Underwater telecom cables make superb seismic network

Fiber-optic cables that constitute a global undersea telecommunications network could one day help scientists study offshore earthquakes and the geologic structures hidden deep beneath...

New technology developed to improve forecasting of Earthquakes, Tsunamis

University of South Florida geoscientists have successfully developed and tested a new high-tech shallow water buoy that can detect the small movements and changes...

Evidence of two quakes extends rupture history in Grand Tetons National...

Hand-dug trenches around Leigh Lake in Grand Teton National Park in Wyoming reveal evidence for a previously unknown surface-faulting earthquake in along the Teton...

Geoscientists hope to make induced earthquakes predictable

University of Oklahoma Mewbourne College of Earth and Energy assistant professor Xiaowei Chen and a group of geoscientists from Arizona State University and the...

Earthquake impact can be affected by seasonal factors, historical study shows

The season that an earthquake occurs could affect the extent of ground failure and destruction that the event brings, according to a new look...

Studying the snowmelt episodes of a Pyrenean river with a seismometer

A team of researchers at Institute of Earth Sciences Jaume Almera of the Spanish National research Council (ICTJA-CSIC) have analysed the seismic signals generated...

Distinguishing earthquake foreshocks and aftershocks

Up to now, there was no way of predicting whether a powerful earthquake was likely to be followed by one of even greater magnitude....

Role of earthquake motions in triggering a ‘surprise’ tsunami

In newly published research, an international team of geologists, geophysicists, and mathematicians show how coupled computer models can accurately recreate the conditions leading to...

Understanding the link between fracking and earthquakes

Researchers studying hydraulic fracturing have answered a longstanding question over how the practice can sometimes cause moderate earthquakes and may be able to use...

Earthquake study casts doubt on early warnings but hints at improved...

A recent study has investigated around 100,000 localized seismic events to search for patterns in the data. University of Tokyo Professor Satoshi Ide discovered...

Underground links between quakes and eruptions of Japan’s biggest active volcano

The threat of explosive volcanic eruptions looms over many cities around the world. Earthquakes, another major geological hazard, are known to have some relationships...

Rock scratches hint at future quakes

Curved scratches in rock faces may give clues to where big quakes could strike next, a study led by Victoria University of Wellington Master's...

Predicting the strength of earthquakes

Scientists will be able to predict earthquake magnitudes earlier than ever before thanks to new research by Marine Denolle, assistant professor in the Department...

Predicting earthquake hazards from wastewater injection

A byproduct of oil and gas production is a large quantity of toxic wastewater called brine. Well-drillers dispose of brine by injecting it into...

Faint foreshocks foretell California quakes

New research mining data from a catalog of more than 1.8 million southern California earthquakes found that nearly three-fourths of the time, foreshocks signalled...
