Natural Fluid Injections Triggered Cahuilla Earthquake Swarm Machine-learning algorithm helps geoscientists create a 3-D picture of a fault zone, generating new insight into seismic processes….
University of Missouri engineers said their material has both civilian and military applications. Shake, rattle and roll. Even though they are miles from the epicenter…
Earthquakes that occur more than 300 kilometers below the Earth are poorly understood. UC Davis geophysicist Magali Billen modeled stresses in a sinking tectonic plate…
At the regional level and worldwide, the occurrence of large shallow earthquakes appears to follow a mathematical pattern called the Devil’s Staircase, where clusters of…
Machine learning technique may help scientists more accurately map vast underground geologic structures. Over the last century, scientists have developed methods to map the structures…
Lightning — one, two, three — and thunder. For centuries, people have estimated the distance of a thunderstorm from the time between lightning and thunder….
Nearly 40 years ago, analog data tapes faithfully recorded intense seismic activity in the two months before the historic eruption of Mount St. Helens in…
‘Melting rock’ models predict mechanical origins of earthquakes with friction dropping as rocks slide past one another with greater speed. Engineers at Duke University have…
Scientists use satellite data to help response agencies identify damaged areas. Days after a 6.4-magnitude earthquake rocked Puerto Rico, followed by hundreds of aftershocks, the…
This past week, southeast France was hit by a magnitude 5 earthquake with tremors felt between Lyon and Montélimar. The Copernicus Sentinel-1 radar mission has…
University of California, Riverside research sheds new light on earthquake that killed 9,000 people. A new understanding of a fault that caused a deadly 7.8…
A recent study investigated around 100,000 localized seismic events to search for patterns in the data. University of Tokyo Professor Satoshi Ide discovered that earthquakes…
The threat of explosive volcanic eruptions looms over many cities around the world. Earthquakes, another major geological hazard, are known to have some relationships with…
New seismic data provide structural basis for strong earthquakes that strike at both ends of the Pacific Northwest fault zone. With four years of data…
Geophysicists have obtained detailed three-dimensional images of a dangerous megathrust fault west of Costa Rica where two plates of the Earth’s crust collide. The images…
Scientists presented evidence tying the disposal of wastewater from shale gas hydrofracking to an increased occurrence of earthquakes. The scientists presented their findings at the…
Last year, the surprise 5.8-magnitude earthquake that struck central Virginia was actually worse than previously thought. Detailed analyses of the ground motions triggered by the…
A new study from the Australian National University examines defects in rocks found below the earth’s surface in an attempt to better understand how seismic…
