An earthquake in New Jersey?

This morning, a 4.8 magnitude earthquake struck in New Jersey, sending tremors throughout the region. People in places entirely unused to shaking, including New York City, Boston, and Philadelphia, could feel it. Californians with relatives on the East Coast spent the morning scratching their heads. University of California, Riverside seismologist Abhijit Ghosh, who studies earthquake...

Study ties fracking to another type of shaking

New research confirms fracking causes slow, small earthquakes or tremors, whose origin was previously a mystery to scientists. The tremors are produced by the same processes that could create large, damaging earthquakes. Fracking is the high-pressure injection of fluids underground to extract oil and natural gas. Though it is typically done with wastewater, this study...

Massive Mexican earthquakes warn Southern Californians

"A pair of massive earthquakes in Mexico — 7.6 on Sept. 19 and 6.8 on Sept. 22 — have some in Southern California on edge, wondering whether the Golden State is next. Here, UC Riverside seismologist Abhijit Ghosh weighs in on the likelihood of more shakers, and how to prepare for them. Ghosh is an...

The thrust of the problem

Anew understanding of a fault that caused a deadly 7.8 magnitude earthquake can help scientists better predict where and when the next big one will hit. For decades, scientists have debated the structure of the Main Himalayan Thrust — the fault responsible for a 2015 earthquake that killed nearly 9,000 people, injured 22,000, and destroyed...

Making sense of a ‘7.1’

The fault underneath the town of Ridgecrest, California, has no name because scientists did not discover it until the 7.1 magnitude earthquake it produced on July 5. Now, Abhijit Ghosh, an associate professor of geophysics at UC Riverside, is racing to understand everything hecan about the unnamed fault to help officials prepare for the next...

Earthquake Risk Elevated with Detection of Spontaneous Tectonic Tremor in Anza Gap

"Scientists at the University of California, Riverside have detected spontaneous tectonic tremor — a signature of slow earthquakes deep below the earth’s surface — in the Anza Gap region of the San Jacinto Fault. Tectonic tremors are believed to increase the likelihood of a moderate to large, damaging earthquake occurring close to the earth’s surface...

Slow Earthquakes Occur Continuously in the Alaska-Aleutian Subduction Zone

"Seismologists at the University of California, Riverside studying earthquakes in the seismically and volcanically active Alaska-Aleutian subduction zone have found that “slow earthquakes” are occurring continuously, and could encourage damaging earthquakes." Read More

UCR Graduate Student Selected to Attend Geosciences Congressional Visits Day

"Manuel Mendoza, a master’s student at UC Riverside working with Abhijit Ghosh, assistant professor in the Department of Earth Sciences, was one of only two graduate students in the country to be selected by the Seismological Society of America (SSA) to receive travel grants to attend the 8th annual Geosciences Congressional Visits Day in Washington...
