An earthquake in New Jersey? Tracie Ventimiglia Thu, 04/11/2024 - 11:10 More News Jules Bernstein April 05, 2024

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 physics, explains what happened.

Study ties fracking to another type of shaking

Study ties fracking to another type of shaking Tracie Ventimiglia Mon, 11/13/2023 - 14:27 More News Jules Bernstein August 10, 2023

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 examined data from fracking with liquid carbon dioxide. The process pushes carbon underground and keeps it from trapping heat in Earth’s atmosphere.

Massive Mexican earthquakes warn Southern Californians Mayra Gandarilla Fri, 10/21/2022 - 11:14 More News Jules Bernstein September 26, 2022

"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 associate professor of geophysics in the Department of Earth and Planetary Sciences. His work is broadly focused on understanding the physics of earthquakes, the processes that control them, and their associated hazards."

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 600,000 homes in Gorkha, Nepal. This fault is a direct result of ongoing collision between two tectonic plates — the Indian and Eurasian – that gives rise to the Himalayas.

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 big shake.

"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 by altering the stress along the fault."
