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

Better Understanding Post-Earthquake Fault Movement

"Preparation and good timing enabled Gareth Funning and a team of researchers to collect a unique data set following the 2014 South Napa earthquake that showed different parts of the fault, sometimes only a few kilometers apart, moved at different speeds and at different times. Aided by GPS measurements made just weeks before the earthquake...

Double Dose of Bad Earthquake News

"A team of researchers, including one from the University of California, Riverside, has discovered that earthquake ruptures can jump much further than previously thought, a finding that could have severe implications on the Los Angeles area and other regions in the world. The scientists found that an earthquake that initiates on one thrust fault can...

Annual Great California ShakeOut earthquake drill

"Faculty, staff and students at the University of California, Riverside will join 10 million people expected to participate in the annual Great California ShakeOut earthquake drill on Thursday, Oct. 15 at 10:15 a.m. The approximately two-minute drill is a voluntary exercise as a first response to a simulated magnitude 7.8 earthquake along the southern San...

Seismic Experiment in Alaska Could Shed Light on Slow Earthquakes

"An earthquake expert at the University of California, Riverside is leading a team of seismologists and volcanologists to conduct an experiment in Alaska that will record a variety of seismic events in that state. The experiment will also help better describe the characteristics of the Alaska-Aleutian subduction zone, one of the most seismically active regions...

Geologists Simulate Deep Earthquakes in the Laboratory

"More than 20 years ago, geologist Harry Green , now a distinguished professor of the graduate division at the University of California, Riverside, and colleagues discovered a high-pressure failure mechanism that they proposed then was the long-sought mechanism of very deep earthquakes (earthquakes occurring at more than 400 km depth). The result was controversial because...

Scientists "Haven't Figured Out" IE Quake Swarm

"A series of small earthquakes in the Inland Empire has UC Riverside geologist Dr. Gareth Funning struggling to identify just what they are. Jacob Rascon reports for the NBC4 News at 6 p.m. on April 24, 2012." Read More

NASA Science on the Road: Creeping Faults in California

*/ "The annual gathering of Earth and space scientists in San Francisco at the American Geophysical Union meeting draws thousands of researchers, including many involved with NASA research. Gareth Funning of the University of California-Riverside talks about his work monitoring "creeping faults" in the Bay area. His NASA-sponsored project enlists high school students to document...
