Advancing earthquake science worldwide
16 April 2025—When Julian Lozos visited the site of the 2019 Ridgecrest earthquakes two days after the event, he noticed something strange. Pebble- to boulder-sized rocks clearly had been moved by the earthquakes—but there were no signs of dragging or shearing on the desert ground. He wasn’t the only one… Continue Reading Strong Shaking at Fault Stepover Has Rocks—Briefly—Defying Gravity
16 April 2025—Researchers are combining data on earthquake shaking intensity, crowdsourced traffic data from the Waze navigation app and police crash reports to find out if car crashes are more likely during seismic events. So far, the data are too sparse to draw much of a broad conclusion, although the… Continue Reading Do Earthquakes Affect Car Crashes in the United States?
16 April 2025—In places where earthquakes rupture the Earth’s surface, scientists often try to predict the location of these future fault ruptures based on the geological fault traces created in past earthquakes. But how accurate are these fault traces in predicting the next rupture location? At the Seismological Society of… Continue Reading How Well Do Mapped Tectonic Faults Predict the Location of Surface Rupture in the Next Earthquake?
15 April 2025—Fiber optic cable deployed on a Swiss glacier detected the seismic signals of crevasses opening in the ice, confirming that the technology could be useful in monitoring such icequakes, according to a report at the Seismological Society of America’s Annual Meeting. Crevassing is important to the stability of… Continue Reading Fiber Optics Detect Crevasse Icequakes on Alpine Glacier
15 April 2025—The 28 March magnitude 7.7 Mandalay, Burma (Myanmar) earthquake caused widespread and severe damage in Myanmar and neighboring countries such as Thailand, with more than 5,000 casualties now confirmed. At the Seismological Society of America’s Annual Meeting, researchers from around the globe shared early insights into the earthquake’s… Continue Reading Seismologists Share Early Analyses of Myanmar Earthquake
11 April 2025—Rebecca Colquhoun liked math and science in school but wasn’t sure what kind of career that might launch. Should they go into physics? Chemistry? Computer science? “I was looking for something that was sort of a mixture, so I could put off deciding for a while longer,” Colquhoun… Continue Reading At Work: Rebecca Colquhoun
