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 »

Fiber Optics Detect Crevasse Icequakes on Alpine Glacier

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 »
