Fiber Optics Detect Crevasse Icequakes on Alpine Glacier | Seismological Society of America

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 glaciers, especially as these cracks offer a pathway for meltwater to reach the rocky glacier bed to speed up the glacier’s mo…
