This article was published in Nature magazine, and highlights breakthrough research that uses the fibers in the Digital 395 project (California Broadband Cooperative) to detect, measure and report in real time, earthquakes anywhere along its 600-mile length from Barstow, CA to Reno, NV. It’s a remarkable innovation that was spearheaded by scientists at Caltech, who asked the head of CBC, Michael Ort, if they could use dark fibers for their experiments after the Ridgecrest earthquake a few years back.

The break of earthquake asperities imaged by distributed acoustic sensing - Nature
Distributed acoustic sensing technology is utilized to image four high-frequency rupture subevents of the 2021 Antelope Valley, California, earthquake; the results indicate that the subevents are due to the breaking of fault asperities.
