A system of deep-sea cables near Monterey Bay, California, is helping researchers identify seismic movement at the bottom of the sea. A team of researchers from Rice University and the University of California used the cables to record a 3.5-magnitude earthquake in Gilroy, California. They also used them to find a new fault system near the San Andreas Fault, which runs along the California shoreline. Researchers believe the technology could finally be used to outline lapse lines in undiscovered areas.
