Unexpectedly Deep Seismic Activity Found Along California Fault

In Southern California, scientists listening to rumblings deep underground found seismic activity at deeper-than-expected levels, and it may signal new earthquake extremes, according to a new study. In order to better see these so-called micro signals, a group of researchers temporarily deployed detectors along the Newport-Inglewood fault (NIF), which stretches nearly 50 miles (80 kilometers), from Culver City to Newport Beach, in Southern California. "It's very helpful for us to do these kinds
