Scientists have discovered that deep earthquake faults can heal themselves within hours, acting like “quick-set glue” after slow slip events.

A series of earthquakes rattled California’s Bay Area near Gilroy on Wednesday, according to the U.S. Geological Survey. The ...

When we think of earthquakes, we imagine sudden, violent shaking. But deep beneath the Earth's surface, some faults move in near silence. These slow, shuffling slips and their accompanying hum -- ...
