On Sunday, August 9, a magnitude-5.1 earthquake struck North Carolina, surprising the east coast of the United States. Not to be left out, early Monday morning, southern California hosted an earthquake swarm of its own. These mostly small temblors began with a magnitude-3.2 earthquake at 6:33 a.m., with the largest magnitude-4.6 event reported at 8:56 a.m. None of these quakes nucleated along the San Andreas Fault.

For the rest of the story, head to Temblor.
