(Newser) – A 5.7 magnitude earthquake rattled nerves in southern California yesterday but didn't cause any injuries or serious damage. The quake—part of a swarm of dozens of aftershocks from April's Baja California quake—could be felt throughout Los Angeles County and caused a brief interruption in a San Diego Padres home game, the Los Angeles Times reports.

Experts say the long series of aftershocks from the April quake is a result of the earth's crust re-adjusting. "This is a big aftershock to the Easter Sunday quake, so it has all the dangers of any quake this size," a seismologist tells the San Diego Union-Tribune. "This is causing aftershocks of its own. Within the first 10 minutes of the quake we had 10 aftershocks measuring 3.0 or larger."
