Twenty-five years after a big rumbler hit northern California, the San Francisco Bay area felt the earth move around them again Sunday morning.
Sunday's 6.0 earthquake was the strongest since the 1989 Loma Prieta quake.
The earthquake hit at 3:20 a.m. local time, rumbling just shy of 7 miles below the earth. The epicenter was close to Napa and about 30 miles northeast of San Francisco and 50 miles from the capital, Sacramento.
More than 100 Californians were hurt in the earthquake, which caused at least six major fires, a widespread power outage and building damage. Further away, the damage was mostly cosmetic. Closer to Napa, eyewitnesses report more major destruction to buildings.
People took to Twitter to post pictures both serious and sarcastic showing the earthquake damage.

The U.S. Geological Survey put out a "shake map" that shows both the epicenter, the star, and where the earthquake was most felt, shaded in light green.
The U.S. Geological Survey also put out an aftershock warning, saying there is about a 50 percent possibility of strong aftershocks 5.0 or larger in the next week. The chance of smaller aftershocks is ever higher.
