A significant earthquake rocked the San Francisco Bay area early Sunday morning.

According to the United States Geological Survey, the 6.0 magnitude earthquake struck 51 miles southwest of Sacramento close to Napa Valley. The earthquake hit about 6.7 miles deep, which constitutes as a shallow earthquake. According to the USGS, it's the largest earthquake in the area since the Loma Prieta quake in 1989, a 6.9 magnitude quake. 

Here's the map of the earthquake's epicenter:

Users on Twitter reported power outages in Napa, Sonoma, and other spots throughout the area. The California Highway Patrol in Santa Rosa said there were widespread power outages in the area, including multiple power poles down. The CHP said there was no visible damage on overpasses and bridges in the area.
