A 6.0-magnitude earthquake struck Northern California early Sunday, the U.S. Geological Survey said.

It was the strongest to hit the Bay Area since 1989, when a quake struck during the World Series.

Sunday's earthquake struck 4 miles northwest of American Canyon, 6 miles southwest of Napa, and 9 miles southeast of Sonoma, according to the USGS.

There were some local reports of injuries, and 15,000 customers in and around Sonoma, Napa, and Santa Rosa lost power, according to Pacific Gas and Electric Company.

A water main ruptured in downtown Napa and a handful of structural fires broke out, according to the Napa city fire department.

CNN affiliate KTVU reported a church in Vallejo was heavily damaged and lost its bell tower.

Wine country hit

"I've got a lot of broken wine, being here in Napa," said Emily Massimi, who was woken up by the quake. "We tend to collect wine, so I have wine all over my kitchen, and glass, and pictures off the wall and books off of bookshelves," she told CNN.

At Silver Oak Winery, owner David Silver spent the morning cleaning up hundreds of broken wine bottles that fell off the shelves.

"Those bottles were very unique," he said. They were part of his private collection and worth hundreds of dollars. "It's a tragedy, but it's nothing we can't overcome." Silver said he plans to open the winery today.

The quake jolted downtown Napa resident Karen Lynch. "The refrigerator flew open and all the food fell out," she told CNN.

"It was not like other quakes we have felt," Lynch said. "This was a violent quake, jolting us to and fro."

There have been two aftershocks so far, according to the USGS, one registering at 2.5 and the other a 3.6 magnitude
