The San Francisco Bay Area of California was struck by a 6.0 magnitude earthquake early Sunday morning.

At about 3:30 a.m. residents in the area felt the tremors. According to the US Geological Survey this is the largest earthquake to hit the Bay Area since the 6.9 magnitude quake that hit in 1989.

According to the Los Angeles Times, at least 70 injuries have been reported. Many are being treated and released, while some have been admitted for more serious injuries.

The extent of the damages are still unknown, while local authorities are checking all bridges for cracking and other buildings for structural damage. Napa Fire Captain Doug Bridewell said, "There's collapses, fires….That's the worst shaking I've ever been in,” reported Fox News.

More than 40,000 people have reported being without power, while many large roadways are suffering severe damage that could cause flat tires to any motorist attempting to drive on them.

Residents still have to be wary of any remaining aftershocks. Many residents have stated that they haven’t felt any, but two have been reported so far. However, chances of a strong aftershock are down to 54% according to the National California Seismic System.
