Over 80 people were treated at hospital and massive power outages were reported in North Bay area of San Francisco and around the city of Napa, after California was shaken by a 6.0 magnitude earthquake.
The 6.0 quake struck at 3:20 am (10:20 GMT), the US Geological Survey said. Its epicenter was 6 kilometers from American Canyon and 9 kilometers from the city of Napa, at a depth of 10.8 kilometers from the surface.
Residents of the cities of San Francisco, some 40 miles away, and Davis, just over 70 miles away, quickly took to Twitter reporting feeling the quake.
Three people – two adults and one child – sustained critical wounds. At least 87 people were treated for minor injuries at Napa hospital after the earthquake, the spokesperson told AP. Most patients have cuts, bumps, bruises, said Vanessa DeGier, spokeswoman for the hospital in Napa.
The quake caused six significant fires including a blaze at the Napa Valley mobile home park, where 4 trailers were completely destroyed, according to local firefighters.
“There’s collapses, fires,” said Napa Fire Capt. Doug Bridewel. “That’s the worst shaking I’ve ever been in.”
The city government said there were 50 gas main breaks and 30 water main leaks. Three historic buildings in Napa were also damaged, including the county courthouse, and at least two downtown commercial buildings were severely damaged.
At least 15,000 customers were left without power across Northern California, the utility provider Pacific Gas and Electric Company’s map showed following the massive quake.
The USGS initially measured the tremor as “moderate,” but then it was upgraded to “violent.” The immediate hours after the event saw at least five aftershocks measuring at 1.6 magnitude. Aftershocks of up to 5.0 magnitude may continue throughout the next week.
