Sunday’s 6.0 magnitude earthquake was the largest to hit the Northern California Bay area in 25 years. It sent more than 120 people to hospital and caused severe damage to numerous businesses. CCTV America’s Mark Niu reports from Napa.

According to the catastrophe modeler, EQECAT, all damage estimates of insured losses could top to $1 billion.

Even many businesses that believed their stores were in good order have been red-tagged unsafe due to badly hit neighbors.

“Until these buildings are deemed okay, I’m sure they have to do a little bit more work, then I can open up. But, from the looks of it, I probably won’t open up for a while,” said Rick Molinari, owner of Molinari Caffe, as he stood outside his coffee shop business.

Lucero Olive Oil, a local store, lost 90 percent of its inventory, and after a massive clean up effort, it is now back in business.

“Giant garbage cans, sweeping up glass and oil and vinegar. Keep cleaning up over the next few weeks as we go or the next few days and next week as we go but we’re back in business,” said owner David Gadlin.

Police are patrolling to make sure that people stay clear of dangerous buildings. They said there’s been no problem with looting so far.
