Residents in California's Napa Valley area awoke Sunday to a 6.0-magnitude earthquake that crumbled buildings, knocked products off of store shelves and did an estimated $500 million to $1 billion in insured losses according to catastrophe risk modeler Eqecat.

The quake, which lasted 18-20 seconds, ruptured gas mains and water lines, damaged building facades, and spawned numerous structural fires across the area. Windows in the air traffic control booth at the Napa Airport were blown out, and local vineyards experienced major damage to their wine and olive oil stocks.

According to the U.S. Geological Survey the quake hit around 3:30 a.m. local time on Sunday about six miles southwest of Napa, Calif. No fatalities have been reported, but more than 170 people were taken to local hospitals with injuries ranging from broken bones and respiratory or cardiac issues. There were also a number of less severe injuries from falling debris. Power outages ranged from 70,000 customers in Sonoma and Napa counties to several thousand in surrounding areas. Streets and bridges are undergoing safety inspections throughout the city as of Monday.
