California's wine country is assessing the damage following yesterday morning's 6.0-magnitude earthquake and the numerous aftershocks.
Dozens of homes and buildings across the Napa Valley are no longer safe to occupy, including an old county courthouse, where a 10-foot wide hole opened a view of the offices inside.
Scores were injured as the temblor knocked out power to thousands, caused gas and water lines to rupture and sparked fires around the city of Napa.
Queen of the Valley Medical Center in Napa reported treating 172 people in the emergency room. Twelve people were admitted, including an adult who remained in critical condition last night.
The quake was the largest to shake the San Francisco Bay Area since 1989.
