The earthquake sent 120 people to Queen of the Valley Medical Center in Napa, where officials set up a triage tent to handle the influx. Hospital CEO Walt Mickens says most had cuts, bumps and bruises received either in the quake, when they tried to flee their homes or while cleaning up. Three people were admitted with broken bones, and two for heart attacks.

Napa City Manager Mike Parness says 15 to 16 buildings are no longer inhabitable after Sunday's magnitude-6.0 earthquake, and there is only limited access to numerous other structures, mostly ones with broken windows. Officials say they are still assessing buildings in the area.
