A 6.0 magnitude earthquake hit the Bay Area this morning, damaging buildings and roads and leaving tens of thousands without power.
The earthquake was reported at 3:20 a.m. about three miles northwest of American Canyon, according to the U.S. Geological Survey.
The U.S.G.S. also reported 2.5 and 3.6 magnitude aftershocks about four miles southwest of Napa at 5:01 a.m. and 5:47 a.m., respectively. Several smaller aftershocks have also been reported.
Following the incident, California Highway Patrol personnel visually inspected all roadways, overcrossings and bridges. As of noon today, damage was noted in the following locations:

Traffic control is in effect at those locations, but all roads are open and accessible to the general public. The CHP is asking for the public's help in detecting additional damaged locations. If you see roadway damage, call the CHP at our non-emergency line (1-800-TELL-CHP / 1-800-835-5247). If damage to the roadway could cause a collision, please call 9-1-1.
Many areas are without power, resulting in deactivated traffic signal lights. The CHP reminds the public that dysfunctional traffic signals must be treated as all-way stop signs. Please check carefully at each intersection before proceeding through.
Damage was reported to structures within the city of Napa. At this time, the Napa Police Department requests that people avoid the areas of damage, and to avoid entering Napa area if you have no urgent business there.
