The strongest earthquake to hit the Bay Area since the 6.0 that rocked Napa on Sunday struck early Tuesday morning, along with four other aftershocks.
According to the U.S. Geological Survey, the earliest and largest of the four rumbles hit just after 5:30 a.m. Tuesday morning, when a 3.9 earthquake hit just northwest of American Canyon.
That quake was followed by a smaller 2.7 at virtually the same location, just a couple of minutes later, then a 2.8 around 6:15 a.m.
A 3.0 magnitude earthquake hit Napa at 6:45 a.m., followed by a 2.5 just before 11 a.m.
According to PG&E, all power in the city of Napa has been restored to its 70,000 customers as of Monday. They will be conducting courtesy gas safety checks at homes and businesses throughout the impacted area.
