Officials at Diablo Canyon Power Plant say the plant declared an Unusual Event after the 5.3 magnitude earthquake early Sunday morning.
USGS says the epicenter was northwest of King City.
PG&E says they declared the Unusual Event after the earthquake was felt in the plant's control room.
They say there are four emergency classifications, which are established by the Nuclear Regulatory Commission (NRC), and an Unusual Event is the lowest of the four.
They declared the Unusual Event following protocols that have been set by the NRC.
The protocols also include notifying state and community partners.
Officials say Units 1 and 2 are safely operating at 100 percent power and there was no impact on plant operations.
