Iran Press/America: The temblor, which hit around 12:10 p.m., was centered in the Pacific Ocean, about 24 miles west of Petrolia and 44 miles southwest of Eureka, according to USGS.
Multiple aftershocks with magnitudes in the 2.5 and 4.0 range are impacting the area, state officials say.
There were no immediate reports of any injuries or major damage.
The California Governor’s Office of Emergency Services is “actively monitoring” the situation, according to a tweet from the agency.
The quake’s preliminary magnitude was measured at 5.8 before it was upgraded by the Geological Survey a short time later.
Shaking was felt throughout the northern part of the state and as far south as the Bay Area, USGS’s website showed.
