FERNDALE, Humboldt County (CBS SF) — An 5.8 magnitude earthquake has hit a coastal area of Northern California.

The quake hit just after 1:00 p.m. about 40 miles southwest of Eureka and 25 miles southwest of Ferndale, according to the U.S. Geological Survey. It was originally measured as a 5.1 magnitude earthquake then upgraded it to a 5.8 before dropping it back to 5.7.

“It felt like a small rolling quake here,” said Pam Cahill, who lives north east of the epicenter in Arcata. “I normally lock all the cabinets for this kind of thing but I didn’t have them locked. Still, nothing fell out.”

Two aftershocks in the same area measuring 3.3 and 2.6 magnitude struck withing 16 minutes of the earthquake.

There was no tsunami warning issued and no immediate reports of damage or injuries.
