A small 3.1 magnitude earthquake about 50 miles southwest off the coast of Eureka rattled Humboldt County on Saturday morning, according to the United States Geological Survey.
The tremor, striking just after 9 a.m., was likely the latest in a series of aftershocks along the North Coast in recent months after a 6.4-magnitude quake on Dec. 20 that damaged many homes and left two people dead.
“We have had a lot of aftershocks in that area,” said Paul Caruso, a geophysicist with USGS. “We would expect those to continue, but we can’t predict how long that could last and how big they could be.”
A 5.4 aftershock hit the area on Jan. 1, followed by a 4.6 quake on March 22.
Residents in Eureka and Arcada reported feeling Saturday’s quake, which was about 6 miles deep, according to USGS. There were no immediate reports of damage or threat of a tsunami.
