(CNN) ––
A 6.2 magnitude earthquake off the coast of northern California shook a wide swath of the state shortly after noon local time, according to data from the US Geological Survey (USGS, for its acronym in English).
The quake occurred near Cape Mendocino, near Humboldt County, with reports of people feeling it as far away as San Francisco and Chico, California.
"It was slow at first, but then it really felt like it," Humboldt County Sheriff William Honsal told CNN.
"We haven't had an earthquake like this since 2010."
California's earthquake early warning system worked for those who signed up for alerts on their mobile devices.
Honsal estimates that he received the alert 10-15 seconds before he felt the ground begin to shake.
Humboldt County Emergency Services is currently assessing the damage.
But, they have had no reports of injuries or catastrophic damage.
Some minor damage to buildings has been found so far, including broken glass, Honsal said.

The California Office of Emergency Services "actively watches" and "coordinates closely with its local peers in the region to protect communities from any secondary impacts," the agency tweeted.
Humboldt County is sparsely populated, with only about 135,000 residents spread over approximately 10,300 square kilometers.
The area is near the California-Oregon border, about 434 kilometers north of San Francisco.
Several aftershocks have been detected since the initial earthquake, but a tsunami is not expected at this time, according to the sheriff's office.
