The U.S. Geological Survey reports that Humboldt County California was struck by a 5.7 magnitude earthquake Wednesday afternoon.

The quake’s epicenter was underwater about 40 miles southwest of Eureka.

Lt. Wayne Hanson of the Humboldt County Sheriff’s Office told NBC that no major damage or injuries were reported but that the shaking was significant.  The USGS “Did You Feel It” website had multiple reports from coastal areas of Level VI shaking, designed as “strong”.

Ironically, the quake struck as a “room full of Public Safety Officials” were meeting at the California Office of Emergency Services.

The USGS reported measurements from the quake over 200 miles to the north, east and south.
