A magnitude 4.9 aftershock was reported Sunday evening at 11:32 p.m. off the Northern California coast, four miles from the epicenter of a magnitude 5.9 earthquake hours earlier, according to the U.S. Geological Survey.

The 4.9 quake occurred 64 miles from Fortuna, Calif., 65 miles from Eureka, 69 miles from Myrtletown, 72 miles from Arcata and 74 miles from McKinleyville.

After the magnitude 5.9 earthquake, which was reported at 7:59 p.m., no tsunami warning was issued for coastal areas, and no damage was reported.

Thousands of people on the USGS website reported feeling weak to moderate shaking from that quake from the Oregon border to the San Francisco Bay Area, some as far inland as the northern Sierra foothills surrounding Chico.

That earthquake was the only other quake of magnitude 3.0 or greater centered nearby in the last 10 days.

An average of five earthquakes with magnitudes between 5.0 and 6.0 occur per year in California and Nevada, according to a recent three-year data sample.

The aftershock occurred at a depth of 1.4 miles. Did you feel this earthquake? Consider reporting what you felt to the USGS.
