A moderate earthquake shook up the North Coast Wednesday afternoon. At 1:09PM the U.S. Geological Survey measured a magnitude 5.7 quake 40 miles southwest of Eureka. It was centered 11 miles beneath the ocean floor. People reported feeling it as far away as Red Bluff. There have been dozens of smaller quakes detected at the same place over the past day, including magnitude 3 quakes that followed the big one at 1:15PM and 2:34PM. Meanwhile to the east, a swarm of small quakes, and a few bigger ones, have continued at a location in the northwestern corner of Nevada. A magnitude 4.2 struck at 3:03AM Thursday morning.
