A 4.4-magnitude earthquake shook near the California-Nevada border by Walker on Monday, Aug., 8 the U.S. Geological Survey reported.
The 3-mile deep quake hit 5 miles northeast of Walker at 1:44 p.m. Pacific time, according to the USGS.
More than 200 people from as far away as San Francisco and Auberry had reported feeling the tremor to the agency as of 3 p.m. Aug. 8.

Quakes between 2.5 and 5.4 magnitude are often felt but rarely cause much damage, according to Michigan Tech. Quakes below 2.5 magnitude are seldom felt by most people.
