According to the USGS, three smaller aftershocks hit the same area in the hours after the first quake: magnitude 2.1, magnitude 1.9, and magnitude 1.5.

Later, a magnitude 3.6 quake shook the area just after 7:00 p.m. The USGS said that earthquake occurred at a depth of 3 kilometers.

Two additional small aftershocks happened around 7:20 p.m.
