The tremor registered just west of Sinking Spring at 3:47 a.m. Friday, according to the National Earthquake Information Center of the U.S. Geological Survey. The quake was 1.8 miles deep, and more than 150 reported they felt the quake.
The Morning Call reported that the same area felt a 1.7-magnitude quake was recorded at 1:40 p.m. on Sunday.
A 1.6 magnitude earthquake was recorded near Leesport around 2 a.m. Friday as well.

The most significant earthquake to shake the state was in 1998 when a 5.2-magnitude tremor shook the northwestern part of the state.
There was minor structural damage reported and it had significant impacts on the local groundwater system.
