A small earthquake rattled Berks County, Pennsylvania, Friday afternoon.
The magnitude-2.2 temblor hit at 12:11 p.m. about 1.4 miles north-northwest of Spring Ridge, which is about 6 miles west of Reading, at a depth of 1.2 miles, the USGS reported.
Dozens of people reported feeling the quake, the USGS said.
The Pennsylvania Geological Survey said that it was a relatively shallow quake and could have been audible. Some people reported hearing a loud bang.
Earthquakes aren’t common, but do happen in the northeastern United States.
The most memorable earthquake felt in the Philadelphia region over the past decade was the magnitude 5.8 quake that rattled Virginia in 2011. That one was felt throughout the Philadelphia region and beyond.
From 2010 to 2015, however, no quakes over a magnitude of 3 were reported in Pennsylvania, New Jersey and Delaware, the USGS said.
