M2.1 Quake in South Carolina
The image above shows the location of the magnitude 2.1 earthquake that struck South Carolina at 6.2km in depth at 7:47UTC on September 22, 2018. This area is not known to be seismically active, but they still do occur. I believe right when Hurricane Florence was hitting this area, an earthquake of similar depth and size occurred. This earthquake was very weird and had a hard time showing up on local seismographs. The closest seismic station I could find data for was SUMMV CO which appears to be about 25 miles away or so. Below is the seismogram/spectrogram analysis of this event along with the helicorders of the two closest seismic stations. You can tell it barely showed. Nevertheless, it is a very interesting event!
