Magnitude 2.3 Earthquake- WEST VIRGINIA

Periodically I look at the USGS Earthquake website. Being from the east coast where earthquakes are rare, it holds a certain fascination. I know from my school days that the Appalachians were formed my two continental plates colliding eons ago, and violent earthquakes forced them up.

The Appalachians still rumble to life once and awhile and Union, WV was hit with a 2.3 Quake.
