How many earthquakes occur in the Blue Ridge Mountains?
Seismic Magnitude Scale
A seismic magnitude scale is used to determine the overall strength/force of an earthquake. Seismic waves, read by a seismogram, are used to tell what the magnitude of an earthquake is. There are different types of magnitude scales used because there are different types of earthquakes.

The Blue Ridge Mountains do sit on a fault line, but it has been inactive for over 300 million years. However, geologists expect this fault line to become active again in the future. As erosion occurs and the mountains change, there is some movement that occurs, but most of the time it can't be felt by humans. They usually have a magnitude of 2.5 or less. In the last 150 years, there have been 2 earthquakes of a 5.0 magnitude or greater that caused some minimal damage in nearby cities. It is possible for a nearby earthquake along a faultline to cause some shaking if a seismic event were to occur.
