On Dec. This earthquake occurred in the Central Virginia seismic zone. The Charleston earthquake occurred in the Charleston, S. It is very important to realize that even though North Carolina and the east coast of the United States experience occasional earthquakes, this area is not a seismically active area like California and the West Coast.
In California there are many active faults where large, damaging earthquakes occur frequently. In contrast, there are no active fault zones in North Carolina. Earthquakes are more frequent in the western part of our state, but statewide they are relatively small, random and scattered events. This scale has twelve levels designated by Roman numerals I — XII one through twelve , to symbolize the amount of damage felt by the earthquake.
Many factors determine the intensity of an earthquake at the surface of the earth, such as the depth where the earthquake originates and what kinds of rock and soil are at the surface. There have been a few strong earthquakes in our mountain region in the last years. In there was a large earthquake centered in Charleston, S. It was estimated to be a magnitude 6. An isoseismal map indicates areas of equal iso shaking seismicity.
This earthquake was felt up and down the East Coast and throughout the Midwest. It was the most damaging earthquake in the Southeast and one of the largest earthquakes in the eastern United States in historical times. Compare the area affected by the Charleston earthquake to the area covered by the North Carolina earthquake. Earthquakes happen every day around the world.
