Columbia, SC 29212 In South Carolina, approximately 70 percent of the earthquakes occur in the Coastal Plain and most are clustered around three areas west and north of Charleston: Ravenel-Adams Run-Hollywood, Middleton Place-Summerville, and Bowman. An earthquake is the violent shaking of the Earth caused by a sudden movement of rock beneath its surface. Studying these faults is difficult since many of the most previously active faults are buried deep in sediment across the coastal plain. According to the Department of Natural Resources, The majority of earthquakes worldwide occur at plate boundaries when plates stick and then jump past each other.

According to a study commissioned by SCEMD, an earthquake of similar magnitude occurring today would result in tremendous loss of life, severe property damage and extreme economic loss. This area has the highest concentration of ancient fault lines in the state. Officials say 1 in 10 people in the U.S. now live in high-hazard areas where strong shaking is likely during their lifetimes, according to the USGS, and during the past six years, strongly felt earthquakes have occurred in 21 states, including South Carolina. The coastal area around Charleston is particularly vulnerable to quakes. Project chief Mark Petersen said parts of Washington, Oregon, Utah, Oklahoma, Colorado, Wyoming and Tennessee moved into the top two hazard zones.Parts of 16 states have the highest risk of earthquakes: Alaska, Hawaii, California, Oregon, Washington, Nevada, Utah, Idaho, Montana, Wyoming, Missouri, Arkansas, Tennessee, Illinois, Kentucky and South Carolina.The South Carolina Emergency Management Division says the state generally experiences 15 to 20 earthquakes a year, though many are weak enough to be imperceptible.In February, there was a 4.1 magnitude earthquake that was felt across the Upstate. An Earthquake Today: We have a stock of older buildings that were not built for earthquakes, whereas out west, they have a lot less of that, simply because they happen more often. OTAyNzk0YjEzNDJjNTkzODdhNDNiMGE1ZjUxMjIwODU3NzlhODkwMWJkMzk5 The land around a fault may shift horizontally, vertically, or a combination of these motions (see Figure 5).

Helpful Links, South Carolina Geological Survey It is one of the most powerful and damaging earthquakes to hit the East Coast of the United States. . 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 theWestern U.S., faults often break the surface in lines and are easily mapped. A few minor quakes are felt in the Lowcountry each year. That shaking reportedly damaged structures as far away as 200 miles from downtown Charleston and was felt from Cuba to New York and as far west as the Mississippi River, according to the South Carolina Department of Natural Resources. SCGS is now conducting studies to evaluate the geologic response to earthquake-induced motion in an attempt to help reduce the risk to lives and property. People have difficulty standing.

The ground liquefied in many spots which further damaged many buildings, roads, bridges, and farm fields. The first aftershock followed just ten minutes later, and had the city rumbling once again. In our state, quakes may occur along ancient plate boundaries where existing faults are reactivated as the tectonic stress is released. Widespread power failure, transportation disruption and water system issues would follow. It was felt over a 2.5 million square mile area, from Cuba to New York and Bermuda to the Mississippi River.Twenty-seven years after the 1886 Charleston earthquake, a 5.5 magnitude earthquake shook Union County on Jan. 1, 1913.
