An earthquake is the violent shaking of the Earth caused by a sudden movement of rock beneath its surface. Around 70% of earthquakes in South Carolina occur in the Coastal Plain. Overview. The Palmetto state has a seismic past and will, no doubt, tremble again as quakes shake the ground beneath our feet.
One of the primary reasons South Carolina is vulnerable to damage from earthquakes is through a process called liquefaction - a process in which a saturated sand softens and loses strength due ...
Seismicity map of the State of South Carolina. The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States (Algermissen, 1969) which have been recompiled and updated through 1977.
Geologic Hazards in South Carolina include Liquefaction Areas, Collapse Potential, Landslide Potential, Faults, and Recent Seismicity. Please refer to the Geologic Hazards Map for descriptions and information on these hazards.
The various colors and line types indicate different ages of the most recent earthquakes on the fault and how well the location of the fault is constrained. For more details, see Quaternary Faults.Map showing Quaternary faults in the western U.S. and Pacific Ocean.
South Carolina has earthquakes and the hazards that go with them, such as seismic shaking and ground failure. The 1886 Charleston earthquake caused extensive damage in the city and throughout the Southeast, and was felt as far away as Ontario, Bermuda, and Cuba.
South Carolina's Fault System. Most of South Carolina’s earthquakes occur in the Coastal Plain where the underlying rocks are very faulted or broken from the break-up of the plates. These cracks in the deep rocks mean that this area of the plate is weak.
Eastern Piedmont Fault System (EPFS) consists of the green lines inside the black box. Some of South Carolina’s leading geologists have authored a report exploring the factors behind recent earthquakes in the Elgin area, an effort to help the public understand what is happening and why.
Check for sewage and water lines damage. If you suspect sewage lines are damaged, avoid using the toilets and call a plumber. If water pipes are damaged, contact the water company and avoid using water from the tap. You can obtain safe water by melting ice cubes.
South Carolina’s Fault System: Most of South Carolina’s earthquakes occur in the Coastal Plain where the underlying rocks are very faulted or broken from the break-up of the plates. These cracks in the deep rocks mean that this area of the plate is weak. If pressure is exerted on the edge of the plate, some of these faults/breaks will
