For hundreds of millions of years, the forces of continental drift have reshaped the Earth. Unlike more traditionally earthquake prone regions like the West Coast of the U.S, the reason behind earthquakes in South Carolina is a little more unlcear. South Carolina's quakes are located within a plate rather than at a plate boundary. Photo Galleries (See the Report on a 3.6 Magnitude Earthquake in the Lowcountry) The South Carolina Geological Survey (SCGS) is interested in making South Carolinians aware of our seismic past, what causes our earthquakes, what is being done to reduce the losses that will result from future quakes, and what you should do before, during, and after an earthquake. ZDQ3NmE2NjFjMzliYzFlYThlZTBhYWM1YzdiODk4NTFjODA4MGVhMDJiZTFl Twenty-seven years after the 1886 Charleston earthquake, another strong earthquake occurred in South Carolina.

[6], The Old White Meeting House near Summerville, Dorchester County, South Carolina was reduced to ruins. According to the US Geological Surveys earthquake prediction model, Charleston is ground zero for a potential disaster with damage comparable to whats caused by shaking in California. If outside, move to an area where you will be safe from falling trees, utility poles, or debris from buildings. This quake was on the afternoon of January 1, 1913, at 1:28 p.m. near the town of Union in Union County. Damage to poorly built or badly designed structures. This history of a strong quake, plus the continued presence of regular earthquake activity in the state, indicates this area is at an elevated hazard for a future powerful shock. It caused 60 deaths and $56 million ($165.88million in 2021) in damage to 2,000 buildings in the Southeastern United States.

A 7.8 magnitude earthquake rocked Turkey on Monday, leaving a devastating death toll of nearly 24,000. Wood frame structures are severely damaged, especially near epicenters. Few if any masonry structures remain standing. Earthquakes represented on the map occurred during August 31, 1886, Charleston, SC., earthquake and January 1, 1913, Union County, SC., earthquake. According to the US Geological Survey's earthquake prediction model, Charleston is ground zero for a potential disaster with damage comparable to what's caused by shaking in California. Earthquakes tend to cluster in other spots in the state, too, including along the Savannah River, where a minor quake near Aiken on Monday likely erupted from a buried fault. On Friday, February 14, 2014 at 10:23 p.m., an earthquake occurred in the midlands of SC. Sand boils were common throughout the affected area due to soil liquefaction. The Geologic Hazards of the South Carolina Coastal Plain map has been designed as a planning tool for use by emergency managers for the response to, and recovery from, a hazardous geologic event. The South Carolina Emergency Management Division encourages all residents to stay informed about and be prepared for earthquake activity in the state. This would be about 112 million dollars today.

Dams are seriously damaged. While investigation is ongoing, the events are not due to some mysterious, unexplained force. One of the problems we have here back on the eastern half of the country is we dont have earthquakes as often, which means we have far fewer recordings of how the ground moves in order to base our estimates of future earthquakes on," Jaume said. Perhaps the intraplate quakes felt in South Carolina are the result of stresses transmitted inward from the boundaries of the North American plate. "We can't predict earthquakes but we can prepare for them," Shah said. Many building owners added earthquake bolts to existing unreinforced masonry buildings in order to add support to the structure to avoid having to demolish it because of instability. The quake was the strongest earthquake to hit the East Coast. YzRmNzEwNDc0YTg2MmQzOGM2M2M2MmY3MGU4MmQ1ZWVhOGI3OWRkNzMyYzdm Users can explore the map's simplified geologic units of the state's geology that were created by generalizing more detailed, larger scale information.
