Archived Survey News Railroad tracks were bent in all directions in some locations across the Low Country. Copyright 2019 WCSC. With the development of earthquake studies and technology, this event has been extensively studied as an example of an intraplate earthquake. This almighty quake caused extensive damage to the transportation systems in central Alaska. A fault line runs through Summerville, and seismologists say the Charleston area is at high risk for a damaging temblor within the next half-century. [15], The initial shock in Charleston lasted for about 45 seconds and was extremely destructive, leaving nearly all of the 8,000 city structures with either interior damage or broken windows. C.

Most foundation and frame structures destroyed. Large amounts of rock may move. The ground moves in waves or ripples. 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. Some bridges are destroyed. Small bells in churches, chapels, and schools ring. The violent tremors went on for a full minute and the quake measured a magnitude 7.6. The ground liquefied in many spots which further damaged many buildings, roads, bridges, and farm fields. Shaking was felt from the western portion of South Carolina into northern Georgia and North Carolina, and even up into parts of Virginia. Twenty-seven years after the 1886 Charleston earthquake, another strong earthquake occurred in South Carolina. YjM3YmMzMzdjNTc0MzQ3ZWIyZjA4OGE5MGMzZWE5ZTY5NTYzYTZlZTgwMWNm Flood Mitigation Program In 2001, the South Carolina Emergency Management Division conducted an in depth study on the risk and potential damage from earthquakes in the future. South Carolina earthquakes occur with the greatest frequency along the central coastline of the state, in the Charleston area. "We can't predict earthquakes but we can prepare for them," Shah said. College of Charleston geologists and students are participating in the survey. Helpful Links, South Carolina Geological Survey The strongest recorded earthquake along the East Coast happened in Charleston, South Carolina in 1886. The Rossi-Forel Scale initially used to describe the January 1, 1913, Union County, S.C., earthquake is considered comparable to the Modified Mercalli Intensity Scale for the purpose of developing this map. This map shows earthquake intensities, by county, based on the Modified Mercalli Intensity Scale. South Carolina's quakes are located within a plate rather than at a plate boundary. The 1886 Charleston earthquake occurred about 9:50p.m. local time August 31. The U.S., particularly along the west coast, is susceptible to large earthquakes. These quakes often are the ones that are the most destructive and well understood in terms of plate tectonics. Mineral Resources Where there's a split, the differences will show up in lines. Water is thrown on the banks of canals, rivers, and lakes. Numerous windows are broken. Links Unstable objects overturned. ELGIN, South Carolina The USGS is providing scenarios to estimate the chance of larger earthquakes as part of an ongoing swarm in the region. This quake struck with a magnitude of 5.5. Sadly, about 60 people did not survive the quake. [3] 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. 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. Earthquakes represented on the map occurred during August 31, 1886, Charleston, SC., earthquake and January 1, 1913, Union County, SC., earthquake. [6], The Old White Meeting House near Summerville, Dorchester County, South Carolina was reduced to ruins. Temporary or permanent changes may occur in springs and wells; sand and mud are ejected in small amounts.

The unusually long earthquake swarm in the Midlands area has understandably led to a lot of questions and speculation, said State Geologist Scott Howard, with the S.C. Geological Survey under SCDNR. Similar faults are found all along the east coast of North America. Pictures fall off walls. [5] Minor earthquake activity that still continues in the area in the early 21st century may be a continuation of aftershocks. These sorts of maps just remind people and policy makers, as well as planners, that just because it happened a long time ago doesnt mean our risk isnt still here, said Dr. Norman Levine, asst. For hundreds of millions of years, the forces of continental drift have reshaped the Earth. Dutton, C.E., 1889, The Charleston earthquake of August 31, 1886: U.S. Geological Survey Ninth Annual Report, 1887-88, p. 203-528. The study stated that in the event of a magnitude 6.3 earthquake in Charleston, approximately 136,000 buildings will sustain slight to moderate damage and 25,000 will be extensively damaged. Objects fall from shelves. Some sand and gravel stream banks cave in. The 1886 Charleston earthquake occurred in the Charleston, S.C., seismic zone. 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.

The Elgin earthquakes have not been intense enough to cause damage. 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 rash of quakes started in December of 2021, when 16 quakes were reported in Kershaw County, SC with most of the activity centered near Elgin and Camden. South Carolina is among 16 states in the U.S. with the highest risk for earthquakes, according to an update from the U.S. Geological Survey. 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.

M2Y4MjY5ZjYxMDVjYTRlMDgyYjZhZDMwYjQxYzcwMThlNTA5YmQ4YmZhYjEy Low around 65F. [3], Scientists have classified it as an intraplate earthquake, and said that it had an estimated moment magnitude of 6.97.3 and a maximum Mercalli intensity of X (Extreme). The majority of earthquakes worldwide occur at plate boundaries when plates stick and then jump past each other. Flood Mitigation Program The last earthquake with a magnitude higher than 3.0 reported in the state was on Sept. 9, with a 3.3-magnitude earthquake near Charleston, according to the USGS. It was reported there to be 300 smaller aftershocks within the first 30 years following the earthquake in 1886 and 435 total.[10]. In South Carolina, geologists have recently discovered evidence of at least five large paleoearthquakes during the past 5,000 years (Amick and Gelinas, 1991).
