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. ZWMwYmYzZmI3MmU5NTA0YzJlYWY2ODVjNWQxZjdjYmMyZTY4M2ExNzJkZGUw Pictures on the wall move. Twenty-seven years after the 1886 Charleston earthquake, another strong earthquake occurred in South Carolina. NTg2YTQxMGVlY2JmYzhlYmIxOTJiOWM5YjNjZDEzZTk5N2ExZTQxZjE1NGU3 In 2001, the South Carolina Emergency Management Division conducted an in depth study on the risk and potential damage from earthquakes in the future. Where the lines converge like a web is where earthquakes tend to occur in the eastern United States, said AnjiShah, a Geological Survey research geophysicist heading up the project. South Carolinas quakes are located within a plate rather than at a plate boundary.

YjZkNGFiZTkxNzdhOGQ3NjBiODJhNTFkZDE4YjVlOWMwYWQ0ZDljMTFmOTNi In the softer underground sediment here, the shakes are stronger, last longer, come more frequently and can cause more damage. The most infamous and damaging of all South Carolina earthquakes happened in Charleston on the night of Aug. 31, 1886. Everyone feels movement. According to the South Carolina Emergency Management Division, approximately 10 to 20 earthquakes are recorded each year in South Carolina with only 3 to 5 of them felt or noticed by people. They had no way of knowing that shock waves from a massive quake (see Figure 1), estimated magnitude of 7.6, would throw them out of bed. The geologists, from the S.C. Department of Natural Resources Geological Survey, the University of South Carolina and College of Charleston, sought to explain the concept of earthquake swarms, the numbers of earthquakes that have been experienced in the Elgin area during the past seven months, the difference between magnitude and intensity when measuring seismic events and why the earthquakes have been occurring so frequently along the Interstate 20 corridor between Elgin and Lugoff. Geologists call them "buried faults," and mapping the webs could give scientists a better idea of whereand over a long time span when a next destructive earthquake could occur here. Perhaps the intraplate quakes felt in South Carolina are the result of stresses transmitted inward from the boundaries of the North American plate. If in a public building, avoid stairways and elevators and don't run for exits. Note: McGee and others (1986) source for Figures 2 through 4 and Figure 9. Users can explore the map's simplified geologic units of the state's geology that were created by generalizing more detailed, larger scale information. On the other hand, the powerful 5.8 magnitude Virginia quake in 2011 erupted from an unknown buried fault that Shah's survey later found. These faults and other geologic structures related to the earthquakes are hidden by the thick sequence of sediments. Imagine how bewildered and frightened they must have been as they darted for safety when ceilings gave way and tons of debris rained down about them. Please refer to the Geologic Hazards Map for descriptions and information on these hazards. This was the first seismic activity in South Carolina since two earthquakes a 2.4 magnitude quake east of . Carbon Sequestration Get under a desk or table and avoid outside walls, especially glass walls.

Earthquakes in South Carolina The shock was felt as far away as Boston, Massachusetts, to the north, Chicago, Illinois, and Milwaukee, Wisconsin, to the northwest, New Orleans, Louisiana, to the west, and across water to Cuba to the south, and Bermuda to the east. Geologists are exploring the possible effect of the nearby Wateree River on the frequency of the earthquakes. It is estimated that 14,000 chimneys fell in Charleston from the shaking. In our state, quakes may occur along ancient plate boundaries where existing faults are reactivated as geological stress is released. Report: SCs Lowcountry, Charleston faces high risk of earthquake damage, Law enforcement pursuit ends on Westmoreland Bridge, BLOG: Day 27: Jury hears closing arguments from state in Murdaugh murder trial, VIDEO: Summerville family wants to be paid for damage from garbage truck fire, US Geological Surveys earthquake prediction model, publicfile@live5news.com - (843) 402-5555. [citation needed]. 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. Reservoirs suffer severe damage. Shaking was felt from the western portion of . Bridges destroyed. This map shows earthquake intensities, by county, based on the Modified Mercalli Intensity Scale. The earthquake happened at about 1.5 miles beneath the surface, according to the USGS. Heavy furniture is overturned and damaged. [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. 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. South Carolina earthquakes occur with the greatest frequency along the central coastline of the state, in the Charleston area. YWNmMjkyNGU3YmQwNGFhNzBmZGMwMDg0OTkwY2EwMmEzODg3ZWU1ZmUzODRi N2YwZjljOWIyZTEzZjU1ZTE1YTE0M2I1MzU5MThiMDMwMDA4MzZjNTg4M2Vh Nystrom, P.G., Jr., Assisted by Clendenin, C.W., Jr., and Doar, W.R., III, 1996, Earthquake hazard map of the South Carolina Coastal Plain: South Carolina Geological Survey, General Geologic Map Series, 1p. On Friday, February 14, 2014 at 10:23 p.m., an earthquake occurred in the midlands of SC. Earthquake Education Center, South Carolina Earthquakes, (no date), Charleston Southern University Booklet. 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 during strong earthquake ground shaking. 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 relationship was negligible as it pertains to the damages of buildings made of brick. Total loss to buildings will be about $230 million., The study also examined the potential impact of a smaller earthquake near Columbia. MTlhZTg4NGZlN2M4ZDc5ZTlmYjI2NjEwYWFlNWY2Zjk1YzQ5YzBiODhmYWZh Within the city, many of the buildings sustained damage; some had to be torn down and rebuilt. The Palmetto state has a seismic past and will, no doubt, tremble again as quakes shake the ground beneath our feet. MjI4NDlmM2U0MTQzYWM3Y2FmYjkwOTlmNTYwY2YwN2U4OTQwNDQ1MzQyYzIy There was minimal damage and no deaths, but shock waves were felt as far away as Georgia and parts of Virginia. ZjY1M2JkMDgyMGE3ZDYzMGEyNjFkODEyODMzNzg2NjkxNmZlMmYyYTcwNjc0 Junior science on file, 1991: Facts on File. Earthquake Notification Service An earthquake is the violent shaking of the Earth caused by a sudden movement of rock beneath its surface. The land around a fault may shift horizontally, vertically, or a combination of these motions (see Figure 5). The top 15 most seismically active and vulnerable states in the US are Alaska, Hawaii, California, Oregon, Washington, Nevada, Utah, Idaho, Montana, Wyoming, Missouri, Arkansas, Tennessee, Illinois, and Kentucky. It was felt as far west as Atlanta and as far north as Hickory, N.C., each about 150 miles away.The most infamous and damaging of all South Carolina earthquakes happened in Charleston on the night of Aug. 31, 1886. Another earthquake struck the Elgin and Camden areas this afternoon measuring a 2.9. OTAyNzk0YjEzNDJjNTkzODdhNDNiMGE1ZjUxMjIwODU3NzlhODkwMWJkMzk5 Shaking was felt from the western portion of South Carolina into northern Georgia and North Carolina, and even up into parts of Virginia. Drivers have trouble steering. Rails bent. YTY0ZjEwNDg4NzNhYjgyOWNhY2M0Yjk1ZGNmMWRkMGU2YmQ0NWU0ZDY1YThj Poorly built buildings are damaged slightly. Columbia, SC 29212 Though the frequency of these minor earthquakes may alarm some, we do not expect a significantly damaging earthquake in South Carolina at this time, even though we know our state had them decades ago, SCEMD Director Kim Stenson said. 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. (South Carolina Earthquake Education and Preparedness, College of Charleston.) Buildings constructed on made ground were significantly more likely to be damaged than buildings constructed on solid ground; however, this relationship only occurred in wood-frame buildings, with 14% of wood-frame buildings built on made ground sustaining damages, compared to 0.5% of wood-frame buildings built on solid ground sustaining damages. Much of that state's coastal area is at risk. Some of these started directly after the earthquake and were more frequent and the longer after the earthquake, the more spaced out the aftershocks were. SEGSA Presentations Most masonry and frame structures are destroyed, including their foundations. The quake was even felt in cities as far as Boston and Chicago, where plaster fell from ceilings in upper floors of some buildings. Sixty people died in the quake and many of the city's brick and masonry buildings had crumbled. This can cause severe damage to structures as the ground beneath them becomes highly unstable. [8], Wires were cut and the railroad tracks were torn apart, cutting residents off from the outside world and vice versa. Earthquakes are not an uncommon occurrence in South Carolina. Plaster in walls might crack. The Earth's heat drives convection currents in the asthenosphere, moving the plates past one another very slowly. 5 Geology Road The intensities shown on this map are the highest likely under the most adverse geologic conditions that would be produced by a combination of the August 31, 1886, Charleston, S.C., earthquake and the January 1, 1913, Union County, S.C., earthquake. MDJmNmIwYjYzMWYxOThjNmIyNDJjNDM3NzM0MWE2ZDE4ZjIwNWEyYzNkNzcz Those structures that remained standing bore great cracks and other scars (see Figure 2). The South Carolina Emergency Management Division encourages all residents to stay informed about and be prepared for earthquake activity in the state. The intensity map below shows the highest likely earthquake intensity by county based on the most adverse geologic conditions. Perhaps the intraplate quakes felt in South Carolina are the result of stresses transmitted inward from the boundaries of the North American plate. Project chief Mark Petersen said parts of Washington, Oregon, Utah, Oklahoma, Colorado, Wyoming and Tennessee moved into the top two hazard zones. This map shows the major fault lines in the US! South Carolina is the most seismically active state on the east coast. NDU1NjQ3Y2M5NjJmZmY3YThjODQzNjMxYzFlY2NhZDVkZTdlNWNiYmRjYmZj Photo Galleries NzhmOWMyNWFmODI2MmY0ZTYyYWQzYjJlNzU5OTE4OTBmMzViZDQxYzgyNzQ0 7.0 and higher: Extreme damage. The majority of earthquakes worldwide occur at plate boundaries when plates stick and then jump past each other. Hydrology Section 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. Chimneys broken. Safely bring the car to a stop and turn on the radio for emergency broadcasts. The strongest earthquake on record to hit the eastern U.S. struck near Charleston on the night of August 31st, 1886. CHARLESTON, S.C. (WCSC) - A new report shows the Lowcountry is one of the only areas along the East Coast at high risk for damage from earthquakes. This is the 6th quake since Monday mornings 3.1. 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. Windows crack in some cases. The violent tremors went on for a full minute and the quake measured a magnitude 7.6. Most people indoors feel movement. ZDQxMmRkNjkyNTExMzJiMDEwZWMzY2Q1YmUyMDRjZDY2YjIwYjE5ZDJjZmUz The ground liquefied in many spots which further damaged many buildings, roads, bridges, and farm fields. Earthquake Notification Service The location of the river, its changing water levels and seasonal rainfall could be contributing factors. South Carolinians need to realize that South Carolina faces the possibility of the occurrence of a strong quake having its epicenter within our borders. [5] Minor earthquake activity that still continues in the area in the early 21st century may be a continuation of aftershocks. Similar faults are found all along the east coast of North America. Total building loss including capital stock and income losses will exceed $2 billion., When modeling a magnitude 5.3 Charleston earthquake scenario, the report went on to state that the losses and casualties decrease significantly. 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. This area has the highest concentration of ancient fault lines in the state. Hydrology Section 71 earthquakes in the past 365 days.
