For more information, contact the South Carolina Department of Natural Resources Communications Office by emailing Newsdesk@dnr.sc.gov. Some of South Carolinas 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. 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. OWEzNzFjZjFjMjk1OTljOWU5NTc0YmQ0NjM2ZTkwYTg2YjVkYzZjZWVhYTZh document.getElementById("demo").innerHTML = "© " + html; Meteorites 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. The 1886 Charleston earthquake occurred about 9:50p.m. local time August 31. It caused multiple fires and water lines and wells were ruptured and broken. But the seismic standards in building codes are based on Western quakes. Project chief Mark Petersen said parts of Washington, Oregon, Utah, Oklahoma, Colorado, Wyoming and Tennessee moved into the top two hazard zones. [citation needed]. SEGSA Presentations Within the city, many of the buildings sustained damage; some had to be torn down and rebuilt. File, A plane flown by a contractor for the U.S. Geological Survey is mapping earthquake faults underground. 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.

Low around 65F. eyJtZXNzYWdlIjoiM2JkMTVmMmEwMjYxNjk0MWM1ZmYxZmUyYWY4NGE2ZTg0 The study says theres a higher risk for damage because more people live and work in these areas, and better methods have allowed experts to refine their earthquake hazard predictions. Weary, D.J., 2008, Preliminary map of potentially karstic carbonate rocks in central and southern Appalachians states: U.S. Geological Survey Open-File Report 2008-1154, Available online only at https://pubs.usgs.gov/of/2008/1154/, last accessed 15 April 2011.

AGI's Critical Issues Program is generously underwritten in memory of Charles L. Weiner. Archived Survey News American Geosciences Institute. Once data about an area have been gathered, maps that show levels of risk for an area can be produced. If possible, get under a sturdy table, desk, or bed, or stand in a doorway. Damage is total, and nearly all works of construction are damaged greatly or destroyed. MDkzNzYxZTdmNTY2N2FlOTNmZjBmNmY4ZjQxNjZlNjFkYjQ5NTNhZWVmMjFi This event is significant because it demonstrates that large, destructive earthquakes can strike the Piedmont region. What we don't have a good handle on is what the risk is. 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. Check for injuries to others and provide assistance as needed. This quake was the strongest earthquake known to hit the Eastern Seaboard, and it shook with such force that it was felt over 2 1/2 million square miles (from Cuba to New York, and Bermuda to the Mississippi River).

[12], Local photographer George LaGrange Cook took a series of photographs of the city after the quake, publishing them as Cook's Earthquake Views of Charleston and Vicinity. They will take to the field afterward to make point-specific measurements to further the research, Harris said. Those that remained standing had cracks and other scars from the violent shaking. This area has the highest concentration of ancient fault lines in the state. "We know there is a risk of earthquakes (in the Charleston area). This map shows earthquake intensities, by county, based on the Modified Mercalli Intensity Scale. [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). This would be about 112 million dollars today. 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. [6], The Old White Meeting House near Summerville, Dorchester County, South Carolina was reduced to ruins. Lakes are dammed, waterfalls formed, and rivers are deflected. This quake struck with a magnitude of 5.5. Perhaps the intraplate quakes felt in South Carolina are the result of stresses transmitted inward from the boundaries of the North American plate.
