The New Madrid seismic zone (NMSZ), sometimes called the New Madrid fault line (or fault zone or fault system), is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.
South Carolina earthquakes occur with the greatest frequency along the central coastline of the state, in the Charleston area. South Carolina is the most seismically active state on the east coast. [1] At 7.3 magnitude, the Charleston earthquake of 1886 was the largest quake to ever hit the Eastern United States. This earthquake killed at least ...
New Madrid fault and earthquake-prone region considered at high risk today. The 1811–1812 New Madrid earthquakes were a series of intense intraplate earthquakes beginning with an initial earthquake of moment magnitude 7.2–8.2 on December 16, 1811, followed by a moment magnitude 7.4 aftershock on the same day. Two additional earthquakes of ...
In 1886, the effects of ground shaking from a large earthquake in Charleston, South Carolina could be felt as far away as New York City, New York, Chicago, Illinois and St. Louis, Missouri, USGS ...
The South Carolina State Fair is loaded with tasty foods every year, but this October the event has a few more unique treats to try.
The Palmetto State’s largest annual event, the state fair returns Oct. 9 through Oct. 20 at the South Carolina State Fairgrounds. This year will feature a host of new specialty foods and drinks ...
Photographic evidence of the South Carolina Railroad southeast of Summerville also showed a right-lateral offset of 4.5 ± 0.3 m (14.76 ± 0.98 ft) on the track. Direct observation of the earthquake's effects also reported the rail bed being "forced to the right", supporting the identification of this offset.
Examples of intraplate earthquakes include those in Mineral, Virginia, in 2011 (estimated magnitude 5.8), Newcastle, New South Wales in 1989, New Madrid in 1811 and 1812 (estimated magnitude as high as 8.6), [6] the Boston (Cape Ann) earthquake of 1755 (estimated magnitude 6.0 to 6.3), earthquakes felt in New York City in 1737 and 1884 (both ...
