The quake was the strongest earthquake to hit the East Coast. Numerous windows are broken. 5 Geology Road Most foundation and frame structures destroyed. Studying these faults is difficult since many of the most previously active faults are buried deep in sediment across the coastal plain. Around 70% of earthquakes in South Carolina occur in the Coastal Plain. Yzk2OWQ1YmQ2MzA5YjFmZjIwNmRmYjM1MjIxNTUzNjMwOTIxODBmOGM4MDhh American Geosciences Institute. These quakes often are the ones that are the most destructive and well understood in terms of plate tectonics. We also need to realize that a major earthquake anywhere in the Eastern United States could adversely affect us, causing damage. [6], The most prominent buildings that were destroyed were commercial buildings, while residential buildings sustained significantly less damage. It caused 60 deaths and $5-6 million ($165.88 million in 2021) in damage to 2,000 buildings in the Southeastern United States. It was reported to have been a 4.1 earthquake, which is rare for South Carolina. The strongest earthquake on record to hit the eastern U.S. struck near Charleston on the night of August 31st, 1886.

File, A plane flown by a contractor for the U.S. Geological Survey is mapping earthquake faults underground. Similar faults are found all along the east coast of North America. This quake was on the afternoon of January 1, 1913, at 1:28 p.m. near the town of Union in Union County with an estimated magnitude of 5.5 (Figure 1). 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. and Bollinger, G.A., 1990, Forecasting damaging earthquakes in the Central and Eastern United States: Science, v. 249, p. 1412-1416. As shown in Figures 3 and 4, paleoliquefaction features, considered earthquake induced, have been found in South Carolina's coastal area. If outside, move to an area where you will be safe from falling trees, utility poles, or debris from buildings. It was reported there to be 300 smaller aftershocks within the first 30 years following the earthquake in 1886 and 435 total.[10]. All rights reserved. Check for injuries to others and provide assistance as needed. It caused 60 deaths and $56 million ($165.88million in 2021) in damage to 2,000 buildings in the Southeastern United States. That city in 2008 had a population in excess of 348,000. The South Carolina Geological Survey's interactive map provides an overview of the geology of South Carolina. (South Carolina Earthquake Education and Preparedness, College of Charleston.) 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. [8], Wires were cut and the railroad tracks were torn apart, cutting residents off from the outside world and vice versa. 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. Most masonry and frame structures are destroyed, including their foundations. 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. These quakes often are the ones that are the most destructive and well understood in terms of plate tectonics. The coverage map also reflects the current availability of this information across the state. The ground moves in waves or ripples. Large amounts of rock may move. 38, No. South Carolinians need to realize that South Carolina faces the possibility of the occurrence of a strong quake having its epicenter within our borders.
