Charleston Earthquake

The Charleston Earthquake

One of the most disastrous earthquakes ever experienced east of the Mississippi River occurred late on August 31, 1886. The epicenter was 15 miles northwest of Charleston, South Carolina, where at least three-fourths of the buildings were wrecked or badly damaged. Roughly 100 people were killed in the entire affected area, including over 40 in Charleston itself. The shock was felt as far away as Bermuda, Cuba, and Toronto, Canada.

In the Charleston area, the quake opened deep cracks in the ground, which emitted clouds of sulfurous gas. Falling buildings were the principal cause of death. Many of the victims were people who, after the first tremors, rushed out into the city streets expecting to see the end of the world. They were then exposed to a rain of debris as subsequent shocks brought down walls and roofs.

On December 2, 1977, residents of the Charleston area heard booming sounds, which were believed to be similar to the sounds that had preceded the 1886 quake. The two explosion-like sounds were strong enough that they rattled windows. On December 15 two mild quakes in Charleston were preceded by five more booms. On December 20 there were yet two more booms. Records of similar mysterious booms go back for centuries, but the exact cause is as of yet unknown.
