Damage from Charleston earthquake of August 31, 1886




One of many "earthquake bolts" found throughout period houses in the city of Charleston. These could be added to existing unreinforced masonry buildings to add additional support to the structure without having to demolish the structure due to instability. The bolts pass through the existing masonry walls tying walls on opposite sides of the structure together for stability.
The Charleston Earthquake of 1886 was a powerful intraplate earthquake that hit the area of Charleston, South Carolina. After the 1811 and 1812 quakes in New Madrid, Missouri, it is one of the most powerful and damaging quakes to hit the southeastern United States.[2][3] The shaking occurred at 9:50 p.m. on August 31, 1886 and lasted just under a minute. The earthquake caused severe damage in Charleston, damaging 2,000 buildings and causing $6 million worth in damage (over $141 million in 2009 dollars), while in the whole city the buildings were only valued at approximately $24 million. Between 60 and 110 lives were lost. Some of the damage is still seen today.
