    The Charleston Earthquake of August 31, 1886 was a powerful intraplate earthquake that hit the area of Charleston, South Carolina.

    The earthquake caused severe damage in Charleston, South Carolina, damaging 2,000 buildings and causing $6 million worth in damages (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.
    After the 1811 and 1812 quakes in New Madrid, Missouri, the Charleston SC earthquake is the most powerful and damaging quake to hit the southeastern United States.
    Three Main Shocks of the Missouri Earthquake
    December 16, 1811 - Magnitude ~7.7
    January 23, 1812 - Magnitude ~ 7.5
    February 7, 1812 - Magnitude ~ 7.7
    Also in 1755, a quake with around a 6.0 magnitude struck off the coast of Massachusetts.
    Why was Washington, DC affected more by this quake than Richmond, VA ??
    The sediments of the coastal plain along the eastern seaboard ( Washington DC ) can trap waves or concentrate the energy as they propagate and produce an amplification of the shaking or energy.
    If your area has a solid rock structure beneath ( Richmond ) it tends to spread out or disapate the energy at the surface. You see the top of this rock structure when looking at the James River falls when the river is low.
