U.S. earthquakeIn 1886, the first U.S. earthquake on record with significant human consequence - the loss of some 100 lives - hit Charleston, S.C. and its massive effect spread through many eastern States. The epicenter was 15 miles northwest of Charleston, where 41 people died, 90 percent of the city's 6,956 brick buildings were damaged, and nearly all of its 14,000 chimneys were broken off at the roof. However, geologically the most severe earthquakes in U.S. history had occurred earlier in the century (16 Dec 1811). The epicenter then was in a sparsely populated region and caused no known casualties, so the human consequences were relatively not significant, although the violent movement of the ground changed the course of the Mississippi River and created many new lakes.« |
