It was a 7.3 magnitude temblor considered the worst recorded in the eastern United States. The College of Charleston professors who operate the center are taking a more localized look at how the Holy Citys buildings and other infrastructure would respond. In theWestern U.S., faults often break the surface in lines and are easily mapped. This quake was the strongest earthquake known to hit the Eastern Seaboard, and it shook with such force that it was felt over 2 1/2 million square miles (from Cuba to New York, and Bermuda to the Mississippi River). Flood Mitigation Program The deep rock beds under the Charleston area are split apart, creating webs of cracks underground. Carbon Sequestration The Geological Survey findings could guide writing codes more suited to specific locations, Harris said. Many building owners added earthquake bolts to existing unreinforced masonry buildings in order to add support to the structure to avoid having to demolish it because of instability.
