N2RkODJlNDk5Y2I5YzIxYzM5NTQ1OTFkYjVhZTMxMDRmNmI4YmY3NDYxY2U0 The fact that South Carolina has already seen a large quake in the past means that another large event is likely although when and where is virtually impossible to predict. The study says theres a higher risk for damage because more people live and work in these areas, and better methods have allowed experts to refine their earthquake hazard predictions. It also may be useful to land-use planners and regulators as a generalized guide to regional hazard mitigation actions. The map can be used to determine the types of rocks and sediments that can be found in specific areas of South Carolina. This event is significant because it demonstrates that large, destructive earthquakes can strike the Piedmont region.

The Earth's heat drives convection currents in the asthenosphere, moving the plates past one another very slowly. One of the primary reasons South Carolina is vulnerable to damage from earthquakes is through a process called liquefaction - a process in which a saturated sand softens and loses strength due during strong earthquake ground shaking. The 1886 Charleston earthquake occurred in the Charleston, S.C., seismic zone. According to the US Geological Surveys earthquake prediction model, Charleston is ground zero for a potential disaster with damage comparable to whats caused by shaking in California.
