One of the problems we have here back on the eastern half of the country is we dont have earthquakes as often, which means we have far fewer recordings of how the ground moves in order to base our estimates of future earthquakes on," Jaume said. The violent tremors went on for a full minute and the quake measured a magnitude 7.6. The quake was even felt in cities as far as Boston and Chicago, where plaster fell from ceilings in upper floors of some buildings. The damage was assessed to be between $5 million and $6 million. South Carolina is among 16 states in the U.S. with the highest risk for earthquakes, according to an update from the U.S. Geological Survey. Earthquake swarms groups of earthquakes that occur close together in time and location and are similar in size -- are common and have occurred in South Carolina before. The centers more localized report is set to be released in March. The strongest recorded earthquake along the East Coast happened in Charleston, South Carolina in 1886. Everyone feels movement.

It is very important to realize that even though North Carolina and the east coast of the United States experience occasional earthquakes, this area is not a seismically active area like California and the West Coast. Check for and extinguish fires, and check for and correct conditions such as spilled gasoline that could lead to a fire. Geologists call them "buried faults," and mapping the webs could give scientists a better idea of whereand over a long time span when a next destructive earthquake could occur here. Given the necessary conditions, a magnitude 5.5 quake can generate liquefaction features that could cause damage to existing facilities and property. Please refer to the Geologic Hazards Map for descriptions and information on these hazards. The map can be used to determine the types of rocks and sediments that can be found in specific areas of South The first aftershock followed just ten minutes later, and had the city rumbling once again.
