"The plane can literally pick up these subtle differences (in the rock) and map them out," said College of Charleston geologist Scott Harris. These and other maps are being produced to increase the public awareness of quake-prone areas. It killed 100 people, leveled nine of every 10 brick buildings in Charleston and damaged nine of every 10 in Summerville. The damage was assessed to be between $5 million and $6 million. The intensities shown on the map below are the highest likely under the most adverse geologic conditions. This was the first seismic activity in South Carolina since two earthquakes a 2.4 magnitude quake east of . Some of these started directly after the earthquake and were more frequent and the longer after the earthquake, the more spaced out the aftershocks were. Phone Numbers |
The Geological Survey findings could guide writing codes more suited to specific locations, Harris said. The exact mechanisms of intraplate earthquakes are a subject of much ongoing research. The possibility of Charleston seeing California-level damage from shaking in 100 years sits between 36 and 74 percent, just one bracket below the Golden States chances.

Cornices from towers and high buildings fall. This almighty quake caused extensive damage to the transportation systems in central Alaska. [5] There were at least 60 fatalities. On the other hand, the powerful 5.8 magnitude Virginia quake in 2011 erupted from an unknown buried fault that Shah's survey later found. Similar faults are found all along the east coast of North America. With the development of earthquake studies and technology, this event has been extensively studied as an example of an intraplate earthquake. Archived Survey News
Lakes are dammed, waterfalls formed, and rivers are deflected. Officials say 1 in 10 people in the U.S. now live in high-hazard areas where strong shaking is likely during their lifetimes, according to the USGS, and during the past six years, strongly felt earthquakes have occurred in 21 states, including South Carolina. On this Wikipedia the language links are at the top of the page across from the article title. Perhaps the intraplate quakes felt in South Carolina are the result of stresses transmitted inward from the boundaries of the North American plate. Dams broke, which caused a lot of flooding in surrounding farms and roads. This map shows earthquake intensities, by county, based on the Modified Mercalli Intensity Scale. We know that there is a lot we can explain about these seismic events and wanted to help answer a lot of those questions and limit confusion among the media and members of the public.. According to the Department of Natural Resources, The majority of earthquakes worldwide occur at plate boundaries when plates stick and then jump past each other. The location of the river, its changing water levels and seasonal rainfall could be contributing factors. Well-built wooden structures are severely damaged and some destroyed. Rocks respond to stress (squeezed or pulled apart) near the Earth's surface by breaking, and when rocks move along either side of a fracture, it is called a fault. The Geologic Hazards of the South Carolina Coastal Plain map has been designed as a planning tool for use by emergency managers for the response to, and recovery from, a hazardous geologic event. It was reported to have been a 4.1 earthquake, which is rare for South Carolina. The 7.6 magnitude tremor was felt over 2.5 million square miles and caused damage as far away as 200 miles.

[7], Other man-made structures were also damaged as a result of earth splits caused by the earthquake. Another factor that affected the percent of buildings destroyed was what kind of ground these buildings were built on. 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. 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. Well-built wooden structures destroyed. Much of that state's coastal area is at risk.
