Nearly 75% of the country is at risk for a potentially damaging earthquake in the next 100 years, according to a recently updated map from the U.S. Geological Survey. The map is the first to ...
The map and accompanying study offer precise information about the regions most at risk of earthquakes, and which types of quakes are likely to occur. The scientists also learned more about places ...
The state typically experiences between 10 and 20 earthquakes above magnitude 2.0 each year, said Andy Newman, a professor of geophysics at Georgia Tech. As for what’s behind the recent shakes ...
The first Georgia-specific geologic map was created in 1825. The most recent state-produced geologic map of Georgia, by the Georgia Department of Natural Resources is 1:500,000 scale, and was created in 1976 by the department's Georgia Geological Survey. [1] It was generated from a base map produced by the United States Geological Survey.
The USGS issued a fact sheet in 2009 stating the estimate of a 7–10% chance of a New Madrid earthquake of magnitude comparable to one of the 1811–12 quakes within the next 50 years, and a 25–40% chance of a magnitude 6 earthquake in the same time frame. [32] In July 2014, the USGS increased the risk assessment for the New Madrid area. [33]
The Appalachian foreland of Georgia, which lies in the northwest corner of the state, is separated from metamorphic rocks of the western Blue Ridge by the Talladega-Cartersville-Great Smoky fault. The oldest rocks of the foreland include Cambrian-Ordovician stratigraphy of the Chilhowee Group , Shady Dolomite , Rome Formation , Conasauga Group ...
