The area of significant damage was about 0.5 miles long and 900 feet wide, but it was felt over an area of about 40,000 square miles. at 19:12 January 20, 2020 UTC, Location:
During this time, the Earth’s crust in the region was buckled (folded) and shifted many miles to the northwest along thrust faults.
The USGS National Seismic Hazard Mapping Project develops these maps by incorporating information on known and potential earthquakes and the associated ground shaking obtained in science and engineering research and workshops, review by science organizations and state geological surveys, and advice from expert panels. Magnitude 5.5.
Rocks in fault zones are commonly thinly layered because their minerals were aligned and stretched by the tremendous pressures caused by fault movement. Valley Hill Taylor, J.C. Reid, R.M. Cherokee

In Western North Carolina, the shaking produced effects such as broken windows, damage to masonry (especially weak masonry), ringing bells, and furniture being moved or broken. The great earthquakes of 1811–1812 (magnitude 7.3–8.3) were centered in the Mississippi Valley near New Madrid, Missouri, and were felt throughout the state. The locations of earthquake epicenters in North Carolina do not consistently line up with known faults (as they do in California), indicating that the inactive faults exposed on the surface are not responsible for the earthquakes in this region.
The… Damage in North Carolina occurred mainly in the eastern and central parts of the state, but damage was reported in Waynesville.
(2.2 miles), 2020-01-20 19:12:11 UTC 3.2 km from Wilkes County Earthquake – August 31, 1861. Magnitude 5.1. These characteristics of fault zones influence the quantity, quality, and flow directions of groundwater, can affect the stability of rock slopes, and can make them ideal sources of flagstone.

Explore Brevard is the official tourism site of Transylvania County and Brevard NC also known as the Land of Waterfalls.
Many streams in the region have similar trends because their downward erosion exploited these weakened fracture zones in the bedrock.
The U.S. Geological Survey (USGS) produces National Seismic Hazard Maps that display potential earthquake ground motions for various probability levels across the United States. Carlson, J.H.
In contrast, there are no active fault zones in North Carolina. “Tectonic map of the southern and central Appalachians: A tale of three orogens and a complete Wilson cycle.” In R.D. 11.2 km from
Epicenter at 35.292, -82.513 The locations of earthquake epicenters in North Carolina do not consistently line up with known faults (as they do in California), indicating that the inactive faults exposed on the surface are not responsible for the earthquakes in this region. The major faults of Western North Carolina discovered thus far are ancient, and none are known to be active. http://nc-maps.stores.yahoo.net/gh2mapofeaep.html, http://gis.enr.state.nc.us/sid/bin/index.plx?client=zGeologic_Maps&site=9AM, http://earthquake.usgs.gov/hazards/products/conterminous/2008/maps/.
One example is the cluster of epicenters stretching from Tennessee through the edge of Western North Carolina and into northern Georgia and Alabama, called the Eastern Tennessee Seismic Zone.
at 02:11 May 05, 2020 UTC, Location: The quake was felt for over 200,000 square miles, including in the Carolinas, Alabama, Kentucky, and West Virginia. 2020-05-05 02:52:35 UTC These faults are not visible as breaks in the ground surface due to their antiquity, and similarly the known faults do not correspond with the locations of historic earthquake epicenters.
In Western North Carolina, several generations of igneous dikes are exposed at the surface today, but are too small to be displayed on the regional map. 5.2 km from Epicenter at 35.425, -83.332 Taylor, J.C. Reid, R.M. Merschat.
Rocks in fault zones are commonly thinly layered because their minerals were aligned and stretched by the tremendous pressures caused by fault movement. 2.2 km from Brevard Research is underway to more accurately understand the seismic potential in this region. The Brevard Fault Zone runs threw the southwest and northeast threw Georgia, Alabama, and North Carolina.
Scientists use various scales to determine the strength of an earthquake (fig.
East Flat Rock The major faults of Western North Carolina discovered thus far are ancient, and none are known to be active. Epicenter at 35.283, -82.519 Most of the earthquakes here are small, random, scattered movements of the Earth's crust. The most significant fault in the region is the Brevard fault zone, which extends from Alabama to Virginia across North Carolina, where it coincides with a long, linear topographic low.
