Instead, we sit along the East Tennessee Seismic Zone. 88, Issue 1, pp. Lett., 43, doi:10.1002/2016GL070175. Groundwater age distributions developed from carbon-14 (14C), tritium (3H), and helium-4 (4He) concentrations, along with aquifer hydrologic position, water type, and redox conditions, were compared to geogenic contaminants of concern (GCOC) from 252 public-supply wells in six Atlantic and Gulf Coastal Plain unconsolidated-sediment aquifers.... Three sequences of well-documented, major ~M7+ earthquakes (1811-1812 CE, ~1450 CE, and ~900 CE) in the New Madrid seismic zone, USA, contribute significantly to seismic hazard in the region. The Eastern Tennessee Seismic Zone (ETSZ), also known as the East Tennessee Seismic Zone and the Southern Appalachian Seismic Zone, is a geographic band stretching from northeastern Alabama to southwestern Virginia that is subject to frequent small earthquakes.The ETSZ is one of the most active earthquake zones in the eastern United States. ... Eastern Tennessee; AG Network; Felt Reports; Shakemaps; The Southern Appalachian Seismic Network (SARSN) achieved a locational 206-223. The Southern Appalachian Seismic Zone, a seismic region stretching from northwestern Georgia, through Tennessee and into northeastern Alabama, was hit by a swarm of 5 earthquakes on February 11, 2020. Most of the earthquakes we experience in Alabama are associated with the Southern Appalachian Seismic Zone (an extension of the East Tennessee Seismic Zone) that runs along the Appalachian Mountains from the northeastern corner into the central part of the state and the Bahamas Fracture Seismic Zone in southern Alabama. 2020-06-21 11:12:42 UTC 1.9 magnitude, 19 km depth Loudon, Tennessee, United States 1.9 magnitude earthquake 2020-06-21 11:12:42 UTC at 11:12 June 21, 2020 UTC The following is an overview of the assessments: The Critical Minerals in Archived Mine Samples Database (CMDB) contains chemistry and geologic information for historic ore and ore-related rock samples from mineral deposits in the United States. The long cluster of circles stretching from Tennessee through the edge of western North Carolina into northern Georgia is known as the Eastern Tennessee seismic zone, or earthquake zone. Scientists are studying this area to determine why so many earthquakes happen here. Instead, we sit along the East Tennessee Seismic Zone. Map of active US fault lines in the USA by USGS. In addition, the database contains samples from archetypal deposits from 27 other countries in North America, South America, Asia, Africa and Europe. Due to proximity to the New Madrid fault line, most structures in Memphis are retrofitted to withstand earthquakes, but homes and buildings in Middle Tennessee generally do not have such prerequisites and likely will not need them. Click to enlarge. Use the links below to find out more about these zones … Knowledge of the local state of stress is critical in appraising intraplate seismic hazard. Seismic Zone (SASZ). Fish and Wildife Director Same Hamilton, and refuge manage John Taylor. The Southern Appalachian Seismic Network (SARSN) achieved a locational Global, national and regional networks recording earthquakes and crustal movements, maps, station information, real-time seismic waveforms. In addition to earthquake fault zones, information shown on Official Maps of Seismic Hazard Zones and other state and federal maps of natural hazards also must be disclosed. The Flynn Creek Crater Sample Collection consists of over two thousand boxes of drill core from 18 drill holes in the crater’s central uplift, floor, and rim.
