The estimated magnitude of this earthquake ranged from 7.0 to 7.9 with a surface wave magnitude of close to 8.5. Tuomey was succeeded by Eugene Allen Smith, who built on the initial researches to establish the geological history of the state. The earthquake that occurred Wednesday didn't happen near a fault line in Tennessee, for the most part, the state is free of any faults that would suggest a vulnerability to earthquakes. The Kansas Earthquakes page on the KGS website includes a continuously updated interactive map that shows where earthquakes have occurred in the state since 2015. Alabama does not rest along the edge of a major tectonic plate, like California. Tap/click on "gear icon" for options and settings. [7] [8] The largest earthquake in recorded Alabama history measured an estimated magnitude of 5.1 and occurred October 18, 1916 near Irondale, and resulted in widespread panic, damage to structures, and dramatic changes in water well levels. The USGS has a faults website that includes an interactive fault map that allows users to views a map of the U.S. layered with the different faults all across the country. at 00:51 August 13, 2022 UTC, Location: Alabama shakes: Small earthquakes common, potential for big one exists. Because uplift rates associated with large New Madrid earthquakes could not have occurred continuously over geological timescales without dramatically altering the local topography, studies have concluded that the seismic activity there cannot have gone on for longer than 64,000 years, making the New Madrid Seismic Zone (NMSZ) a young feature, or that earthquakes and the associated uplift migrate around the area over time, or that the NMSZ has short periods of activity interspersed with long periods of dormancy. Due to the fault, the blocks can easily move, which is what is happening when an earthquake occurs. That fault was likely responsible for a major earthquake (estimated magnitude 6-7) that occurred near Pensacola, Fla. in 1781, leveling at least one home and shaking ammunition racks from the walls of a barracks. (5.2 miles), 2021-08-21 12:50:14 UTC Although estimates vary widely, the most reliable surveys of casualties indicate that th, The maps presented here provide an update to the 2008 data contained in U.S Geological Survey Scientific Investigations Map 3195 (http://pubs.usgs.gov/sim/3195/).Probabilistic seismic-hazard maps were prepared for the conterminous United States for 2014 portraying peak horizontal acceleration and horizontal spectral response acceleration for 0.2- and 1.0-second periods with probabilities of exceed, In October 2009, two trenches excavated across an 11-kilometer-long scarp at Wenas Valley in central Washington exposed evidence for late Quaternary deformation. Subsequently, the rifted margin was buried beneath the thick, Middle Jurassic, Louann Salt and an overlying, carbonate and clastic, marine sequence that continues to accumulate today. [11], Alabama's abundant natural mineral resources include commercially viable deposits of coal, oil, natural gas, and various minerals such as limestone and marble. As of January 12, 2017, the USGS maintains a limited number of metadata fields that characterize the Quaternary faults and folds of the United States. 19.2 km from (July 17, 2014), "Center for Earthquake Research and Information at the University of Memphis", "Reelfoot rift and its impact on Quaternary deformation in the central Mississippi River valley", "Reelfoot Rift: Reactivated Precursor to the Mississippi Embayment", 10.1130/0016-7606(1975)86<1287:RRRPTT>2.0.CO;2, "Uncovering Hidden Hazards in the Mississippi Valley", "USGS Earthquake Hazards Program, Earthquake Report: Kentucky", 10.1130/0091-7613(2001)029<0175:DDTISI>2.0.CO;2, "Sinking Mafic Body in a Reactivated Lower Crust: A Mechanism for Stress Concentration at the New Madrid Seismic Zone", "Descent of the ancient Farallon slab drives localized mantle flow below the New Madrid seismic zone", "How old is the New Madrid Seismic Zone? The equipment recorded more than 200 earthquakes during that time, ranging from M 0.8 to M 4. This fault line is called the Quaternary fault. The stress field is extensional throughout the post-rift sequence in both the Interior and Coastal zones of the normal-fault belt, as determined mostly from drill-hole data that demonstrate fault slips and well-bore breakouts (Zoback and Zoback, 1991 #2006). 8.2 km from 13.2 km from In the winter of 1811-1812, a series of massive quakes ripped through the southeast Missouri, essentially destroying the town of New Madrid (pronounced mad-rid, not muh-drid), and causing major damage to St. Louis. Epicenter at 34.579, -85.892 Greene County, south of Tuscaloosa, experienced 21 earthquakes in nine months from November 2014 to August 2015, including three separate earthquakes on a single day in February 2015, and a week in May 2015 that saw five earthquakes around Eutaw. (4.2 miles), 2021-11-07 06:12:39 UTC 2.2 km from A recent . [13] About 80km southwest of the presently defined NMSZ, but close enough to be associated with the Reelfoot Rift, near Marianna, Arkansas, two sets of liquefaction features indicative of large earthquakes have been tentatively identified and dated to 3500 and 4800 BC. SDC/Map Color. The geology of Alabama is marked by abundant geologic resources and a variety of geologic structures from folded mountains in the north to sandy beaches along the Gulf of Mexico coast. People in Boston said their buildings swayed. There are now 374 recorded earthquakes in Alabama according to GSA records, dating back to 1886. 18.2 km from Ground shaking is the most powerful predictor of damage from an earthquake. California Department of Conservation. (8.2 miles), 2022-12-04 06:16:37 UTC San Andreas-like fault found in eastern U.S. For years, geologists have been puzzled by a remarkably straight magnetic line that runs between New York and Alabama along the Appalachians. 9.2 km from (3.2 miles), 2022-12-04 10:57:58 UTC Sylacauga The northeast corner of the state is subject to the greatest peak accelerations due to the presence of the East Tennessee Seismic Zone. In 2009, two studies based on eight years of GPS measurements indicated that the faults were moving at no more than 0.2 mm (0.008 in.) Copyright 2023. California Geological Survey. LaFayette Where are the Alabama earthquake fault lines? Epicenter at 35.636, -85.655 Crossing over Transmountain Road and even running along Alabama Street near Northeast El Paso. The strongest is a magnitude 4.7 that struck in 1973. Only List Earthquakes Shown on Map . The 15 May 2020, M6.5 Monte Cristo Range earthquake was the largest earthquake in Nevada in over 66 years and occurred in a sparsely populated area of western Nevada about 74 km southeast of the town of Hawthorne. The movement of the blocks makes the ground shift and shake. Epicenter at 32.874, -86.672 Interactive map of earthquakes in Alabama The Geological Survey of Alabama provides an online interactive map of earthquake information for Alabama. Epicenter at 34.615, -85.29 Earthquake fault lines are a lines that mark all the known (10.2 miles), 2022-01-19 05:33:43 UTC Monday afternoon, a magnitude-3.1 quake hit northeast of Flomaton. at 06:37 April 07, 2021 UTC, Location: The quake damaged the civic building at Henderson, Kentucky, and was felt in 23 states. The New Madrid Seismic Zone (/mdrd/), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri. A 4.0 quake is 100 times more powerful than a 2.0 and so on. In summary, the belt of gulf-margin normal faults in from Florida through Texas has strikingly low historical seismicity; the stress field and seismogenic potential of the underlying crust are unknown; and, therefore, the ability of the fault belt to generate significant seismic ruptures that could cause damaging ground motion is unclear. Epicenter at 34.673, -85.103 1 earthquake in the past 7 days. A map of the fault lines database from the United States Geological Survey. Epicenter at 34.98, -86.619 That area was sparsely populated then (the city of Memphis had not yet been founded), but similar quakes today would cause massive damage, potentially stretching into north Alabama. [6], Since other ancient rifts are known to occur in North America, but not all are associated with modern earthquakes, other processes could be at work to locally increase mechanical stress on the New Madrid faults. Epicenter at 34.601, -85.479 Extensive oil and gas deposits have been developed in the southern portion of the state, Mobile Bay, and coastal state waters. [7][8] The largest earthquake in recorded Alabama history measured an estimated magnitude of 5.1 and occurred October 18, 1916 near Irondale, and resulted in widespread panic, damage to structures, and dramatic changes in water well levels. Epicenter at 34.802, -85.046 in the U.S. east of the Rocky Mountains. Earthquake magnitudes are calculated on a logarithmic scale, so a magnitude 3.0 quake is 10 times more powerful than a 2.0. interpreted the lack of similar signals elsewhere in the chronology as evidence against large New Madrid earthquakes between those years and 1811. (9.2 miles), 2023-02-06 13:24:21 UTC (8.2 miles), 2022-11-22 06:44:43 UTC The map is from a 2007 report (click here to download) on seismic design categories in Washington. A fault is a break in the earth's crust along which movement can take place causing an earthquake. found on websites such as Google Image, Bing Image and Flickr. 5.2 km from Salt flowed southward and pierced upward, and the overlying sediments extended on listric, normal, growth faults that flatten downward into detachments in the salt and in overpressured shales (Ewing, 1991 #1994; Nelson, 1991 #1995). Who makes the plaid blue coat Jesse stone wears in Sea Change? Many of the published accounts describe the cumulative effects of all the earthquakes (known as the New Madrid Sequence), so finding the individual effects of each quake can be difficult. The largest quake to strike Alabama directly was a 5.1 magnitude that hit the Irondale-Easonville area on Oct. 18, 1916. However, there are several intraplate faults running through the state that can cause frequent small earthquakes, and rare larger ones. Format. Escambia County is in the Bahamas Fracture seismic zone, which stretches across Mississippi, lower Alabama, down the western side of Florida toward the Caribbean. at 09:32 May 15, 2022 UTC, Location: [4] The rift failed to split the North American continent, but it has remained as an aulacogen (a scar or zone of weakness) deep underground. [7] Alabama also lies within the influence of the New Madrid Seismic Zone and the South Carolina Seismic Zone, earthquakes in those zones have resulted in damage in Alabama. Accordingly, the fault belt is assigned to class B. 13.2 km from Dalton [33], Reelfoot Rift and the New Madrid Seismic Zone in a 3D topographic image, Magnetic potential map of the Reelfoot Rift, Pages displaying wikidata descriptions as a fallback, Petersen, Mark D.; Moschetti, Morgan P.'; Powers, Peter M.' et al. 200 earthquakes during that time, ranging from M 0.8 to M 4 one exists, Location Alabama...: Alabama shakes: Small earthquakes, and rare larger ones plate, like California from shaking...
