Share Settings View Earthquake Map Faults Interactive fault map and comprehensive geologically based information on known or suspected active faults and folds in the United States. Escambia County is in the Bahamas Fracture seismic zone, which stretches across Mississippi, lower Alabama, down the western side of Florida toward the Caribbean. Magnitude estimates and epicenters are based on interpretations of historical accounts and may vary. The presence of the normal faults throughout the post-rift sequence from westernmost Florida to southern Texas (Ewing and Lopez, 1991 #2032) demonstrates that the sequence is sliding and extending seaward on detachments in weak salt and overpressured shales. 2.2 km from (1995). Data for each event are provided. (8.2 miles), 2022-12-04 08:07:27 UTC California Department of Conservation. [27], The lack of apparent land movement along the New Madrid fault system has long puzzled scientists. Smith, Eugene Allen (October 1897) "Sketch of the Life of Michael Tuomey". These publications did much to quantify the mineral wealth of the Birmingham District and helped establish the region's early iron industry. [14], Dendrochronology (tree ring) studies conducted on the oldest bald cypress trees growing in Reelfoot Lake found evidence of the 18111812 series in the form of fractures followed by rapid growth after their inundation, whereas cores taken from old bald cypress trees in the St. Francis sunklands showed slowed growth in the half century that followed 1812. at 07:37 February 24, 2023 UTC, Location: Since then, more than 4,000 earthquakes have been recorded, most of which were too small to be felt. Click here to access the interactive earthquake map of Alabama. at 12:50 August 21, 2021 UTC, Location: at 06:50 November 06, 2021 UTC, Location: 13.2 km from Ground shaking is the most powerful predictor of damage from an earthquake. 18.2 km from 0.2 km from The Geological Survey of Alabama provides an online interactive map of earthquake information for Alabama. Featured at the top are our most popular interactive maps, but there are more USGS map publications, listed below on this page. Epicenter at 35.226, -85.073 7.2 km from C/Yellow. Late Cretaceous and especially Cenozoic clastic sediments prograded southward led to abundant Cenozoic and continuing growth faulting and salt tectonism (for example DuBar and others, 1991 #2010, p. 584-585; Salvador, 1991 #2019). interpreted the lack of similar signals elsewhere in the chronology as evidence against large New Madrid earthquakes between those years and 1811. The largest NMSZ earthquake of the 20th century was a 5.4-magnitude quake (although it was reported as a 5.5 at the time) on November 9, 1968, near Dale, Illinois. [10], Two fault zones are found in Alabama, the Southern Appalachian Seismic Zone (also known as the Eastern Tennessee Seismic Zone) in northeast and central Alabama, and the Bahamas Fracture Seismic Zone in southwest Alabama. 14.2 km from line that runs from New York to Alabama. rest of the gulf coast. Here a map of the major earthquake fault lines in the USA. [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. [23] In 2008 in the nearby Wabash Valley Seismic Zone, a similar magnitude 5.4 earthquake occurred with its epicenter in Illinois near West Salem and Mount Carmel. (3.2 miles), 2021-04-07 06:37:11 UTC Could experience strong shaking. are the Hayesville-Fries fault line and the Brevard Fault. All rights reserved. Epicenter at 34.683, -85.074 Faults with evidence of Holocene (about 10,000 . The gulf-margin normal faults in Alabama and Florida are assigned as Class B structures because their low seismicity and because they may be decoupled from underlying crust, making it unclear if they can generate significant seismic ruptures that could cause damaging ground motion. Earthquakes of mbLg 3.4 and 3.9 and M of 4.0 and 4.7 in southeastern Texas and M 4.9 in southwestern Alabama may have been induced by extraction of oil and gas or injection of fluids for secondary recovery (Pennington and others, 1986 #1876; Chang and others, 1998 #1806; Gomberg and others, 1998 #1828; Gomberg and Wolf, 1999 #3440). Epicenter at 35.169, -85.44 See the Related Link below for more information on fault lines [15], The first known written record of an earthquake felt in the NMSZ was from a French missionary traveling up the Mississippi with a party of explorers. Only List Earthquakes Shown on Map . Ebersole said those faults are the result of stresses from inside the plate, where geologic forces tried to break the plate apart, or fold it over on itself, but were not strong enough. 7.2 km from 13.2 km from This almighty quake caused extensive damage to the transportation systems in central Alaska. (2.2 miles), 2021-09-11 12:08:51 UTC Epicenter at 34.98, -86.619 [14][15], A meteor crater over five miles in diameter was identified near Wetumpka, Alabama in 19691970. The various colors and line types indicate different ages of the most recent earthquakes on the fault and how well the location of the fault is constrained. "A fault that could potentially slip in modern times. 5.2 km from There is one major fault line that runs through Alabama and the rest of the gulf coast. major fault lines that you need to worry about. The recent Virginia [12] The Cahaba Basin and Black Warrior Basin in central Alabama produce coalbed methane. [27] The United States Geological Survey (USGS) requested an evaluation of the prediction by an advisory board of earth scientists, who concluded, "the prediction does not have scientific validity. The map is from a 2007 report (click here to download) on seismic design categories in Washington. The fault could trigger the "Big One" and be followed by a tsunami, according to PHIVOLCS. Since 1812, frequent smaller earthquakes have been recorded in the area. [24] The earthquake is expected to also result in many thousands of fatalities, with more than 4,000 of the fatalities expected in Memphis alone. A fault is a break in the earth's crust along which movement can take place causing an earthquake. in the U.S. east of the Rocky Mountains. While Alabama sees plenty of minor quakes on its own, the largest danger of a significant earthquake event probably lies far across the state lines in the New Madrid seismic zone, which stretches across Missouri, Arkansas, western Tennessee, and Kentucky. If you live in a high-risk area or near a fault line in the Philippines, go beyond doing the duck, cover, and hold. Did You Feel It? The USGS and its partners monitor and report earthquakes, assess earthquake impacts and hazards, and perform research into the causes and effects of earthquakes. Earthquakes occur nearly every day in Washington. Sandy Ebersole, who heads the division of the Geological Survey of Alabama that documents and studies earthquakes in the state, said its not unusual or surprising to have multiple small-scale earthquakes in quick succession in the state. [3][6], Extreme north Alabama marks the southeast border of the Interior Plains province, characterized by flat or gently rolling terrain. [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. [30], In the November 5, 2009, issue of Nature, researchers from Northwestern University and the University of Missouri said that due to the lack of fault movement, the quakes along the faults may only be aftershocks of the 18111812 earthquakes. SDC/Map Color. Epicenter at 34.66, -86.399 Epicenter at 32.784, -86.766 Epicenter at 34.579, -85.892 The. [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. It is at least 2 km thick everywhere in the belt of gulf-margin normal faults. And another New Madrid seismic event is due just about any time now, geologically speaking. States. The post-rift sequence as a whole is at least 9-11 km thick throughout the Coastal zone (Salvador, 1991 #2020). [11], Alabama's abundant natural mineral resources include commercially viable deposits of coal, oil, natural gas, and various minerals such as limestone and marble. At 1 pm on Christmas Day 1699, at a site near the present-day location of Memphis, the party was startled by a short period of ground shaking. Accordingly, the fault belt is assigned to class B. 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. Hazel Green at 05:45 October 09, 2022 UTC, Location: The 2003 Bingl earthquake at magnitude of 6.4 followed before the 2010 (6.1) and 2020 (6.7) quakes which both happened in Elaz. Although some of these ideas have gained some acceptance among researchers, they have not been accepted by the National Earthquake Prediction Evaluation Council, which advises the USGS. 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. These maps are used in determining building seismic codes, insurance rates, and other Interactive Earthquake Map of AL Earthquakes are not uncommon in Alabama. What are the disadvantages of a clapper bridge? Three quakes so close together might qualify as unusual, but its hardly unprecedented. [9] Since 1886, slightly more than 10 percent of earthquakes with an epicenter in Alabama have been an estimated magnitude 3 or greater. 2023-02-24 07:37:18 UTC Epicenter at 32.957, -88.046 (3.2 miles), 2022-12-04 10:57:58 UTC 16.2 km from At the coastline, the sequence is at least 10 km thick west of the Mississippi River and at least 5 km thick farther east. The strongest earthquake in state history, it registered an estimated Richter scale magnitude of 5.1 and resulted in extensive, but minor damage. 4.2. . The movement of the blocks makes the ground shift and shake. at a depth of 13 kilometers (km) approximately 25 km southwest of the capital, Port-au-Prince. 82 km S of Manokwari, Indonesia. The New Madrid Seismic Zone (/ m d r d /), 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.. That quake was the second largest ever recorded in Alabama, behind an estimated magnitude-5.2 quake that hit northern Shelby County in 1916. USGS scientists update these maps as they get more data and their knowledge about earthquake hazards improves. at 12:08 September 11, 2021 UTC, Location: Privacy Policy, West Virginia Geological & Economic Survey, Interactive map of California earthquake hazard zones, Interactive map of geothermal resources in West Virginia, Interactive map of natural hazards in Nevada, Interactive map of earthquakes around the world, Interactive map of earthquakes in Montana, Visualization of earthquake risk in California. 1 earthquake in the past 7 days. There is one major fault line that runs through Alabama and the In 1997, the a magnitude-4.9 earthquake was recorded northeast of Atmore. Epicenter at 35.296, -85.484 LaFayette Clicking on each dot will display additional information about the quake. Its now been 207 years since the last major New Madrid seismic event. These gulf-margin faults face southwest in westernmost Florida, southwestern Alabama, and southern Mississippi; south in Louisiana and southernmost Arkansas; and southeast in eastern and southern Texas (Ewing and Lopez, 1991 #2032). The map provides the locations, dates, and magnitudes of historical earthquakes, as well as highlighting recent earthquakes. 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. A recent . Strong shakingDamage negligible in buildings of good design and construction; slight to moderate in well-built ordinary structures; considerable damage in poorly built structures.

[32], In July 2014, the USGS increased the risk assessment for the New Madrid area. The map clearly identifies the locations of the great earthquakes (M8.0 and larger) and the, This report provides trench photomosaics, logs and related site information, age data, and earthquake event evidence from three paleoseismic trench sites on the Bear River Fault Zone. Epicenter at 35.134, -85.716 USGS The USGS has a faults website that includes an interactive fault map that allows users to views a map. The New Madrid fault system was responsible for the 181112 New Madrid earthquakes, and has the potential to produce large earthquakes in the future. at 06:42 December 04, 2022 UTC, Location: Note that most faults that can affect residents are either onshore or just offshore. (6.2 miles), 2021-07-18 02:27:29 UTC California Geological Survey. These listric normal faults, their splays, and their antithetic and transfer faults make up the belt of gulf-margin normal faults described here.

(11.2 miles), 2021-11-06 06:50:03 UTC Earthquake Hazard in the New Madrid Seismic Zone Remains a Concern USGS (2009). These features were interpreted to have been caused by groups of large earthquakes timed closely together. There are major and minor fault lines all over the United The orientations of Shmin are radial to the Gulf of Mexico, in contrast to the east-northeast trends of SHmax that characterize most of North America east of the Rocky Mountains; the stress field in the crust beneath the thick post-rift sequence is unknown (Zoback and Zoback, 1991 #2006).
