(1.2 miles), 2022-03-30 06:19:59 UTC The recent Virginia [9] Since 1886, slightly more than 10 percent of earthquakes with an epicenter in Alabama have been an estimated magnitude 3 or greater. A .gov website belongs to an official government organization in the United States. 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. American Geologist. The quake damaged the civic building at Henderson, Kentucky, and was felt in 23 states. The amount of shaking an earthquake produces at a particular place depends not only on the earthquake's size, but also local characteristics like the bedrock type and soil type. Alabama spans three continental geologic provinces as defined by the United States Geological Survey, the Atlantic Plain, Appalachian Highlands, and Interior Plains. Ground shaking is the most powerful predictor of damage from an earthquake. [citation needed], The faults responsible for the NMSZ are embedded in a subsurface geological feature known as the Reelfoot Rift, which likely formed during the Cambrian Period. Extensive oil and gas deposits have been developed in the southern portion of the state, Mobile Bay, and coastal state waters.

Magnitude. earthquake, which occurred on Aug. 23, 2011, was not related to any 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. 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 equipment recorded more than 200 earthquakes during that time, ranging from M 0.8 to M 4. 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 34.685, -85.078 LaFayette at 12:08 September 11, 2021 UTC, Location: Sort. (2) The Coastal zone of Ewing (1991 #1994) covers southern Louisiana, coastal Texas, and their offshore extensions, and is separated from the Interior zone by the Early Cretaceous shelf edge (Ewing, 1991 #1994; Ewing and Lopez, 1991 #2032). Alabama, United States has had: (M1.5 or greater) 0 earthquakes in the past 24 hours. See below for an embedded map of all documented Alabama earthquakes dating back to 1886. (3.2 miles), 2021-04-07 06:37:11 UTC Clanton Calculations show that the crustal load from rapid Quaternary sedimentation may aid Quaternary normal faulting and reactivate Tertiary faults of the Coastal zone by imposing extensional bending stresses on the post-rift sequence; older extensional stresses imposed by the Mesozoic sediment load have had time to relax (Nunn, 1985 #2215). rest of the gulf coast. It spans a sequence of four northwest-trending tectonostratigraphic terranes of the Klamath Mountains geologic province that includes, from east to west, the Eastern Hayfork, Western Hayfork, Rattlesnake Creek, and Western Jurassic terranes, as well as, in the southwe, The Hyampom 15' quadrangle lies west of the Hayfork 15' quadrangle in the southern part of the Klamath Mountains geologic province of northern California. Triassic-Jurassic rifting and sedimentation, including deposition of the Louann Salt, led to Mesozoic growth faulting and salt tectonism. [] Reply. 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.. Data for each event are provided. [12] The Cahaba Basin and Black Warrior Basin in central Alabama produce coalbed methane. Maps of these fault lines can be A belt of mostly seaward-facing normal faults borders the northern Gulf of Mexico in westernmost Florida, southwestern Alabama, southern Mississippi, all of Louisiana and southernmost Arkansas, and eastern and southern Texas (Ewing and Lopez, 1991 #2032). (2.2 miles), 2021-08-25 06:19:18 UTC Mississippi line. Lidar data acquired from the U.S. Army's Yakima Training Center reveal a prominent, northwest-side-up, 65- to 70-trending, 3- to 4-meter-high scarp that cuts across the w, Probabilistic seismic-hazard maps were prepared for the conterminous United States portraying peak horizontal acceleration and horizontal spectral response acceleration for 0.2- and 1.0-second periods with probabilities of exceedance of 10 percent in 50 years and 2 percent in 50 years. Due to the fault, the blocks can easily move, which is what is happening when an earthquake occurs. the New York-Alabama Lineament, which is a major magnetic fault 5.2 km from 0.2 km from The Geological Survey of Alabama provides an online interactive map of earthquake information for Alabama. The northeast corner of the state is subject to the greatest peak accelerations due to the presence of the East Tennessee Seismic Zone. That quake was the second largest ever recorded in Alabama, behind an estimated magnitude-5.2 quake that hit northern Shelby County in 1916. All rights reserved (About Us). Based on artifacts found buried by sand blow deposits and from carbon-14 studies, previous large earthquakes like those of 18111812 appear to have happened around AD 1450 and 900,[12] as well as around AD 300. [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 fault could trigger the "Big One" and be followed by a tsunami, according to PHIVOLCS. Epicenter at 34.687, -85.077 The alignment of the scarp and aero, The Boylston Mountains anticlinal ridge is one of several that are cored by rocks of the Columbia River Basalt Group and, with the interceding synclinal valleys, constitute the Yakima fold-and-thrust belt of central Washington. 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. Its now been 207 years since the last major New Madrid seismic event. Epicenter at 34.615, -85.29 There are different types of faults as well including the normal fault, the thrust fault, and strike-slip fault, a left-lateral strike-slip fault and a right-lateral strike-slip fault. Android | iOS version Why is there advertising on this site? Join half a million readers enjoying Newsweek's free newsletters. The map provides the locations, dates, and magnitudes of historical earthquakes, as well as highlighting recent earthquakes. [28] This contrasts to the rate of slip on the San Andreas Fault, which averages up to 37mm (1.5in) a year across California. (7.2 miles), 2021-12-22 06:20:48 UTC Since then, more than 4,000 earthquakes have been recorded, most of which were too small to be felt. There are major and minor fault lines all over the United [1][5] This province is further divided into the Interior Low Plateaus province. 7.2 km from LaFayette This level of seismicity is even less than that of sparsely seismic North and South Dakota, which together cover approximately the same area as the belt of gulf-margin faults and which had seven earthquakes of MMI VI since 1909 (Stover and Coffman, 1993 #1986). earthquakes in an area or region. Trion 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. Interactive map of earthquakes in Alabama The Geological Survey of Alabama provides an online interactive map of earthquake information for Alabama. This earthquake, which occurred Dec. 20 about three miles outside of Bryant, Ala. near the Tennessee border, had a magnitude of just 1.8, meaning it would be very hard to detect without. Aliceville 4.2 km from These features were interpreted to have been caused by groups of large earthquakes timed closely together. All of the maps were prepared by combining the hazard derived from spatially smoothed historic seismicity with th, The Dubakella Mountain 15' quadrangle is located just south of the Hayfork quadrangle and just east of the Pickett Peak quadrangle. On average, one earthquake per year is large enough to be felt in the area. at 02:27 July 18, 2021 UTC, Location: 82 km S of Manokwari, Indonesia. Eocene to Holocene (Szabo and Copeland, 1988 #1946; DuBar and others, 1991 #2010). 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.

A map of the fault lines database from the United States Geological Survey. Trion Owens Cross Roads 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. Thicknesses exceed 12 km under coastal Texas and southern Louisiana and perhaps 16 km offshore Louisiana. The potential for the recurrence of large earthquakes and their effects today on densely populated cities in and around the seismic zone has generated much research devoted to understanding in the NMSZ. Alabama does not rest along the edge of a major tectonic plate, like California. Hazel Green The USGS issued a fact sheet in 2009 stating the estimate of a 710% chance of a New Madrid earthquake of magnitude comparable to one of the 18111812 quakes within the next 50 years, and a 2540% chance of a magnitude 6.0 earthquake in the same time frame. 2.2 km from The GSA reported: "Near the epicenter, chimneys were knocked down, windows. Epicenter at 34.598, -85.456 For information about specific risks in your local area, contact your state geological survey or regional earthquake consortium: Click here to access the National Seismic Hazard maps. The only damaging earthquakes reported through 1989 in this huge tract of land are four MMI VI earthquakes in westernmost Florida (1780), southern Louisiana (1930), and eastern Texas (1891, 1932) (Stover and Coffman, 1993 #1986).

(5.2 miles), 2022-12-24 22:49:49 UTC The 1895 event had its epicenter near Charleston, Missouri. Note that most faults that can affect residents are either onshore or just offshore. 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. at 06:16 December 04, 2022 UTC, Location: Dalton Users can also search the database on faults to learn more about a specific fault. Epicenter at 35.046, -85.128 (8.2 miles), 2022-10-09 05:45:39 UTC However, there are several intraplate faults running through the state that can cause frequent small earthquakes, and rare larger ones. Conclusive evidence of the origin of the Wetumpka Impact Crater was found by Auburn University geology professor David T. King in 1998.[16]. at 11:22 March 14, 2021 UTC, Location: Official websites use .gov Here a map of the major earthquake fault lines in the USA. Stephenson, W.J., K.M. Epicenter at 34.859, -85.547 [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. Source: U.S. Geological Survey Seismic Hazard Maps and Data (2014). This map shows areas of seismic risk from high (red) to low (grayish-green). 8.2 km from Direct economic losses, according to the report, would be at least $300 billion.

Strong shakingDamage negligible in buildings of good design and construction; slight to moderate in well-built ordinary structures; considerable damage in poorly built structures. [3] The Reelfoot Rift was first described by Ervin and McGinnis (1975) and believed to be of late Precambrian age. at 10:57 December 04, 2022 UTC, Location: The 3.1-magnitude quake is also far from the strongest to hit Escambia County or Alabama. 2023-02-12 02:43:51 (UTC-08:00) 44.1 km . 16 earthquakes in the past 365 days. Michael Tuomey, appointed state geologist in 1847, completed a Geological Map of Alabama and in 1849 and published the first of two comprehensive reports on the state's resources a year later. Whitwell 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. reason i say this , is because the other night on [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. 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. Copyright 2023. 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. Accordingly, the fault belt is assigned to class B. [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. The Hayward Fault in California is the most dangerous earthquake fault in the USA and the single most urbanized earthquake fault in the United States - Stiri mobil stiri video stiri online pariuri1x2 Mar 29, 2018 At 3:03 pm [] Here a map of the major earthquake fault . 14.2 km from (6.2 miles). The strongest earthquake in Alabama today occurred 19 hours ago: Minor mag. Alabama shakes: Small earthquakes common, potential for big one exists. With all the pressure of the continents that are actually still moving around, theyre bumping into each other and pulling apart from each other in certain places, all of that kind of adds up stress along those weak zones, Ebersole said. Tap/click on "gear icon" for options and settings. 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. These maps are used in determining building seismic codes, insurance rates, and other There are now 374 recorded earthquakes in Alabama according to GSA records, dating back to 1886. a Thursday we felt a tremor that shook the place, no one else knew (6.2 miles), 2022-09-04 21:51:08 UTC Escambia County is in the Bahamas Fracture seismic zone, which stretches across Mississippi, lower Alabama, down the western side of Florida toward the Caribbean. [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. California Department of Conservation. 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). [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. 4.2 km from Because numerous individual faults are combined into a single group for this compilation, it is not possible to provide to provide digital information about the azimuth, length, and dip of each individual fault. The most recent quake registered as a magnitude 4.4, just slightly less than the biggest one that part of Tennessee has ever seen. [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. [3][5], This relative weakness is important, because it would allow the relatively small eastwest compressive forces associated with the continuing westward continental drift of the North American Plate to reactivate old faults around New Madrid, making the area unusually prone to earthquakes in spite of it being far from the nearest tectonic plate boundary. Gulf-margin normal faults, Alabama and Florida (Class B) No. Tap/click on "gear icon" for options and settings. [3], Alabama experiences frequent small earthquakes detectable only by instruments, and occasional moderate earthquakes large enough to be felt over a wide area and resulting in minor damage. at 13:24 February 06, 2023 UTC, Location: The largest earthquakes to have occurred since then were on January 4, 1843, and October 31, 1895, with magnitude estimates of 6.0 and 6.6, respectively.
