These maps are used in determining building seismic codes, insurance rates, and other Where are the Alabama earthquake fault lines? at 10:16 August 13, 2022 UTC, Location: (1) The Interior zone of Ewing (1991 #1994) includes the entire belt except southern Louisiana, coastal Texas, and their offshore extensions. at 00:51 August 13, 2022 UTC, Location: Featured at the top are our most popular interactive maps, but there are more USGS map publications, listed below on this page. Ground shaking is the most powerful predictor of damage from an earthquake. (11.2 miles), 2021-11-06 06:50:03 UTC The period passed with no major earthquake activity in New Madrid or along the 120-mile (190km) fault line. [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 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. Stephenson, W.J., K.M. [3] The Reelfoot Rift was first described by Ervin and McGinnis (1975) and believed to be of late Precambrian age. There's one database for Class A and B faults and another for Class C and D faults. Kimball Earthquake magnitudes are calculated on a logarithmic scale, so a magnitude 3.0 quake is 10 times more powerful than a 2.0. The equipment recorded more than 200 earthquakes during that time, ranging from M 0.8 to M 4. 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. [28] Seth Stein, the leader of the research group, published these views in a book, Disaster Deferred, in 2008. at 06:50 November 06, 2021 UTC, Location: The recent Virginia Primarily designed for use by earth scientists, engineers, and educators, this map provides a comprehensive overview of strong (magnitude [M] 5.5 and larger) earthquakes since 1900. It also covers a part of West Tennessee, near Reelfoot Lake, extending southeast into Dyersburg. See here for older maps for Alaska, Hawaii, and U.S. territories. Epicenter at 34.687, -85.077 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. [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 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. 1 earthquake in the past 7 days. There hasn't been a major earthquake since 1916. (6.2 miles), 2022-08-13 10:16:53 UTC 2023 Advance Local Media LLC. Newest First. Ground shaking is the most powerful predictor of damage from an earthquake. Why were Mexican workers able to find jobs in the Southwest? 5.2 km from Strong shakingDamage negligible in buildings of good design and construction; slight to moderate in well-built ordinary structures; considerable damage in poorly built structures. [28] This contrasts to the rate of slip on the San Andreas Fault, which averages up to 37mm (1.5in) a year across California.

The two biggest fault lines that run through North Carolina 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. Epicenter at 35.636, -85.655 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. 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. The movement of the blocks makes the ground shift and shake. McMinnville 5.2 km from The interactive map to below shows epicenters of historical Alabama earthquakes since 1886 and surface and basement faults. 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. at 09:32 May 15, 2022 UTC, Location: The largest quake to strike Alabama directly was a 5.1 magnitude that hit the Irondale-Easonville area on Oct. 18, 1916. 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. The post-rift sequence and its belt of gulf-margin normal faults may be mechanically decoupled from the underlying crust. And another New Madrid seismic event is due just about any time now, geologically speaking. On March 6, a magnitude-2.6 earthquake was recorded near Century, Florida, close to the Alabama border. That quake was the second largest ever recorded in Alabama, behind an estimated magnitude-5.2 quake that hit northern Shelby County in 1916. (8.2 miles), 2022-11-22 06:44:43 UTC Epicenter maps show only sparse, low-magnitude seismicity within the fault belt (Engdahl, 1988 #1959; Stover and Coffman, 1993 #1986). Conclusive evidence of the origin of the Wetumpka Impact Crater was found by Auburn University geology professor David T. King in 1998.[16].

What is A person who sells flower is called? Who makes the plaid blue coat Jesse stone wears in Sea Change? Alabama shakes: Small earthquakes common, potential for big one exists. Triassic-Jurassic rifting and sedimentation, including deposition of the Louann Salt, led to Mesozoic growth faulting and salt tectonism. Epicenter at 34.708, -85.285 A fault line called the Pollard Fault System runs through the area of Escambia County, connecting with the Foshee Fault System in Florida. Official websites use .gov Faults with evidence of Holocene (about 10,000 . [7][8] Also, some form of heating in the lithosphere below the area has been suggested to be making deep rocks more plastic, which would concentrate compressive stress in the shallower subsurface area where the faulting occurs.[9][10]. YouTubes privacy policy is available here and YouTubes terms of service is available here. "And from what they've been able to determine is that these events occur on an average cycle of 200-300 years.". (1995). The GSA reported: "Near the epicenter, chimneys were knocked down, windows. There is one major fault line that runs through Alabama and the rest of the gulf coast. Regional fluctuations in the overall deposition rate divide the belt of gulf-margin faults into two parts with different main ages of faulting and different degrees of Quaternary faulting. There hasn't been a major earthquake since. at 22:05 January 22, 2021 UTC, Location: (1.2 miles), 2022-03-30 06:19:59 UTC Android | iOS version Why is there advertising on this site? 20, p. 207, "East Gulf Coastal Plain Ecoregional Plan", https://en.wikipedia.org/w/index.php?title=Geology_of_Alabama&oldid=1106112936, Articles with dead external links from January 2017, Articles with permanently dead external links, Articles with dead external links from November 2018, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 23 August 2022, at 07:29. There are major and minor fault lines all over the United Cookie Settings/Do Not Sell My Personal Information. And then you have little shifts and thats what ends up initiating your earthquakes.. Also, generalized fault data used in the hazard maps. [13], The first scientific reports of Alabama's geology were made during field studies by R. T. Brumby in the late 1830s and Sir Charles Lyell in the early 1840s. 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. 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. Whitwell 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. 4.2. . C/Yellow. American Geologist. However, there are several intraplate faults running through the state that can cause frequent small earthquakes, and rare larger ones. #1806 Chang, T.M., Ammon, C.J., and Herrmann, R.B., 1998, Faulting parameters of the October 24, 1997 southern Alabama earthquake [abs. 2023-02-12 02:43:51 (UTC-08:00) 44.1 km . [3], The broad, flat coastal plain stretches across the southern portion of the state, extending north from the Gulf coast to the Fall Line near Montgomery, Alabama. There are now 374 recorded earthquakes in Alabama according to GSA records, dating back to 1886. at 11:22 March 14, 2021 UTC, Location: Hazel Green 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. 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. 3.2 km from 10.2 km from 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). The northeast corner of the state is subject to the greatest peak accelerations due to the presence of the East Tennessee Seismic Zone. [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. The USGS and its partners monitor and report earthquakes, assess earthquake impacts and hazards, and perform research into the causes and effects of earthquakes. The major earthquake and large aftershock in Turkey on Monday are two of more than 70 quakes of magnitude 6.5 or higher recorded in the region since 1900. at 22:49 December 24, 2022 UTC, Location: This post-rift sequence thickens seaward (Salvador, 1991 #2020).

Epicenter at 34.685, -85.078 Alabama's fault lines cause frequent small earthquakes, but have the potential to cause much more damage. at 05:33 January 19, 2022 UTC, Location: Three quakes so close together might qualify as unusual, but its hardly unprecedented. earthquakes in an area or region. what type of danger zone is needed for this exercise. California Department of Conservation. On this Wikipedia the language links are at the top of the page across from the article title. [1], Earthquakes that occur in the New Madrid Seismic Zone potentially threaten parts of seven American states: Illinois, Indiana, Missouri, Arkansas, Kentucky, Tennessee, and Mississippi.[2]. at 17:09 August 21, 2022 UTC, Location: 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). [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. The data behind it was acquired in the early hours of Friday by the European Union's Sentinel-1A satellite as it traversed north to south over Turkey at an altitude of 700km (435 miles).

The map provides the locations, dates, and magnitudes of historical earthquakes, as well as highlighting recent earthquakes. The 1895 event had its epicenter near Charleston, Missouri. 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). Clanton 13.2 km from The map also shows potentially active faults from a separate 2014 report (click here to download). What is the Denouement of the story a day in the country? major geological fault line. The fault runs along the east side of the Franklins. 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). In a report filed in November 2008, the U.S. Federal Emergency Management Agency warned that a serious earthquake in the NMSZ could result in "the highest economic losses due to a natural disaster in the United States," further predicting "widespread and catastrophic" damage across Alabama, Arkansas, Illinois, Indiana, Kansas, Kentucky, Mississippi, Missouri, Oklahoma, Texas, and particularly Tennessee, where a 7.7 magnitude quake would cause damage to tens of thousands of structures affecting water distribution, transportation systems, and other vital infrastructure. Alabama spans three continental geologic provinces as defined by the United States Geological Survey, the Atlantic Plain, Appalachian Highlands, and Interior Plains. Aliceville Note: Beginning in 2016, the U.S. Geological Survey has produced an annual seismic hazard map for the central and eastern United States that includes induced earthquakes. at 18:01 April 21, 2022 UTC, Location: The map provides the locations, dates, and magnitudes of historical earthquakes, as well as highlighting recent earthquakes. 10.2 km from 16 earthquakes in the past 365 days. 18.2 km from For the most up-to-date information, please refer to the interactive fault map. Map showing recorded earthquakes in Alabama and the seismic zones that cause them. The three earthquakes recorded near the Alabama-Florida state line since March 6 are part of the normal seismic activity, of the area, according to the director of Alabamas Geological Investigations Program. A recently active fault strand is defined here as having evidence consistent with slip during the Holocene epoch (approxim, The magnitude (M) 7.0 Haiti earthquake of January 12, 2010, triggered landslides throughout much of Haiti on the island of Hispaniola in the Caribbean Sea. Earthquake scenarios describe the expected ground motions and effects of specific hypothetical large earthquakes. Since 1812, frequent smaller earthquakes have been recorded in the area. at 05:45 October 09, 2022 UTC, Location: A map of the fault lines database from the United States Geological Survey. Format. Sylvania [27], The lack of apparent land movement along the New Madrid fault system has long puzzled scientists. 4.2 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).

[11], Alabama's abundant natural mineral resources include commercially viable deposits of coal, oil, natural gas, and various minerals such as limestone and marble. Earthquake Hazard. ]: Seismological Research Letters, v. 69, p. 175-176. To read more information on individual earthquakes or faults, click the feature on the map. These features were interpreted to have been caused by groups of large earthquakes timed closely together. [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. [31], According to the USGS, a broad consensus exists that the possibility of major earthquakes in the NMSZ remains a concern, and that the GPS data do not provide a compelling case for lessening perceived earthquake hazards in the region. A line of large grabens approximates the landward limit of Jurassic salt, and Cenozoic faulting is sparse in the Interior zone (Ewing, 1991 #1994; Salvador, 1991 #2019; Ewing and Lopez, 1991 #2032).

Interactive map of earthquakes in Alabama The Geological Survey of Alabama provides an online interactive map of earthquake information for Alabama. Copyright 2023. A 2009 study estimated that a 7.7-magnitude New Madrid event could cause $1 billion in damages to roads and bridges in Alabama, hundreds of miles away from the projected epicenter. 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. It is southwest of the Wabash Valley Seismic Zone. One concern is that the small earthquakes that still happen are not diminishing over time, as would be if they were aftershocks of the 18111812 events; another is that the 4,500-year archaeological record of large earthquakes in the region is more significant than 10 years of direct strain measurement.
