National Earthquake Hazards Reduction Program (NEHRP). "[27] Despite the lack of scientific support, Browning's prediction was widely reported in international media, causing public alarm. 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). 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.. Ground shaking is the most powerful predictor of damage from an earthquake. 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. reason i say this , is because the other night on [] Reply. at 10:57 December 04, 2022 UTC, Location: Epicenter at 35.134, -85.716 View Earthquake Map Faults Interactive fault map and comprehensive geologically based information on known or suspected active faults and folds in the United States. at 22:49 December 24, 2022 UTC, Location: Everyone Practices Cancel Culture | Opinion, Deplatforming Free Speech is Dangerous | Opinion, 4.4 Magnitude Earthquake Rumbled Tennessee, Says USGS, East Antartica Glaciers Melting at 'Systematic' Rate. [26][27] Browning appears to have based this prediction on particularly strong tidal forces being expected during that time, and his opinion that a New Madrid earthquake was "overdue;" however, seismologists generally agree that no correlation exists between tides and earthquakes. Depth and magnitude of quakes versus time plot Interactive map Try our free app! [12] The Cahaba Basin and Black Warrior Basin in central Alabama produce coalbed methane. Therefore, the natural seismicity rate in the normal-fault belt might be even less than the recent historical record would indicate. at 06:44 November 22, 2022 UTC, Location: 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). 14.2 km from If you live in a high-risk area or near a fault line in the Philippines, go beyond doing the duck, cover, and hold. at 06:37 April 07, 2021 UTC, Location: Sylacauga 18.2 km from Source: U.S. Geological Survey Seismic Hazard Maps and Data (2014). at 06:19 March 30, 2022 UTC, Location: The U.S. Geological Survey (USGS) National Seismic Hazard Map shows the strength of ground shaking that has a 1 in 50 chance of being exceeded in a particular place in the lower 48 states over a period of 50 years. On this Wikipedia the language links are at the top of the page across from the article title. In early to middle Mesozoic time, the opening of the Gulf of Mexico formed a south-facing, rifted, passive margin at the southern edge of North America (DuBar and others, 1991 #2010; Salvador, 1991 #2019; Salvador, 1991 #2020). What is A person who sells flower is called? 5.2 km from Magnitude. A teacher walks into the Classroom and says If only Yesterday was Tomorrow Today would have been a Saturday Which Day did the Teacher make this Statement? Booneville Rapid deposition and the resulting enormous thickness of the post-rift sediments caused them to collapse and spread seaward. major fault lines that you need to worry about. Earthquake scenarios describe the expected ground motions and effects of specific hypothetical large earthquakes. The 1895 event had its epicenter near Charleston, Missouri. Epicenter at 34.859, -85.547 We do have episodes of this kind of seismic activity clusters once in a while, Ebersole said. Conclusive evidence of the origin of the Wetumpka Impact Crater was found by Auburn University geology professor David T. King in 1998.[16]. 2023-02-24 07:37:18 UTC Monday afternoon, a magnitude-3.1 quake hit northeast of Flomaton. The map also shows potentially active faults from a separate 2014 report (click here to download). Mississippi line. 4.2 km from Sort. A fault line called the Pollard Fault System runs through the area of Escambia County, connecting with the Foshee Fault System in Florida. Potential Effects of Shaking. A 4.0 quake is 100 times more powerful than a 2.0 and so on. (3.2 miles), 2022-08-13 00:51:51 UTC A .gov website belongs to an official government organization in the United States. Faults can also move slowly and when they do, they don't cause the rapid or violent movement that a slip or a quick movement can cause. 1 earthquake in the past 7 days. The map provides the locations, dates, and magnitudes of historical earthquakes, as well as highlighting recent earthquakes. Seriously, check here first. GIS shapefiles and metadata: Geospatial Hazards Data page. All information managed by the Geological Survey of Alabama. California Geological Survey. [32], In July 2014, the USGS increased the risk assessment for the New Madrid area.

Epicenter at 33.201, -86.11 A guidebook to tracing the fault on public lands in the San Francisco Bay region; 2006; GIP; 16; Stoffer, Philip W. This fault line is called the Quaternary fault. This almighty quake caused extensive damage to the transportation systems in central Alaska. three earthquakes recorded near the Alabama-Florida, magnitude-2.6 earthquake was recorded near Century, Florida, U.S. Geological Surveys self-reporting tool, Buy newspaper front pages, posters and more. earthquake, which occurred on Aug. 23, 2011, was not related to any The earthquake produced surface rupture distributed across a 28-km-long zone along the eastward projection of the Candelaria fault in the Mina deflection of the central Walker Lane. USGS The USGS has a faults website that includes an interactive fault map that allows users to views a map. What are the disadvantages of shielding a thermometer? By studying evidence of past quakes and closely monitoring ground motion and current earthquake activity, scientists attempt to understand their causes and recurrence intervals. 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. 4.2 km from You are planning an exercise that will include the m16 and m203. 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. Thorsby On Wednesday, a 2.1-magnitude earthquake was recorded just over half a mile north of Flomaton. The fault runs along the east side of the Franklins. Tennessee, Arkansas, and Missouri would be most severely impacted, and the cities of Memphis, Tennessee, and St. Louis, Missouri, would be severely damaged. Tap/click on "gear icon" for options and settings. 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. [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. Dalton The fault could trigger the "Big One" and be followed by a tsunami, according to PHIVOLCS. 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. These publications did much to quantify the mineral wealth of the Birmingham District and helped establish the region's early iron industry. Earthquake magnitudes are calculated on a logarithmic scale, so a magnitude 3.0 quake is 10 times more powerful than a 2.0. Epicenter at 34.615, -85.29 The report found that there would be significant damage in the eight states studied Alabama, Arkansas, Illinois, Indiana, Kentucky, Mississippi, Missouri, and Tennessee with the probability of additional damage in states farther from the NMSZ. [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. [1][2] The Geological Survey of Alabama breaks these provinces down into more specific physiographic provinces. (10.2 miles), 2021-03-14 11:22:09 UTC 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. On average, one earthquake per year is large enough to be felt in the area. This fault line is called the Quaternary 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. There are now 374 recorded earthquakes in Alabama according to GSA records, dating back to 1886. Latest Earthquakes Latest earthquakes map and list (past 24 hours, M2.5+) from the ANSS (Advanced National Seismic System). [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. Kimball [28] Seth Stein, the leader of the research group, published these views in a book, Disaster Deferred, in 2008. [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. a Thursday we felt a tremor that shook the place, no one else knew The GSA reported: "Near the epicenter, chimneys were knocked down, windows. C/Yellow. "Thats normal seismic activity for our area.. Epicenter at 35.556, -86.55 The post-rift sequence as a whole is at least 9-11 km thick throughout the Coastal zone (Salvador, 1991 #2020). 4.2. . (9.2 miles), 2021-10-13 20:22:15 UTC The quake damaged virtually all the buildings in Charleston, created sand volcanoes by the city, cracked a pier on the Cairo Rail Bridge, and toppled chimneys in St. Louis, Missouri; Memphis, Tennessee; Gadsden, Alabama; and Evansville, Indiana.[22].

Memphis, TN, Center for Earthquake Research and Information (CERI) comprehensive references for the 18111812 earthquakes, Space geodetic evidence for rapid strain rates in the New Madrid seismic zone of Central USA (PDF), https://en.wikipedia.org/w/index.php?title=New_Madrid_Seismic_Zone&oldid=1136422696. Note that most faults that can affect residents are either onshore or just offshore. East Franklin Mountain Fault Courtesy of Dr. Jose Hurtado. The period passed with no major earthquake activity in New Madrid or along the 120-mile (190km) fault line. In 1997, the a magnitude-4.9 earthquake was recorded northeast of Atmore. 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. There's also a frequently asked questions section of the USGS site solely for fault and earthquake information. (3.2 miles), 2022-12-04 10:57:58 UTC (1) The Interior zone of Ewing (1991 #1994) includes the entire belt except southern Louisiana, coastal Texas, and their offshore extensions. Epicenter at 34.685, -85.078 According to the U.S. Geological Surveys self-reporting tool, the 3.1-magnitude quake was detected as far away as Mobile and Pensacola. Epicenter at 35.296, -85.484 (1.2 miles), 2022-03-30 06:19:59 UTC (3.2 miles), 2022-05-15 09:32:06 UTC Clanton Only List Earthquakes Shown on Map . earthquakes in an area or region. 14.2 km from The interactive map to below shows epicenters of historical Alabama earthquakes since 1886 and surface and basement faults. [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]. Cookie Settings/Do Not Sell My Personal Information. The epicenter of the quake was located at 18.44N., 72.57W. The recent Virginia Aliceville #1806 Chang, T.M., Ammon, C.J., and Herrmann, R.B., 1998, Faulting parameters of the October 24, 1997 southern Alabama earthquake [abs. To reflect regional differences in the characteristics of the faults, those in Florida and Alabama (described here) are evaluated together in a single group, as are those in Mississippi, those in Louisiana and Arkansas, and those in Texas. Earthquakes occur nearly every day in Washington. Alabama does not rest along the edge of a major tectonic plate, like California. Alabama shakes: Small earthquakes common, potential for big one exists. Epicenter at 32.784, -86.766 11.2 km from Those faults date back millions of years, to the Jurassic and Cretaceous periods, when the supercontinent Pangea split into the continents as we know them today. The map is from a 2007 report (click here to download) on seismic design categories in Washington. Triassic-Jurassic rifting and sedimentation, including deposition of the Louann Salt, led to Mesozoic growth faulting and salt tectonism. Trenton Lakesite 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). (8.2 miles), 2022-12-04 06:16:37 UTC at 05:45 October 09, 2022 UTC, Location: LaFayette There are major and minor fault lines all over the United 2.2 km from If you purchase a product or register for an account through one of the links on our site, we may receive compensation. In Alabama, this province generally lies north of the Tennessee River. 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). A strike-slip fault is when two blocks slip past one another, like the San Andreas Fault line. Users can also search the database on faults to learn more about a specific fault. Earthquake Hazard. Its now been 207 years since the last major New Madrid seismic event. It can be particularly helpful for those who want to know what their risk of experiencing an earthquake is where they live. [11], Alabama's abundant natural mineral resources include commercially viable deposits of coal, oil, natural gas, and various minerals such as limestone and marble. LaFayette Official websites use .gov [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. [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]. at 07:37 February 24, 2023 UTC, Location: Aftershocks strong enough to be felt occurred until 1817. Epicenter at 34.673, -88.515 interpreted the lack of similar signals elsewhere in the chronology as evidence against large New Madrid earthquakes between those years and 1811. at 06:42 December 04, 2022 UTC, Location: Article title are either onshore or just offshore and helped establish the region 's early industry...
