Therefore, the natural seismicity rate in the normal-fault belt might be even less than the recent historical record would indicate. Click here to access the interactive earthquake map of Alabama. Epicenter at 32.874, -86.672 Lakesite 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. The largest quake to strike Alabama directly was a 5.1 magnitude that hit the Irondale-Easonville area on Oct. 18, 1916. 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. 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. LaFayette It also covers a part of West Tennessee, near Reelfoot Lake, extending southeast into Dyersburg. (8.2 miles), 2022-12-04 08:07:27 UTC (3.2 miles), 2022-08-21 17:09:31 UTC 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). rest of the gulf coast. The strongest earthquake in Alabama today occurred 19 hours ago: Minor mag. On Wednesday, a 2.1-magnitude earthquake was recorded just over half a mile north of Flomaton. Also, generalized fault data used in the hazard maps. Advanced National Seismic System Latest earthquakes map and list (past 24 hours, M2.5+). 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. 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. Epicenter at 35.636, -85.655 #1806 Chang, T.M., Ammon, C.J., and Herrmann, R.B., 1998, Faulting parameters of the October 24, 1997 southern Alabama earthquake [abs. This fault line is called the Quaternary a Thursday we felt a tremor that shook the place, no one else knew "Thats normal seismic activity for our area.. Post, This map illustrates 119 years of global seismicity in the context of global plate tectonics and the Earths physiography. at 06:19 March 30, 2022 UTC, Location: Lakesite [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. 2.2 km from The 1916 Irondale earthquake struck in the north-central region of the U.S. state of Alabama on October 18. All rights reserved. However, there are several intraplate faults running through the state that can cause frequent small earthquakes, and rare larger ones. Earthquake scenarios describe the expected ground motions and effects of specific hypothetical large earthquakes. 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 34.764, -84.942 Dalton 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. 10.2 km from 2023-02-12 02:43:51 (UTC-08:00) 44.1 km .

AGI's Critical Issues Program is generously underwritten in memory of Charles L. Weiner. major geological fault line. [3] The Reelfoot Rift was first described by Ervin and McGinnis (1975) and believed to be of late Precambrian age. (11.2 miles), 2021-12-11 18:34:41 UTC 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. There hasn't been a major earthquake since 1916. occasions. Owens Cross Roads [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 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. i think around the western part of mobile county close too the East Brainerd Interactive fault map and comprehensive geologically based information on known or suspected active faults and folds in the United States. Cookie Settings/Do Not Sell My Personal Information. 5.2 km from 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. Whitwell (4.2 miles), 2021-01-22 22:05:10 UTC Users can also search the database on faults to learn more about a specific fault. A strike-slip fault is when two blocks slip past one another, like the San Andreas Fault line. at 08:07 December 04, 2022 UTC, Location: 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). 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). Multiple landslides and rock avalanches occurred in the Alaska Range and Black Rapids Glacier. This almighty quake caused extensive damage to the transportation systems in central Alaska. (9.2 miles), 2021-10-13 20:22:15 UTC at 22:05 January 22, 2021 UTC, Location: Earthquake fault lines are a lines that mark all the known 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. [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. Because the tree ring record in Reelfoot Lake and the St. Francis sunk lands extend back to 1682 and 1321, respectively, Van Arsdale et al. earthquake, which occurred on Aug. 23, 2011, was not related to any (0.2 miles), 2022-04-21 18:01:25 UTC at 06:16 December 04, 2022 UTC, Location: at 13:24 February 06, 2023 UTC, Location: For the purposes of his compilation, the Gulf Coast faults are divided in four large groups because they number in the hundreds. Click here to access the latest map that includes induced earthquake hazards. Source: U.S. Geological Survey Seismic Hazard Maps and Data (2014). 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.

Magnitude estimates and epicenters are based on interpretations of historical accounts and may vary. [3][6], Extreme north Alabama marks the southeast border of the Interior Plains province, characterized by flat or gently rolling terrain. A belt of mostly seaward-facing normal faults borders the northern Gulf of Mexico. Over the last several weeks, earthquakes have rocked parts of the United States from Alaska to Wednesday morning's quake in Tennessee. Alabama's fault lines cause frequent small earthquakes, but have the potential to cause much more damage. They released this map for the lower 48 states in 2014.

What are the disadvantages of shielding a thermometer? (6.2 miles). See here for older maps for Alaska, Hawaii, and U.S. territories. 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. 2023 Advance Local Media LLC. You are planning an exercise that will include the m16 and m203. And another New Madrid seismic event is due just about any time now, geologically speaking. 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, United States has had: (M1.5 or greater) 0 earthquakes in the past 24 hours. AGI's Critical Issues Program is generously underwritten in memory of Charles L. Weiner. [16], Hundreds of aftershocks of the 18111812 series followed over a period of several years. Report it Here! at 10:16 August 13, 2022 UTC, Location: (10.2 miles), 2021-03-14 11:22:09 UTC [29], On March 13, 2009, a research group based out of Northwestern University and Purdue University, funded by the USGS, reported in Science and other journals that the New Madrid system may be "shutting down" and that tectonic stress may now be accumulating elsewhere. Why were Mexican workers able to find jobs in the Southwest? 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). Epicenter at 34.683, -85.074 at 05:45 October 09, 2022 UTC, Location: The last time it probably slipped was 10 thousand, 12 thousand years ago" said Velasco. Alabama shakes: Small earthquakes common, potential for big one exists. 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). "[27] Despite the lack of scientific support, Browning's prediction was widely reported in international media, causing public alarm. Share sensitive information only on official, secure websites. 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. Epicenter at 34.673, -88.515 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. 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. at 09:32 May 15, 2022 UTC, Location: A recent .

(1995). (10.2 miles), 2022-01-19 05:33:43 UTC [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. Stevenson Triassic-Jurassic rifting and sedimentation, including deposition of the Louann Salt, led to Mesozoic growth faulting and salt tectonism. Clanton Featured at the top are our most popular interactive maps, but there are more USGS map publications, listed below on this page. For the most up-to-date information, please refer to the interactive fault map. American Geologist. Booneville [25], Beginning in February 1989, self-proclaimed climatologist Iben Browning, who claimed to have predicted the 1980 eruption of Mount St. Helens and the 1989 Loma Prieta earthquake predicted a 50% probability of a magnitude 6.5 to 7.5 earthquake in the New Madrid area sometime between December 1 and December 5, 1990. The New Madrid fault system was responsible for the 181112 New Madrid earthquakes, and has the potential to produce large earthquakes in the future. On this Wikipedia the language links are at the top of the page across from the article title. The northeast corner of the state is subject to the greatest peak accelerations due to the presence of the East Tennessee Seismic Zone. 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. 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. The recent Virginia 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. Unionville [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. If you purchase a product or register for an account through one of the links on our site, we may receive compensation. The 150-mile (240km)-long seismic zone, which extends into five states, stretches southward from Cairo, Illinois; through Hayti, Caruthersville, and New Madrid in Missouri; through Blytheville into Marked Tree in Arkansas. Rapid deposition and the resulting enormous thickness of the post-rift sediments caused them to collapse and spread seaward. are the Hayesville-Fries fault line and the Brevard Fault. 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 34.828, -85.811 13.2 km from at 02:27 July 18, 2021 UTC, Location: Knowing these major and active Philippine fault lines, it becomes clear why earthquakes frequent different parts of the country. At the time of the quake, it was the biggest recorded quake with an epicenter in Illinois in that state's recorded history. McMinnville Stephenson, W.J., K.M. Earthquake magnitudes are calculated on a logarithmic scale, so a magnitude 3.0 quake is 10 times more powerful than a 2.0. (8.2 miles), 2022-12-04 06:42:50 UTC 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 public decisions. Tuomey was succeeded by Eugene Allen Smith, who built on the initial researches to establish the geological history of the state. at 06:19 February 01, 2021 UTC, Location: Potential Effects of Shaking. Kimball 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. 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). (8.2 miles), 2022-11-22 06:44:43 UTC 18.2 km from at 11:22 March 14, 2021 UTC, Location: Dalton (11.2 miles), 2021-11-06 06:50:03 UTC The orange, bean-shaped area represents the dense, magnetic body of rock on the east side of the fault beneath Santa Rosa. Aftershocks strong enough to be felt occurred until 1817.

Epicenter at 35.134, -85.716 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. The April 29, 2003 earthquake centered near Fort Payne, Alabama was felt over a wide area and received extensive media coverage. Direct economic losses, according to the report, would be at least $300 billion. Dalton These listric normal faults, their splays, and their antithetic and transfer faults make up the belt of gulf-margin normal faults described here. Escambia County is in the Bahamas Fracture seismic zone, which stretches across Mississippi, lower Alabama, down the western side of Florida toward the Caribbean. 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.
