These maps are used in determining building seismic codes, insurance rates, and other It is at least 2 km thick everywhere in the belt of gulf-margin normal faults. 10.2 km from SDC/Map Color. The quake damaged the civic building at Henderson, Kentucky, and was felt in 23 states. 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. At the time of the quake, it was the biggest recorded quake with an epicenter in Illinois in that state's recorded history. The April 29, 2003 earthquake centered near Fort Payne, Alabama was felt over a wide area and received extensive media coverage. at 06:16 December 04, 2022 UTC, Location: Magnitude. At the coastline, the sequence is at least 10 km thick west of the Mississippi River and at least 5 km thick farther east. People in Boston said their buildings swayed. Direct economic losses, according to the report, would be at least $300 billion. a Thursday we felt a tremor that shook the place, no one else knew Did You Feel It? Subscribe to Earthquake Notifications ShakeAlert Earthquake Early Warning Significant Earthquakes, Past 30 Days Significant Earthquakes Archive at 18:01 April 21, 2022 UTC, Location: Dalton 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). Earthquake scenarios describe the expected ground motions and effects of specific hypothetical large earthquakes. 14.2 km from 9.2 km from Extensive oil and gas deposits have been developed in the southern portion of the state, Mobile Bay, and coastal state waters. #1806 Chang, T.M., Ammon, C.J., and Herrmann, R.B., 1998, Faulting parameters of the October 24, 1997 southern Alabama earthquake [abs. at 10:16 August 13, 2022 UTC, Location: 1 earthquake in the past 7 days. Epicenter at 34.683, -85.074 Escambia County is in the Bahamas Fracture seismic zone, which stretches across Mississippi, lower Alabama, down the western side of Florida toward the Caribbean. A fault is a fracture between two blocks of rock, according to the United States Geological Survey. The American Geosciences Institute represents and serves the geoscience community by providing collaborative leadership and information to connect Earth, science, and people. 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. 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. Copyright 2023. [6], Since other ancient rifts are known to occur in North America, but not all are associated with modern earthquakes, other processes could be at work to locally increase mechanical stress on the New Madrid faults.

Accordingly, the fault belt is assigned to class B. 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. The fault runs along the east side of the Franklins. (2.2 miles), 2021-08-25 06:19:18 UTC East Franklin Mountain Fault Courtesy of Dr. Jose Hurtado. A normal fault is a type of dip-slip fault where one block moves down, a thrust fault is when the block moves up and over the one below it. [11] Archaeological studies have found from studies of sand blows and soil horizons that previous series of very large earthquakes have occurred in the NMSZ in recent prehistory. This page was last edited on 30 January 2023, at 06:41. Alabama spans three continental geologic provinces as defined by the United States Geological Survey, the Atlantic Plain, Appalachian Highlands, and Interior Plains. 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]. Gulf-margin normal faults, Alabama and Florida (Class B) No. [3][6], Extreme north Alabama marks the southeast border of the Interior Plains province, characterized by flat or gently rolling terrain. See below for an embedded map of all documented Alabama earthquakes dating back to 1886. [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 22:05 January 22, 2021 UTC, Location: (1.2 miles), 2022-03-30 06:19:59 UTC "There's a record going back several thousands of years in the geology of the area, and the floodplains of the Mississippi River that have recorded repeating large-magnitude earthquakes in the New Madrid seismic zone," Ebersole said. at 07:37 February 24, 2023 UTC, Location: How did you use the result to determine who walked fastest and slowest? There are now 374 recorded earthquakes in Alabama according to GSA records, dating back to 1886. 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. (3.2 miles), 2022-05-15 09:32:06 UTC Consistent with the stress field in the post-rift sequence, the normal-faulting focal mechanism of the 1997, M 4.9 earthquake in southwestern Alabama indicated south-southwest extension (Chang and others, 1998 #1806). 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). In Utah, movement along faults is mostly vertical; mountain blocks (for example, the Wasatch Range) move up relative to the downward movement of valley blocks (for example, the Salt Lake Valley). Click here to access the interactive earthquake map of Alabama. Dalton the New York-Alabama Lineament, which is a major magnetic fault In 1997, the a magnitude-4.9 earthquake was recorded northeast of Atmore. 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. Epicenter at 34.98, -86.619 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.

The report estimated 86,000 casualties, including 3,500 fatalities, 715,000 damaged buildings, and 7.2 million people displaced, with two million of those seeking shelter, primarily due to the lack of utility services. [11], Alabama's abundant natural mineral resources include commercially viable deposits of coal, oil, natural gas, and various minerals such as limestone and marble. Alabama shakes: Small earthquakes common, potential for big one exists. The Geological Survey of Alabama provides an online interactive map of earthquake information for Alabama. at 18:34 December 11, 2021 UTC, Location: [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. rest of the gulf coast. line that runs from New York to Alabama. [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. These were interpreted as clear signals of the 18111812 earthquake series in tree rings. Vol. The estimated magnitude of this earthquake ranged from 7.0 to 7.9 with a surface wave magnitude of close to 8.5. Epicenter at 35.296, -85.484 at 06:19 August 25, 2021 UTC, Location: There hasn't been a major earthquake since 1916. (0.2 miles), 2022-04-21 18:01:25 UTC 2023-02-12 02:43:51 (UTC-08:00) 44.1 km .

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. Magnitude estimates and epicenters are based on interpretations of historical accounts and may vary. [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. Maps of these fault lines can be 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. The recent Virginia Epicenter at 34.673, -85.103 In Alabama, this province generally lies north of the Tennessee River. Source: U.S. Geological Survey Seismic Hazard Maps and Data (2014). However, there are several intraplate faults running through the state that can cause frequent small earthquakes, and rare larger ones.

The interactive map to below shows epicenters of historical Alabama earthquakes since 1886 and surface and basement faults. To read more information on individual earthquakes or faults, click the feature on the map. There hasn't been a major earthquake since. Dalton Epicenter maps show only sparse, low-magnitude seismicity within the fault belt (Engdahl, 1988 #1959; Stover and Coffman, 1993 #1986). Instruments were installed in and around the area in 1974 to closely monitor seismic activity. ]: Seismological Research Letters, v. 69, p. 175-176. Here a map of the major earthquake fault lines in the USA. 14.2 km from Who makes the plaid blue coat Jesse stone wears in Sea Change? 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. 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. Sylvania An official website of the United States government. California Geological Survey. 5.2 km from Epicenter at 34.684, -85.073 in the U.S. east of the Rocky Mountains. 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. 18.2 km from Tap/click on "gear icon" for options and settings. A strike-slip fault is when two blocks slip past one another, like the San Andreas Fault line. The USGS Earthquake Hazards Program is part of the National Earthquake Hazards Reduction Program (NEHRP), established by Congress in 1977, and the USGS Advanced National Seismic System (ANSS) was established by Congress as a NEHRP facility. The map provides the locations, dates, and magnitudes of historical earthquakes, as well as highlighting recent earthquakes. They released this map for the lower 48 states in 2014. Three quakes so close together might qualify as unusual, but its hardly unprecedented. Multiple landslides and rock avalanches occurred in the Alaska Range and Black Rapids Glacier. Thicknesses exceed 12 km under coastal Texas and southern Louisiana and perhaps 16 km offshore Louisiana. 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. Advanced National Seismic System Latest earthquakes map and list (past 24 hours, M2.5+). (3.2 miles), 2021-04-07 06:37:11 UTC 16.2 km from at 06:12 November 07, 2021 UTC, Location: Where are the Alabama earthquake fault lines? 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). at 22:49 December 24, 2022 UTC, Location: 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. You are planning an exercise that will include the m16 and m203. (11.2 miles), 2021-11-06 06:50:03 UTC What are the two applications of bifilar suspension? (11.2 miles), 2021-12-11 18:34:41 UTC [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. See the Related Link below for more information on fault lines 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. However, geologists are concerned with at 06:37 April 07, 2021 UTC, Location: 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. Trion USGS scientists update these maps as they get more data and their knowledge about earthquake hazards improves. There are major and minor fault lines all over the United 3.2 km from 4.2 km from The fault could trigger the "Big One" and be followed by a tsunami, according to PHIVOLCS. Epicenter at 32.957, -88.046 reason i say this , is because the other night on Thorsby (7.2 miles), 2021-12-22 06:20:48 UTC The strongest earthquake in state history, it registered an estimated Richter scale magnitude of 5.1 and resulted in extensive, but minor damage. Join half a million readers enjoying Newsweek's free newsletters. 13.2 km from Alabama does not rest along the edge of a major tectonic plate, like California. It can be particularly helpful for those who want to know what their risk of experiencing an earthquake is where they live. The USGS and its partners monitor and report earthquakes, assess earthquake impacts and hazards, and perform research into the causes and effects of earthquakes. 4.5. [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. "Documentation for the 2014 Update of the United States National Seismic Hazard Maps", Earthquake Hazard in the New Madrid Seismic Zone Remains a Concern, U. 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. [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. "A fault that could potentially slip in modern times. Lidar imagery of the Wenas Valley illuminated the west-northwest-trending, 2- to 8-meter-high scarp as it bisected alluvial fans developed at the mouths of canyons along the south side of Umtanum Ridge. And then you have little shifts and thats what ends up initiating your earthquakes.. The period passed with no major earthquake activity in New Madrid or along the 120-mile (190km) fault line. 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). Note that most faults that can affect residents are either onshore or just offshore. 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 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. A 4.0 quake is 100 times more powerful than a 2.0 and so on. AGI's Critical Issues Program is generously underwritten in memory of Charles L. Weiner. Earthquake magnitudes are calculated on a logarithmic scale, so a magnitude 3.0 quake is 10 times more powerful than a 2.0. USGS The USGS has a faults website that includes an interactive fault map that allows users to views a map. occasions. 7.2 km from 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). The movement of the blocks makes the ground shift and shake. at 02:27 July 18, 2021 UTC, Location: FAQ - Frequently Asked Questions 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? 13.2 km from For the purposes of his compilation, the Gulf Coast faults are divided in four large groups because they number in the hundreds. Faults with evidence of Holocene (about 10,000 . 10.2 km from That quake was the second largest ever recorded in Alabama, behind an estimated magnitude-5.2 quake that hit northern Shelby County in 1916. 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. [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. [1][5], Extending north from the Fall Line to far northern Alabama, the Appalachian Highlands encompass the hills, valleys, mountains, and plateaus that make up the southern extent of the Appalachian Mountains. The zone had four of the largest earthquakes in recorded North American history, with moment magnitudes estimated to be as large as 7.0 or greater, all occurring within a 3-month period between December 1811 and February 1812. 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. The New Madrid fault system was responsible for the 181112 New Madrid earthquakes, and has the potential to produce large earthquakes in the future. "Thats normal seismic activity for our area.. Fault lines are really located everywhere, but it's usually the The post-rift sequence and its belt of gulf-margin normal faults may be mechanically decoupled from the underlying crust. fault. (3.2 miles), 2022-08-13 00:51:51 UTC Shedlock, and J.K. Odum. Post, This map illustrates 119 years of global seismicity in the context of global plate tectonics and the Earths physiography. The 3.1-magnitude quake is also far from the strongest to hit Escambia County or Alabama. All rights reserved. 4.2 km from Epicenter at 34.66, -86.399 All information managed by the Geological Survey of Alabama. 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). The last time it probably slipped was 10 thousand, 12 thousand years ago" said Velasco. [3] The Reelfoot Rift was first described by Ervin and McGinnis (1975) and believed to be of late Precambrian age. In October 2009, a team composed of University of Illinois and Virginia Tech researchers headed by Amr S. Elnashai, funded by the Federal Emergency Management Agency, considered a scenario where all three segments of the New Madrid fault ruptured simultaneously with a total earthquake magnitude of 7.7. Clicking on each dot will display additional information about the quake. 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. 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. These listric normal faults, their splays, and their antithetic and transfer faults make up the belt of gulf-margin normal faults described here. are the Hayesville-Fries fault line and the Brevard Fault.
