(7.2 miles), 2021-12-22 06:20:48 UTC See the Related Link below for more information on fault lines 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. The equipment recorded more than 200 earthquakes during that time, ranging from M 0.8 to M 4. earthquake, which occurred on Aug. 23, 2011, was not related to any Booneville [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. Epicenter at 35.296, -85.484 The fault runs along the east side of the Franklins. [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. Aftershocks strong enough to be felt occurred until 1817. 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 estimated magnitude of this earthquake ranged from 7.0 to 7.9 with a surface wave magnitude of close to 8.5. Epicenter at 34.684, -85.073 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. 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. Epicenter at 32.874, -86.672 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. 2023-02-12 02:43:51 (UTC-08:00) 44.1 km . (8.2 miles), 2022-12-04 06:42:50 UTC 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. (3.2 miles), 2021-02-01 06:19:25 UTC Epicenter at 35.169, -85.104 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. Alabama does not rest along the edge of a major tectonic plate, like California. 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. A lock () or https:// means youve safely connected to the .gov website. The Geological Survey of Alabama provides an online interactive map of earthquake information for Alabama. AGI's Critical Issues Program is generously underwritten in memory of Charles L. Weiner. The post-rift sequence as a whole is at least 9-11 km thick throughout the Coastal zone (Salvador, 1991 #2020). Epicenter at 34.98, -86.619 (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). According to the U.S. Geological Surveys self-reporting tool, the 3.1-magnitude quake was detected as far away as Mobile and Pensacola. [3] The Reelfoot Rift was first described by Ervin and McGinnis (1975) and believed to be of late Precambrian age. View Earthquake Map Faults Interactive fault map and comprehensive geologically based information on known or suspected active faults and folds in the United States. Epicenter at 35.636, -85.655 at 12:08 September 11, 2021 UTC, Location: [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. at 05:33 January 19, 2022 UTC, Location: Monday afternoon, a magnitude-3.1 quake hit northeast of Flomaton. In 2009, two studies based on eight years of GPS measurements indicated that the faults were moving at no more than 0.2 mm (0.008 in.) 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. Faults with evidence of Holocene (about 10,000 . 16.2 km from Seriously, check here first. The epicenter of the quake was located at 18.44N., 72.57W. 9.2 km from [12] The Cahaba Basin and Black Warrior Basin in central Alabama produce coalbed methane. at 06:19 March 30, 2022 UTC, Location: A fault is a break in the earth's crust along which movement can take place causing an earthquake. GIS shapefiles and metadata: Geospatial Hazards Data page. Triassic-Jurassic rifting and sedimentation, including deposition of the Louann Salt, led to Mesozoic growth faulting and salt tectonism. Epicenter at 34.598, -85.456 Only List Earthquakes Shown on Map . Secure .gov websites use HTTPS Subscribe to Earthquake Notifications ShakeAlert Earthquake Early Warning Significant Earthquakes, Past 30 Days Significant Earthquakes Archive California Department of Conservation. Epicenter maps show only sparse, low-magnitude seismicity within the fault belt (Engdahl, 1988 #1959; Stover and Coffman, 1993 #1986). Tuomey was succeeded by Eugene Allen Smith, who built on the initial researches to establish the geological history of the state. These maps are used in determining building seismic codes, insurance rates, and other public decisions. 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. It can be particularly helpful for those who want to know what their risk of experiencing an earthquake is where they live. They released this map for the lower 48 states in 2014. (3.2 miles), 2022-08-21 17:09:31 UTC 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. 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. Due to the fault, the blocks can easily move, which is what is happening when an earthquake occurs. American Geosciences Institute. Epicenter at 34.802, -85.046 reason i say this , is because the other night on Epicenter at 35.556, -86.55 Post, This map illustrates 119 years of global seismicity in the context of global plate tectonics and the Earths physiography. 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. Interactive fault map and comprehensive geologically based information on known or suspected active faults and folds in the United States. [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. There hasn't been a major earthquake since. 13.2 km from Epicenter at 35.226, -85.073 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. There is one major fault line that runs through Alabama and the rest of the gulf coast. The two biggest fault lines that run through North Carolina Join half a million readers enjoying Newsweek's free newsletters. That quake was the second largest ever recorded in Alabama, behind an estimated magnitude-5.2 quake that hit northern Shelby County in 1916. However, geologists are concerned with are the Hayesville-Fries fault line and the Brevard Fault. The USGS and its partners monitor and report earthquakes, assess earthquake impacts and hazards, and perform research into the causes and effects of earthquakes. Here a map of the major earthquake fault lines in the USA. There is one major fault line that runs through Alabama and the #1806 Chang, T.M., Ammon, C.J., and Herrmann, R.B., 1998, Faulting parameters of the October 24, 1997 southern Alabama earthquake [abs. at 06:20 December 22, 2021 UTC, Location: [16], Hundreds of aftershocks of the 18111812 series followed over a period of several years. Alabama spans three continental geologic provinces as defined by the United States Geological Survey, the Atlantic Plain, Appalachian Highlands, and Interior Plains. In 1997, the a magnitude-4.9 earthquake was recorded northeast of Atmore. Trion earthquakes in an area or region. [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]. [9] Since 1886, slightly more than 10 percent of earthquakes with an epicenter in Alabama have been an estimated magnitude 3 or greater. "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. (6.2 miles). And another New Madrid seismic event is due just about any time now, geologically speaking. 16.2 km from All rights reserved.

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. Official websites use .gov Epicenter at 34.859, -85.547 4.2 km from Clanton 2.2 km from 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). Dalton The orange, bean-shaped area represents the dense, magnetic body of rock on the east side of the fault beneath Santa Rosa. Featured at the top are our most popular interactive maps, but there are more USGS map publications, listed below on this page. 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. What is A person who sells flower is called? This fault line is called the Quaternary fault. Format. 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. 10.2 km from Dalton at 08:07 December 04, 2022 UTC, Location: It is southwest of the Wabash Valley Seismic Zone. Aliceville Epicenter at 33.201, -86.11 at 10:57 December 04, 2022 UTC, Location: fault. A fault line called the Pollard Fault System runs through the area of Escambia County, connecting with the Foshee Fault System in Florida. Known surface faults and interpreted subsurface faults are also shown, allowing users to see the relationships between different identified faults and historical earthquakes. C/Yellow. (6.2 miles), 2022-09-04 21:51:08 UTC 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. Epicenter at 35.046, -85.128 The largest quake to strike Alabama directly was a 5.1 magnitude that hit the Irondale-Easonville area on Oct. 18, 1916. Note that most faults that can affect residents are either onshore or just offshore. 9.2 km from [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.
