East Franklin Mountain Fault Courtesy of Dr. Jose Hurtado. Dalton 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 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. Report it Here! Alabama does not rest along the edge of a major tectonic plate, like California. 2.1 earthquake - 6.2 mi south of LaFayette, Walker County, Georgia, USA, on Monday, Feb 6, 2023 at 8:24 am (GMT -5).

And then you have little shifts and thats what ends up initiating your earthquakes.. On this Wikipedia the language links are at the top of the page across from the article title. This post-rift sequence thickens seaward (Salvador, 1991 #2020). Users can also search the database on faults to learn more about a specific fault. The quake damaged the civic building at Henderson, Kentucky, and was felt in 23 states. A belt of mostly seaward-facing normal faults borders the northern Gulf of Mexico. at 05:45 October 09, 2022 UTC, Location: 18.2 km from The northeast corner of the state is subject to the greatest peak accelerations due to the presence of the East Tennessee Seismic Zone.

Epicenter at 34.828, -85.811 The recent Virginia A fault line called the Pollard Fault System runs through the area of Escambia County, connecting with the Foshee Fault System in Florida. For the purposes of his compilation, the Gulf Coast faults are divided in four large groups because they number in the hundreds. For the most up-to-date information, please refer to the interactive fault map. Advanced National Seismic System Latest earthquakes map and list (past 24 hours, M2.5+). The strongest earthquake in state history, it registered an estimated Richter scale magnitude of 5.1 and resulted in extensive, but minor damage. (3.2 miles), 2021-04-07 06:37:11 UTC 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 11:22 March 14, 2021 UTC, Location: 2023-02-12 02:43:51 (UTC-08:00) 44.1 km . All rights reserved.

Share Settings Since then, more than 4,000 earthquakes have been recorded, most of which were too small to be felt. Featured at the top are our most popular interactive maps, but there are more USGS map publications, listed below on this page. Over the last several weeks, earthquakes have rocked parts of the United States from Alaska to Wednesday morning's quake in Tennessee. [28] This contrasts to the rate of slip on the San Andreas Fault, which averages up to 37mm (1.5in) a year across California. 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. The New Madrid fault system was responsible for the 181112 New Madrid earthquakes, and has the potential to produce large earthquakes in the future. Tuomey was succeeded by Eugene Allen Smith, who built on the initial researches to establish the geological history of the state.

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. There's one database for Class A and B faults and another for Class C and D faults. Dalton 3.2 km from The 3.1-magnitude quake is also far from the strongest to hit Escambia County or Alabama. Powells Crossroads 13.2 km from On March 6, a magnitude-2.6 earthquake was recorded near Century, Florida, close to the Alabama border. in the U.S. east of the Rocky Mountains. 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. 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. C/Yellow. Epicenter at 32.784, -86.766 at 06:19 March 30, 2022 UTC, Location: Epicenter at 35.636, -85.655 2654 Last Review Date: 1998-08-11 The post-rift sequence and its belt of gulf-margin normal faults may be mechanically decoupled from the underlying crust. [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. Epicenter at 34.66, -86.399 (8.2 miles), 2022-12-04 08:07:27 UTC AGI's Critical Issues Program is generously underwritten in memory of Charles L. Weiner. The epicenter of the quake was located at 18.44N., 72.57W.

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). [9] 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. The most recent quake registered as a magnitude 4.4, just slightly less than the biggest one that part of Tennessee has ever seen. [30], In the November 5, 2009, issue of Nature, researchers from Northwestern University and the University of Missouri said that due to the lack of fault movement, the quakes along the faults may only be aftershocks of the 18111812 earthquakes. 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. The period passed with no major earthquake activity in New Madrid or along the 120-mile (190km) fault line. Multiple landslides and rock avalanches occurred in the Alaska Range and Black Rapids Glacier. [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. "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 10:57 December 04, 2022 UTC, Location: Only List Earthquakes Shown on Map . 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. (4.2 miles), 2021-11-07 06:12:39 UTC A fault is a break in the earth's crust along which movement can take place causing an earthquake. [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. Join half a million readers enjoying Newsweek's free newsletters. 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. 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. National Earthquake Hazards Reduction Program (NEHRP). fault. The New Madrid fault system was responsible for the 1811-12 New Madrid earthquakes . Unionville These maps are used in determining building seismic codes, insurance rates, and other 5.2 km from [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 1916 Irondale earthquake struck in the north-central region of the U.S. state of Alabama on October 18. The estimated magnitude of this earthquake ranged from 7.0 to 7.9 with a surface wave magnitude of close to 8.5. 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. 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. Thorsby Epicenter at 34.673, -85.103 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. 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. [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. Epicenter at 35.296, -85.484 Booneville [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 the time of the quake, it was the biggest recorded quake with an epicenter in Illinois in that state's recorded history. We do have episodes of this kind of seismic activity clusters once in a while, Ebersole said. [14][15], A meteor crater over five miles in diameter was identified near Wetumpka, Alabama in 19691970. The GSA reported: "Near the epicenter, chimneys were knocked down, windows. 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. Epicenter at 32.874, -86.672 On average, one earthquake per year is large enough to be felt in the area. 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.
