[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. 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. On Wednesday, a 2.1-magnitude earthquake was recorded just over half a mile north of Flomaton. rest of the gulf coast. 2023-02-24 07:37:18 UTC 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? The USGS and its partners monitor and report earthquakes, assess earthquake impacts and hazards, and perform research into the causes and effects of earthquakes. 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. The last time it probably slipped was 10 thousand, 12 thousand years ago" said Velasco. 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. YouTubes privacy policy is available here and YouTubes terms of service is available here. 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. The 3.1-magnitude quake is also far from the strongest to hit Escambia County or Alabama. (8.2 miles), 2022-12-04 08:07:27 UTC LaFayette Seriously, check here first. [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. 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). [14][15], A meteor crater over five miles in diameter was identified near Wetumpka, Alabama in 19691970. For the most up-to-date information, please refer to the interactive fault map. "And from what they've been able to determine is that these events occur on an average cycle of 200-300 years.". Over the last several weeks, earthquakes have rocked parts of the United States from Alaska to Wednesday morning's quake in Tennessee. D/Light Brown. 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 New York-Alabama Lineament, which is a major magnetic fault Smith, Eugene Allen (October 1897) "Sketch of the Life of Michael Tuomey". It is at least 2 km thick everywhere in the belt of gulf-margin normal faults. (8.2 miles), 2022-12-04 06:16:37 UTC 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 period passed with no major earthquake activity in New Madrid or along the 120-mile (190km) fault line.

Due to the fault, the blocks can easily move, which is what is happening when an earthquake occurs. The most recent quake registered as a magnitude 4.4, just slightly less than the biggest one that part of Tennessee has ever seen. The epicenter of the quake was located at 18.44N., 72.57W. Owens Cross Roads 10.2 km from 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. 2023 Advance Local Media LLC. Dalton at 06:37 April 07, 2021 UTC, Location: The New Madrid fault system was responsible for the 1811-12 New Madrid earthquakes . occasions. [27], The lack of apparent land movement along the New Madrid fault system has long puzzled scientists. The New Madrid fault system was responsible for the 181112 New Madrid earthquakes, and has the potential to produce large earthquakes in the future. 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).

[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. 13.2 km from [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. 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. Epicenter at 34.708, -85.285 There is one major fault line that runs through Alabama and the 0.2 km from The 3.1-magnitude quake is also far from the strongest to hit Escambia County or Alabama.

[4] The rift failed to split the North American continent, but it has remained as an aulacogen (a scar or zone of weakness) deep underground. Earthquakes occur nearly every day in Washington. 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. (3.2 miles), 2022-12-04 10:57:58 UTC Most of the seismicity originates between 3 and 15 miles (4.8 and 24.1km) beneath the Earth's surface. The largest quake to strike Alabama directly was a 5.1 magnitude that hit the Irondale-Easonville area on Oct. 18, 1916. All rights reserved. are the Hayesville-Fries fault line and the Brevard Fault. Magnitude estimates and epicenters are based on interpretations of historical accounts and may vary. 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. Strong shakingDamage negligible in buildings of good design and construction; slight to moderate in well-built ordinary structures; considerable damage in poorly built structures.

Triassic-Jurassic rifting and sedimentation, including deposition of the Louann Salt, led to Mesozoic growth faulting and salt tectonism. The data behind it was acquired in the early hours of Friday by the European Union's Sentinel-1A satellite as it traversed north to south over Turkey at an altitude of 700km (435 miles). Vol. [32], In July 2014, the USGS increased the risk assessment for the New Madrid area. 2 earthquakes in the past 30 days. Thicknesses exceed 12 km under coastal Texas and southern Louisiana and perhaps 16 km offshore Louisiana. (7.2 miles), 2021-12-22 06:20:48 UTC 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. 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. [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.

(2.2 miles), 2021-08-25 06:19:18 UTC 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. 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. Fault lines are really located everywhere, but it's usually the Tap/click on "gear icon" for options and settings. 5.2 km from Here a map of the major earthquake fault lines in the USA. 9.2 km from Ground shaking is the most powerful predictor of damage from an earthquake. Epicenter at 34.683, -85.074 Our motivation for studying the Bear River Fault Zonea nascent normal fault in the Rocky Mountains east of the Basin and Range physiographic provinceis twofold: (1) the intriguing conclusion from previous work that, The accompanying map and digital data identify recently active strands of the Rodgers Creek Fault in Sonoma County, California, interpreted primarily from the geomorphic expression of recent faulting on aerial photography and hillshade imagery derived from airborne lidar data. A fault line called the Pollard Fault System runs through the area of Escambia County, connecting with the Foshee Fault System in Florida. The American Geosciences Institute represents and serves the geoscience community by providing collaborative leadership and information to connect Earth, science, and people. [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. (8.2 miles), 2022-10-09 05:45:39 UTC Epicenter at 33.201, -86.11 At the time of the quake, it was the biggest recorded quake with an epicenter in Illinois in that state's recorded history. Epicenter at 35.556, -86.55 Because numerous individual faults are combined into a single group for this compilation, it is not possible to provide to provide digital information about the azimuth, length, and dip of each individual fault. Epicenter at 35.134, -85.716 [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. 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). 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. [9] Since 1886, slightly more than 10 percent of earthquakes with an epicenter in Alabama have been an estimated magnitude 3 or greater. [28] Seth Stein, the leader of the research group, published these views in a book, Disaster Deferred, in 2008. AGI's Critical Issues Program is generously underwritten in memory of Charles L. Weiner. 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. Three quakes so close together might qualify as unusual, but its hardly unprecedented. A fault is a fracture between two blocks of rock, according to the United States Geological Survey. Maps of these fault lines can be [citation needed], The faults responsible for the NMSZ are embedded in a subsurface geological feature known as the Reelfoot Rift, which likely formed during the Cambrian Period. 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. There is one major fault line that runs through Alabama and the rest of the gulf coast. [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] 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.
