Share Settings Epicenter at 34.66, -86.399 Users can also search the database on faults to learn more about a specific fault. [12] The Cahaba Basin and Black Warrior Basin in central Alabama produce coalbed methane. [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]. 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). Epicenter at 32.784, -86.766 at 20:22 October 13, 2021 UTC, Location: 82 km S of Manokwari, Indonesia. Dalton at 09:32 May 15, 2022 UTC, Location: at 17:09 August 21, 2022 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. Epicenter at 35.296, -85.484 The 1916 Irondale earthquake struck in the north-central region of the U.S. state of Alabama on October 18. [3] The Reelfoot Rift was first described by Ervin and McGinnis (1975) and believed to be of late Precambrian age. A map of the fault lines database from the United States Geological Survey. 4.5. Dalton A .gov website belongs to an official government organization in the United States. 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. These features were interpreted to have been caused by groups of large earthquakes timed closely together. There is one major fault line that runs through Alabama and the rest of the gulf coast. [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 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]. 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. The gulf-margin normal faults in Alabama and Florida are assigned as Class B structures because their low seismicity and because they may be decoupled from underlying crust, making it unclear if they can generate significant seismic ruptures that could cause damaging ground motion. "Thats normal seismic activity for our area.. 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). Epicenter at 34.683, -85.074 These were interpreted as clear signals of the 18111812 earthquake series in tree rings. The most recent quake registered as a magnitude 4.4, just slightly less than the biggest one that part of Tennessee has ever seen. A fault line called the Pollard Fault System runs through the area of Escambia County, connecting with the Foshee Fault System in Florida. Vol. 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). 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. [] Reply. National Earthquake Hazards Reduction Program (NEHRP). 5.2 km from 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. at 12:08 September 11, 2021 UTC, Location: Trion All rights reserved. Dalton This post-rift sequence thickens seaward (Salvador, 1991 #2020). Furthermore, some of the sparse seismicity in the normal-fault belt may be artificially induced. [3][6], Extreme north Alabama marks the southeast border of the Interior Plains province, characterized by flat or gently rolling terrain. 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. Accordingly, the fault belt is assigned to class B. Epicenter at 34.685, -85.078 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.

(1.2 miles), 2022-03-30 06:19:59 UTC [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. The Geological Survey of Alabama provides an online interactive map of earthquake information for Alabama. Secure .gov websites use HTTPS East Brainerd A belt of mostly seaward-facing normal faults borders the northern Gulf of Mexico in westernmost Florida, southwestern Alabama, southern Mississippi, all of Louisiana and southernmost Arkansas, and eastern and southern Texas (Ewing and Lopez, 1991 #2032). [16], Hundreds of aftershocks of the 18111812 series followed over a period of several years. Dalton Newest First. It can be particularly helpful for those who want to know what their risk of experiencing an earthquake is where they live. 10.2 km from Stevenson Sandy Ebersole, who heads the division of the Geological Survey of Alabama that documents and studies earthquakes in the state, said its not unusual or surprising to have multiple small-scale earthquakes in quick succession in the state. The orange, bean-shaped area represents the dense, magnetic body of rock on the east side of the fault beneath Santa Rosa. See here for older maps for Alaska, Hawaii, and U.S. territories. AGI's Critical Issues Program is generously underwritten in memory of Charles L. Weiner. Gulf-margin normal faults, Alabama and Florida (Class B) No. American Geologist. The strongest is a magnitude 4.7 that struck in 1973. 16.2 km from Seriously, check here first. Epicenter at 34.601, -85.479 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. i think around the western part of mobile county close too the The 3.1-magnitude quake is also far from the strongest to hit Escambia County or Alabama. (3.2 miles), 2022-08-21 17:09:31 UTC However, geologists are concerned with 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. Aftershocks strong enough to be felt occurred until 1817. Bookmark this page to return to map/list with the same settings or save your settings with the button below.

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. [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. Triassic-Jurassic rifting and sedimentation, including deposition of the Louann Salt, led to Mesozoic growth faulting and salt tectonism. 2023 Advance Local Media LLC. 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. Lakesite Advanced National Seismic System Latest earthquakes map and list (past 24 hours, M2.5+). 2.1 earthquake - 6.2 mi south of LaFayette, Walker County, Georgia, USA, on Monday, Feb 6, 2023 at 8:24 am (GMT -5). How did you use the result to determine who walked fastest and slowest? And then you have little shifts and thats what ends up initiating your earthquakes.. However, there are several intraplate faults running through the state that can cause frequent small earthquakes, and rare larger ones. Epicenter at 32.957, -88.046 [27], The lack of apparent land movement along the New Madrid fault system has long puzzled scientists. Earthquake magnitudes are calculated on a logarithmic scale, so a magnitude 3.0 quake is 10 times more powerful than a 2.0. The equipment recorded more than 200 earthquakes during that time, ranging from M 0.8 to M 4. 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. 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? line that runs from New York to Alabama. Alabama's fault lines cause frequent small earthquakes, but have the potential to cause much more damage. [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. What are the two applications of bifilar suspension? Earthquake fault lines are a lines that mark all the known What are the disadvantages of shielding a thermometer?

The fault runs along the east side of the Franklins. Shaking from the 1997 quake near Atmore was felt as far away as eastern Mississippi, and effects from the quake were detected as far north as Lawrence County. [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. There's one database for Class A and B faults and another for Class C and D faults. 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. Knowing these major and active Philippine fault lines, it becomes clear why earthquakes frequent different parts of the country. Copyright 2023. Stephenson, W.J., K.M. The largest quake to strike Alabama directly was a 5.1 magnitude that hit the Irondale-Easonville area on Oct. 18, 1916. Post, This map illustrates 119 years of global seismicity in the context of global plate tectonics and the Earths physiography. 14.2 km from (July 17, 2014), "Center for Earthquake Research and Information at the University of Memphis", "Reelfoot rift and its impact on Quaternary deformation in the central Mississippi River valley", "Reelfoot Rift: Reactivated Precursor to the Mississippi Embayment", 10.1130/0016-7606(1975)86<1287:RRRPTT>2.0.CO;2, "Uncovering Hidden Hazards in the Mississippi Valley", "USGS Earthquake Hazards Program, Earthquake Report: Kentucky", 10.1130/0091-7613(2001)029<0175:DDTISI>2.0.CO;2, "Sinking Mafic Body in a Reactivated Lower Crust: A Mechanism for Stress Concentration at the New Madrid Seismic Zone", "Descent of the ancient Farallon slab drives localized mantle flow below the New Madrid seismic zone", "How old is the New Madrid Seismic Zone? Trion 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. Tuomey was succeeded by Eugene Allen Smith, who built on the initial researches to establish the geological history of the state. At 1 pm on Christmas Day 1699, at a site near the present-day location of Memphis, the party was startled by a short period of ground shaking. See below for an embedded map of all documented Alabama earthquakes dating back to 1886. What is the Denouement of the story a day in the country? are the Hayesville-Fries fault line and the Brevard Fault.

In Alabama, this province generally lies north of the Tennessee River. 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. 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 34.579, -85.892 This fault line is called the Quaternary at 08:07 December 04, 2022 UTC, Location: Hazel Green Epicenter at 34.673, -88.515 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. (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).
