The stress field is extensional throughout the post-rift sequence in both the Interior and Coastal zones of the normal-fault belt, as determined mostly from drill-hole data that demonstrate fault slips and well-bore breakouts (Zoback and Zoback, 1991 #2006). Trion UK NEWS: FIND OUT IF THERE ARE TRAIN STRIKES IN MARCH 2023 . 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. Sylvania 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). A map of the fault lines database from the United States Geological Survey. 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 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. This post-rift sequence thickens seaward (Salvador, 1991 #2020). 11.2 km from Why were Mexican workers able to find jobs in the Southwest? Epicenter at 34.615, -85.29 [26][27] Browning appears to have based this prediction on particularly strong tidal forces being expected during that time, and his opinion that a New Madrid earthquake was "overdue;" however, seismologists generally agree that no correlation exists between tides and earthquakes. American Geologist. Direct economic losses, according to the report, would be at least $300 billion. 2.1 earthquake - 6.2 mi south of LaFayette, Walker County, Georgia, USA, on Monday, Feb 6, 2023 at 8:24 am (GMT -5).

Due to the fault, the blocks can easily move, which is what is happening when an earthquake occurs. Instruments were installed in and around the area in 1974 to closely monitor seismic activity. 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. at 21:51 September 04, 2022 UTC, Location: There is one major fault line that runs through Alabama and the [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. A fault is a fracture between two blocks of rock, according to the United States Geological Survey. at a depth of 13 kilometers (km) approximately 25 km southwest of the capital, Port-au-Prince. One concern is that the small earthquakes that still happen are not diminishing over time, as would be if they were aftershocks of the 18111812 events; another is that the 4,500-year archaeological record of large earthquakes in the region is more significant than 10 years of direct strain measurement. (1995). [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. Epicenter at 35.296, -85.484 For the most up-to-date information, please refer to the interactive fault map. [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. what type of danger zone is needed for this exercise. However, geologists are concerned with 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). Epicenter at 34.764, -84.942 Kimball [29], On March 13, 2009, a research group based out of Northwestern University and Purdue University, funded by the USGS, reported in Science and other journals that the New Madrid system may be "shutting down" and that tectonic stress may now be accumulating elsewhere. 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. 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. Thorsby And another New Madrid seismic event is due just about any time now, geologically speaking. 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. at 18:34 December 11, 2021 UTC, Location: Dalton 13.2 km from This map shows areas of seismic risk from high (red) to low (grayish-green). [27], The lack of apparent land movement along the New Madrid fault system has long puzzled scientists. Copyright 2023. Post, This map illustrates 119 years of global seismicity in the context of global plate tectonics and the Earths physiography. Ground shaking is the most powerful predictor of damage from an earthquake. 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). [11], Alabama's abundant natural mineral resources include commercially viable deposits of coal, oil, natural gas, and various minerals such as limestone and marble. 5.2 km from Share sensitive information only on official, secure websites. 2023 Advance Local Media LLC. [1][2] The Geological Survey of Alabama breaks these provinces down into more specific physiographic provinces. The 1895 event had its epicenter near Charleston, Missouri. Vol. [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]. The fault runs along the east side of the Franklins. Earthquake magnitudes are calculated on a logarithmic scale, so a magnitude 3.0 quake is 10 times more powerful than a 2.0. at 05:33 January 19, 2022 UTC, Location: Unionville 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. at 06:12 November 07, 2021 UTC, Location: 16.2 km from The. 8.2 km from The 1916 Irondale earthquake struck in the north-central region of the U.S. state of Alabama on October 18.

Epicenter at 32.874, -86.672 The 3.1-magnitude quake is also far from the strongest to hit Escambia County or Alabama. What are the disadvantages of shielding a thermometer? Monday afternoon, a magnitude-3.1 quake hit northeast of Flomaton. Conclusive evidence of the origin of the Wetumpka Impact Crater was found by Auburn University geology professor David T. King in 1998.[16]. A fault is a break in the earth's crust along which movement can take place causing an earthquake. For the purposes of his compilation, the Gulf Coast faults are divided in four large groups because they number in the hundreds. Salt flowed southward and pierced upward, and the overlying sediments extended on listric, normal, growth faults that flatten downward into detachments in the salt and in overpressured shales (Ewing, 1991 #1994; Nelson, 1991 #1995).

The post-rift sequence and its belt of gulf-margin normal faults may be mechanically decoupled from the underlying crust. Click here to access the interactive earthquake map of Alabama. [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. 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. 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). fault. Earthquake Hazard in the New Madrid Seismic Zone Remains a Concern USGS (2009). Dalton 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 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.
