According to the U.S. Geological Surveys self-reporting tool, the 3.1-magnitude quake was detected as far away as Mobile and Pensacola. American Geologist. 9.2 km from Copyright 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. (3.2 miles), 2022-08-13 00:51:51 UTC Knowing these major and active Philippine fault lines, it becomes clear why earthquakes frequent different parts of the country. Epicenter at 34.685, -85.078 [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. [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. 4.2. . Epicenter at 35.169, -85.44 at 10:16 August 13, 2022 UTC, Location: [28] Seth Stein, the leader of the research group, published these views in a book, Disaster Deferred, in 2008. a Thursday we felt a tremor that shook the place, no one else knew American Geosciences Institute. (3.2 miles), 2021-02-01 06:19:25 UTC What is the Denouement of the story a day in the country? Who makes the plaid blue coat Jesse stone wears in Sea Change? 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. Lidar data acquired from the U.S. Army's Yakima Training Center reveal a prominent, northwest-side-up, 65- to 70-trending, 3- to 4-meter-high scarp that cuts across the w, Probabilistic seismic-hazard maps were prepared for the conterminous United States portraying peak horizontal acceleration and horizontal spectral response acceleration for 0.2- and 1.0-second periods with probabilities of exceedance of 10 percent in 50 years and 2 percent in 50 years. at 08:07 December 04, 2022 UTC, Location: 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. at 05:45 October 09, 2022 UTC, Location: There is one major fault line that runs through Alabama and the rest of the gulf coast. [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. GIS shapefiles and metadata: Geospatial Hazards Data page. 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. The estimated magnitude of this earthquake ranged from 7.0 to 7.9 with a surface wave magnitude of close to 8.5. at 18:01 April 21, 2022 UTC, Location: The American Geosciences Institute represents and serves the geoscience community by providing collaborative leadership and information to connect Earth, science, and people. 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. Alabama's fault lines cause frequent small earthquakes, but have the potential to cause much more damage. 2023 Advance Local Media LLC. (5.2 miles), 2021-08-21 12:50:14 UTC 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). In Alabama, this province generally lies north of the Tennessee River. Most of the seismicity originates between 3 and 15 miles (4.8 and 24.1km) beneath the Earth's surface. at 06:50 November 06, 2021 UTC, Location: Map showing recorded earthquakes in Alabama and the seismic zones that cause them. All rights reserved. Epicenter at 35.134, -85.716 For the purposes of his compilation, the Gulf Coast faults are divided in four large groups because they number in the hundreds. (7.2 miles), 2021-12-22 06:20:48 UTC Epicenter at 34.687, -85.077 at 17:09 August 21, 2022 UTC, Location: Earthquake magnitudes are calculated on a logarithmic scale, so a magnitude 3.0 quake is 10 times more powerful than a 2.0. Trion [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. Dalton Magnitude. 11.2 km from The period passed with no major earthquake activity in New Madrid or along the 120-mile (190km) fault line. [9] Since 1886, slightly more than 10 percent of earthquakes with an epicenter in Alabama have been an estimated magnitude 3 or greater. It also covers a part of West Tennessee, near Reelfoot Lake, extending southeast into Dyersburg. 13.2 km from For information about specific risks in your local area, contact your state geological survey or regional earthquake consortium: Click here to access the National Seismic Hazard maps. Note that most faults that can affect residents are either onshore or just offshore. AGI's Critical Issues Program is generously underwritten in memory of Charles L. Weiner. [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. Direct economic losses, according to the report, would be at least $300 billion. Everyone Practices Cancel Culture | Opinion, Deplatforming Free Speech is Dangerous | Opinion, 4.4 Magnitude Earthquake Rumbled Tennessee, Says USGS, East Antartica Glaciers Melting at 'Systematic' Rate. 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 3.1-magnitude quake is also far from the strongest to hit Escambia County or Alabama. What is A person who sells flower is called? (1995). Unionville Tap/click on "gear icon" for options and settings. Shedlock, and J.K. Odum. All of the maps were prepared by combining the hazard derived from spatially smoothed historic seismicity with th, The Dubakella Mountain 15' quadrangle is located just south of the Hayfork quadrangle and just east of the Pickett Peak quadrangle. [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. 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. [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. Lakesite 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. Aftershocks strong enough to be felt occurred until 1817. 5.2 km from 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 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. Rapid deposition and the resulting enormous thickness of the post-rift sediments caused them to collapse and spread seaward. Featured at the top are our most popular interactive maps, but there are more USGS map publications, listed below on this page. [9] Subscribe to Earthquake Notifications ShakeAlert Earthquake Early Warning Significant Earthquakes, Past 30 Days Significant Earthquakes Archive [1][5] This province is further subdivided into the Piedmont, Valley and Ridge, and Appalachian Plateaus provinces. The only damaging earthquakes reported through 1989 in this huge tract of land are four MMI VI earthquakes in westernmost Florida (1780), southern Louisiana (1930), and eastern Texas (1891, 1932) (Stover and Coffman, 1993 #1986). And then you have little shifts and thats what ends up initiating your earthquakes.. The quake damaged the civic building at Henderson, Kentucky, and was felt in 23 states. The interactive map to below shows epicenters of historical Alabama earthquakes since 1886 and surface and basement faults. Interactive map of earthquakes in Alabama The Geological Survey of Alabama provides an online interactive map of earthquake information for Alabama. For the most up-to-date information, please refer to the interactive fault map. 0.2 km from Alabama shakes: Small earthquakes common, potential for big one exists. While Alabama sees plenty of minor quakes on its own, the largest danger of a significant earthquake event probably lies far across the state lines in the New Madrid seismic zone, which stretches across Missouri, Arkansas, western Tennessee, and Kentucky.

Extensive oil and gas deposits have been developed in the southern portion of the state, Mobile Bay, and coastal state waters. Official websites use .gov East Brainerd A map of the fault lines database from the United States Geological Survey. Mississippi line. Why were Mexican workers able to find jobs in the Southwest? The GSA reported: "Near the epicenter, chimneys were knocked down, windows. Due to the fault, the blocks can easily move, which is what is happening when an earthquake occurs. Map showing Quaternary faults in the western U.S. and Pacific Ocean. (6.2 miles), 2022-08-13 10:16:53 UTC the New York-Alabama Lineament, which is a major magnetic fault Sort. major geological fault line. Stevenson at 06:42 December 04, 2022 UTC, Location: Multiple landslides and rock avalanches occurred in the Alaska Range and Black Rapids Glacier. The American Geosciences Institute represents and serves the geoscience community by providing collaborative leadership and information to connect Earth, science, and people. at 12:50 August 21, 2021 UTC, Location: Accordingly, the fault belt is assigned to class B. 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. By studying evidence of past quakes and closely monitoring ground motion and current earthquake activity, scientists attempt to understand their causes and recurrence intervals. The 15 May 2020, M6.5 Monte Cristo Range earthquake was the largest earthquake in Nevada in over 66 years and occurred in a sparsely populated area of western Nevada about 74 km southeast of the town of Hawthorne. This fault line is called the Quaternary a year. Dalton 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. Dalton The orange, bean-shaped area represents the dense, magnetic body of rock on the east side of the fault beneath Santa Rosa. How did you use the result to determine who walked fastest and slowest? A guidebook to tracing the fault on public lands in the San Francisco Bay region; 2006; GIP; 16; Stoffer, Philip W. This fault line is called the Quaternary fault. Dalton This page was last edited on 30 January 2023, at 06:41. At the time of the quake, it was the biggest recorded quake with an epicenter in Illinois in that state's recorded history. The 1895 event had its epicenter near Charleston, Missouri. [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. There hasn't been a major earthquake since. occasions. Interactive fault map and comprehensive geologically based information on known or suspected active faults and folds in the United States. [1][5] This province is further divided into the Interior Low Plateaus province. at 06:44 November 22, 2022 UTC, Location: [25], Beginning in February 1989, self-proclaimed climatologist Iben Browning, who claimed to have predicted the 1980 eruption of Mount St. Helens and the 1989 Loma Prieta earthquake predicted a 50% probability of a magnitude 6.5 to 7.5 earthquake in the New Madrid area sometime between December 1 and December 5, 1990. 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. [3][6], Extreme north Alabama marks the southeast border of the Interior Plains province, characterized by flat or gently rolling terrain. The USGS Earthquake Hazards Program is part of the National Earthquake Hazards Reduction Program (NEHRP), established by Congress in 1977, and the USGS Advanced National Seismic System (ANSS) was established by Congress as a NEHRP facility. [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. (9.2 miles), 2023-02-06 13:24:21 UTC National Earthquake Hazards Reduction Program (NEHRP).
