Epicenter at 35.296, -85.484 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 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. [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. Furthermore, some of the sparse seismicity in the normal-fault belt may be artificially induced. Hazel Green "Documentation for the 2014 Update of the United States National Seismic Hazard Maps", Earthquake Hazard in the New Madrid Seismic Zone Remains a Concern, U. Memphis, TN, Center for Earthquake Research and Information (CERI) comprehensive references for the 18111812 earthquakes, Space geodetic evidence for rapid strain rates in the New Madrid seismic zone of Central USA (PDF), https://en.wikipedia.org/w/index.php?title=New_Madrid_Seismic_Zone&oldid=1136422696. Alabama's fault lines cause frequent small earthquakes, but have the potential to cause much more damage. This earthquake, which occurred Dec. 20 about three miles outside of Bryant, Ala. near the Tennessee border, had a magnitude of just 1.8, meaning it would be very hard to detect without. Kimball Share sensitive information only on official, secure websites. 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 at 21:51 September 04, 2022 UTC, Location: [1][5] This province is further divided into the Interior Low Plateaus province. The map clearly identifies the locations of the great earthquakes (M8.0 and larger) and the, This report provides trench photomosaics, logs and related site information, age data, and earthquake event evidence from three paleoseismic trench sites on the Bear River Fault Zone. The American Geosciences Institute represents and serves the geoscience community by providing collaborative leadership and information to connect Earth, science, and people. The major earthquake and large aftershock in Turkey on Monday are two of more than 70 quakes of magnitude 6.5 or higher recorded in the region since 1900. Dalton 8.2 km from Join half a million readers enjoying Newsweek's free newsletters. 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. in the U.S. east of the Rocky Mountains. [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. 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. Magnitude estimates and epicenters are based on interpretations of historical accounts and may vary. Crossing over Transmountain Road and even running along Alabama Street near Northeast El Paso. The equipment recorded more than 200 earthquakes during that time, ranging from M 0.8 to M 4. 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). Note that most faults that can affect residents are either onshore or just offshore. [1], Earthquakes that occur in the New Madrid Seismic Zone potentially threaten parts of seven American states: Illinois, Indiana, Missouri, Arkansas, Kentucky, Tennessee, and Mississippi.[2].

Subscribe to Earthquake Notifications ShakeAlert Earthquake Early Warning Significant Earthquakes, Past 30 Days Significant Earthquakes Archive This fault line is called the Quaternary fault. Faults with evidence of Holocene (about 10,000 . (3.2 miles), 2021-02-01 06:19:25 UTC 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. 13.2 km from 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). Sylvania Alabama shakes: Small earthquakes common, potential for big one exists. 1 earthquake in the past 7 days. All rights reserved. [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. Privacy Policy, West Virginia Geological & Economic Survey, Interactive map of California earthquake hazard zones, Interactive map of geothermal resources in West Virginia, Interactive map of natural hazards in Nevada, Interactive map of earthquakes around the world, Interactive map of earthquakes in Montana, Visualization of earthquake risk in California. Epicenter at 35.226, -85.073 [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. at 06:20 December 22, 2021 UTC, Location: The New Madrid fault system was responsible for the 181112 New Madrid earthquakes, and has the potential to produce large earthquakes in the future. Trion at 06:12 November 07, 2021 UTC, Location: at 06:37 April 07, 2021 UTC, Location: Multiple landslides and rock avalanches occurred in the Alaska Range and Black Rapids Glacier. The GSA reported: "Near the epicenter, chimneys were knocked down, windows. C/Yellow. The New Madrid fault system was responsible for the 1811-12 New Madrid earthquakes . [12] The Cahaba Basin and Black Warrior Basin in central Alabama produce coalbed methane. fault. Who makes the plaid blue coat Jesse stone wears in Sea Change? However, geologists are concerned with We do have episodes of this kind of seismic activity clusters once in a while, Ebersole said. Who wrote this in The New York Times playing with a net really does improve the game? The 3.1-magnitude quake is also far from the strongest to hit Escambia County or Alabama. 14.2 km from This almighty quake caused extensive damage to the transportation systems in central Alaska. (6.2 miles), 2022-09-04 21:51:08 UTC at 09:32 May 15, 2022 UTC, Location: However, there are several intraplate faults running through the state that can cause frequent small earthquakes, and rare larger ones. Epicenter at 35.046, -85.128 These maps are used in determining building seismic codes, insurance rates, and other public decisions. It includes information like how old the faults are and users can also click on the fault area to learn more about the specific fault there. For the purposes of his compilation, the Gulf Coast faults are divided in four large groups because they number in the hundreds. 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. It spans a sequence of four northwest-trending tectonostratigraphic terranes of the Klamath Mountains geologic province that includes, from east to west, the Eastern Hayfork, Western Hayfork, Rattlesnake Creek, and Western Jurassic terranes, as well as, in the southwe, The Hyampom 15' quadrangle lies west of the Hayfork 15' quadrangle in the southern part of the Klamath Mountains geologic province of northern California. 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. 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). Fault lines are really located everywhere, but it's usually the 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). Epicenter at 34.758, -85.368 Since 1812, frequent smaller earthquakes have been recorded in the area. Earthquakes occur nearly every day in Washington. (10.2 miles), 2021-03-14 11:22:09 UTC Epicenter at 34.687, -85.077 Earthquake Hazard. #1806 Chang, T.M., Ammon, C.J., and Herrmann, R.B., 1998, Faulting parameters of the October 24, 1997 southern Alabama earthquake [abs. Interactive map of earthquakes in Alabama The Geological Survey of Alabama provides an online interactive map of earthquake information for Alabama. [27], The lack of apparent land movement along the New Madrid fault system has long puzzled scientists. SDC/Map Color. 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. 13.2 km from what type of danger zone is needed for this exercise. [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 map provides the locations, dates, and magnitudes of historical earthquakes, as well as highlighting recent earthquakes. at 06:50 November 06, 2021 UTC, Location: All rights reserved (About Us). The northeast corner of the state is subject to the greatest peak accelerations due to the presence of the East Tennessee Seismic Zone. Subsequently, the rifted margin was buried beneath the thick, Middle Jurassic, Louann Salt and an overlying, carbonate and clastic, marine sequence that continues to accumulate today. Only List Earthquakes Shown on Map . Tap/click on "gear icon" for options and settings. (0.2 miles), 2022-04-21 18:01:25 UTC In 2009, two studies based on eight years of GPS measurements indicated that the faults were moving at no more than 0.2 mm (0.008 in.) There is one major fault line that runs through Alabama and the rest of the gulf coast. [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. Also, generalized fault data used in the hazard maps. 8.2 km from Map showing Quaternary faults in the western U.S. and Pacific Ocean. major fault lines that you need to worry about.
