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. We do have episodes of this kind of seismic activity clusters once in a while, Ebersole said. occasions. 2023 Advance Local Media LLC. Tap/click on "gear icon" for options and settings.

Epicenter at 34.579, -85.892 Although some of these ideas have gained some acceptance among researchers, they have not been accepted by the National Earthquake Prediction Evaluation Council, which advises the USGS. 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). However, geologists are concerned with Gulf-margin normal faults, Alabama and Florida (Class B) No. These listric normal faults, their splays, and their antithetic and transfer faults make up the belt of gulf-margin normal faults described here.

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. 13.2 km from Multiple landslides and rock avalanches occurred in the Alaska Range and Black Rapids Glacier. The post-rift sequence and its belt of gulf-margin normal faults may be mechanically decoupled from the underlying crust. FAQ - Frequently Asked Questions By studying evidence of past quakes and closely monitoring ground motion and current earthquake activity, scientists attempt to understand their causes and recurrence intervals. 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.

(11.2 miles), 2021-11-06 06:50:03 UTC See below for an embedded map of all documented Alabama earthquakes dating back to 1886. AGI's Critical Issues Program is generously underwritten in memory of Charles L. Weiner. "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.

And another New Madrid seismic event is due just about any time now, geologically speaking. 20, p. 207, "East Gulf Coastal Plain Ecoregional Plan", https://en.wikipedia.org/w/index.php?title=Geology_of_Alabama&oldid=1106112936, Articles with dead external links from January 2017, Articles with permanently dead external links, Articles with dead external links from November 2018, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 23 August 2022, at 07:29. fault. The quake damaged the civic building at Henderson, Kentucky, and was felt in 23 states. 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.) The equipment recorded more than 200 earthquakes during that time, ranging from M 0.8 to M 4. Source: U.S. Geological Survey Seismic Hazard Maps and Data (2014). 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. (3.2 miles), 2022-08-21 17:09:31 UTC Epicenter at 34.673, -85.103 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. 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. (11.2 miles), 2021-12-11 18:34:41 UTC 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. Dalton [14], Dendrochronology (tree ring) studies conducted on the oldest bald cypress trees growing in Reelfoot Lake found evidence of the 18111812 series in the form of fractures followed by rapid growth after their inundation, whereas cores taken from old bald cypress trees in the St. Francis sunklands showed slowed growth in the half century that followed 1812. at 06:12 November 07, 2021 UTC, Location: [28] This contrasts to the rate of slip on the San Andreas Fault, which averages up to 37mm (1.5in) a year across California. 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. [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. at 05:45 October 09, 2022 UTC, Location: [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. Eocene to Holocene (Szabo and Copeland, 1988 #1946; DuBar and others, 1991 #2010). Epicenter at 35.556, -86.55 at 13:24 February 06, 2023 UTC, Location: Rapid deposition and the resulting enormous thickness of the post-rift sediments caused them to collapse and spread seaward. at 06:19 August 25, 2021 UTC, Location: at 21:51 September 04, 2022 UTC, Location: (8.2 miles), 2022-12-04 06:16:37 UTC (1) The Interior zone of Ewing (1991 #1994) includes the entire belt except southern Louisiana, coastal Texas, and their offshore extensions. reason i say this , is because the other night on Copyright 2023. McMinnville 8.2 km from at 18:01 April 21, 2022 UTC, Location: Latest earthquakes map and list (past 24 hours, M2.5+) from the ANSS (Advanced National Seismic System). [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. [23] In 2008 in the nearby Wabash Valley Seismic Zone, a similar magnitude 5.4 earthquake occurred with its epicenter in Illinois near West Salem and Mount Carmel. Known surface faults and interpreted subsurface faults are also shown, allowing users to see the relationships between different identified faults and historical earthquakes. 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. 13.2 km from On average, one earthquake per year is large enough to be felt in the area. Post, This map illustrates 119 years of global seismicity in the context of global plate tectonics and the Earths physiography. "There's a record going back several thousands of years in the geology of the area, and the floodplains of the Mississippi River that have recorded repeating large-magnitude earthquakes in the New Madrid seismic zone," Ebersole said.

East Franklin Mountain Fault Courtesy of Dr. Jose Hurtado. 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.
