5.2 km from 2 earthquakes in the past 30 days. 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. 14.2 km from "[27] Despite the lack of scientific support, Browning's prediction was widely reported in international media, causing public alarm. 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. 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). The earthquake produced surface rupture distributed across a 28-km-long zone along the eastward projection of the Candelaria fault in the Mina deflection of the central Walker Lane. Gulf-margin normal faults, Alabama and Florida (Class B) No. Epicenter at 34.684, -85.073 Stephenson, W.J., K.M. reason i say this , is because the other night on What are the disadvantages of shielding a thermometer?

Vol. The New Madrid Seismic Zone (/mdrd/), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri. [3][5], This relative weakness is important, because it would allow the relatively small eastwest compressive forces associated with the continuing westward continental drift of the North American Plate to reactivate old faults around New Madrid, making the area unusually prone to earthquakes in spite of it being far from the nearest tectonic plate boundary. USGS The USGS has a faults website that includes an interactive fault map that allows users to views a map. 13.2 km from 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. Latest earthquakes map and list (past 24 hours, M2.5+) from the ANSS (Advanced National Seismic System). However, there are several intraplate faults running through the state that can cause frequent small earthquakes, and rare larger ones. 2.1 earthquake - 6.2 mi south of LaFayette, Walker County, Georgia, USA, on Monday, Feb 6, 2023 at 8:24 am (GMT -5). at a depth of 13 kilometers (km) approximately 25 km southwest of the capital, Port-au-Prince. [27] The United States Geological Survey (USGS) requested an evaluation of the prediction by an advisory board of earth scientists, who concluded, "the prediction does not have scientific validity. Turkey's two main fault zones the . There's one database for Class A and B faults and another for Class C and D faults. These maps are used in determining building seismic codes, insurance rates, and other 8.2 km from The recent Virginia Click here to access the latest map that includes induced earthquake hazards. 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. It can be particularly helpful for those who want to know what their risk of experiencing an earthquake is where they live. "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. at 12:08 September 11, 2021 UTC, Location: 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. 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. 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 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. [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. Aftershocks strong enough to be felt occurred until 1817. American Geologist. On this Wikipedia the language links are at the top of the page across from the article title. A recent . Newest First. A strike-slip fault is when two blocks slip past one another, like the San Andreas Fault line. (8.2 miles), 2022-11-22 06:44:43 UTC 2023-02-24 07:37:18 UTC (6.2 miles), 2022-09-04 21:51:08 UTC It is southwest of the Wabash Valley Seismic Zone. (8.2 miles), 2022-12-04 06:16:37 UTC Epicenter at 35.046, -85.128 The fault could trigger the "Big One" and be followed by a tsunami, according to PHIVOLCS. The map also shows potentially active faults from a separate 2014 report (click here to download). This map shows areas of seismic risk from high (red) to low (grayish-green). American Geosciences Institute. Alabama's fault lines cause frequent small earthquakes, but have the potential to cause much more damage. Shedlock, and J.K. Odum. 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. Dalton [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. 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. If you live in a high-risk area or near a fault line in the Philippines, go beyond doing the duck, cover, and hold. (10.2 miles), 2022-01-19 05:33:43 UTC 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. 4.2 km from The post-rift sequence as a whole is at least 9-11 km thick throughout the Coastal zone (Salvador, 1991 #2020). Dalton at 05:33 January 19, 2022 UTC, Location: Here a map of the major earthquake fault lines in the USA. Rapid deposition and the resulting enormous thickness of the post-rift sediments caused them to collapse and spread seaward. For the most up-to-date information, please refer to the interactive fault map. 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. Trion The various colors and line types indicate different ages of the most recent earthquakes on the fault and how well the location of the fault is constrained. [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. [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]. Interactive map of earthquakes in Alabama The Geological Survey of Alabama provides an online interactive map of earthquake information for Alabama.

(8.2 miles), 2022-12-04 06:42:50 UTC 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. The USGS and its partners monitor and report earthquakes, assess earthquake impacts and hazards, and perform research into the causes and effects of earthquakes. 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). The report found that there would be significant damage in the eight states studied Alabama, Arkansas, Illinois, Indiana, Kentucky, Mississippi, Missouri, and Tennessee with the probability of additional damage in states farther from the NMSZ. 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.
