[1][2] The Geological Survey of Alabama breaks these provinces down into more specific physiographic provinces. Accordingly, the fault belt is assigned to class B. In October 2009, a team composed of University of Illinois and Virginia Tech researchers headed by Amr S. Elnashai, funded by the Federal Emergency Management Agency, considered a scenario where all three segments of the New Madrid fault ruptured simultaneously with a total earthquake magnitude of 7.7. Consistent with the stress field in the post-rift sequence, the normal-faulting focal mechanism of the 1997, M 4.9 earthquake in southwestern Alabama indicated south-southwest extension (Chang and others, 1998 #1806). 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. Ground shaking is the most powerful predictor of damage from an earthquake. Earthquake Hazard in the New Madrid Seismic Zone Remains a Concern USGS (2009). "A fault that could potentially slip in modern times. These maps are used in determining building seismic codes, insurance rates, and other public decisions. Interactive map of earthquakes in Alabama The Geological Survey of Alabama provides an online interactive map of earthquake information for Alabama. The most recent quake registered as a magnitude 4.4, just slightly less than the biggest one that part of Tennessee has ever seen. Alabama's fault lines cause frequent small earthquakes, but have the potential to cause much more damage. [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. [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. What are the disadvantages of shielding a thermometer? [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.

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). The period passed with no major earthquake activity in New Madrid or along the 120-mile (190km) fault line. at 18:34 December 11, 2021 UTC, Location: 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. Potential Effects of Shaking. East Franklin Mountain Fault Courtesy of Dr. Jose Hurtado. The data behind it was acquired in the early hours of Friday by the European Union's Sentinel-1A satellite as it traversed north to south over Turkey at an altitude of 700km (435 miles). In early to middle Mesozoic time, the opening of the Gulf of Mexico formed a south-facing, rifted, passive margin at the southern edge of North America (DuBar and others, 1991 #2010; Salvador, 1991 #2019; Salvador, 1991 #2020). [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. at 06:50 November 06, 2021 UTC, Location: 5.2 km from Turkey's two main fault zones the .

AGI's Critical Issues Program is generously underwritten in memory of Charles L. Weiner. 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. Aliceville What are the two applications of bifilar suspension? Also, generalized fault data used in the hazard maps. 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. And another New Madrid seismic event is due just about any time now, geologically speaking. There's one database for Class A and B faults and another for Class C and D faults. SDC/Map Color.
