Eocene to Holocene (Szabo and Copeland, 1988 #1946; DuBar and others, 1991 #2010). Alabama's fault lines cause frequent small earthquakes, but have the potential to cause much more damage. The 3.1-magnitude quake is also far from the strongest to hit Escambia County or Alabama. Triassic-Jurassic rifting and sedimentation, including deposition of the Louann Salt, led to Mesozoic growth faulting and salt tectonism. 10.2 km from Magnitude estimates and epicenters are based on interpretations of historical accounts and may vary.

[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. Knowing these major and active Philippine fault lines, it becomes clear why earthquakes frequent different parts of the country.

The orange, bean-shaped area represents the dense, magnetic body of rock on the east side of the fault beneath Santa Rosa. Dalton Earthquake magnitudes are calculated on a logarithmic scale, so a magnitude 3.0 quake is 10 times more powerful than a 2.0. [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.

[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. 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). 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). Android | iOS version Why is there advertising on this site? Potential Effects of Shaking. The New Madrid fault system was responsible for the 181112 New Madrid earthquakes, and has the potential to produce large earthquakes in the future. The last time it probably slipped was 10 thousand, 12 thousand years ago" said Velasco. in the U.S. east of the Rocky Mountains.

"And from what they've been able to determine is that these events occur on an average cycle of 200-300 years.". Sandy Ebersole, who heads the division of the Geological Survey of Alabama that documents and studies earthquakes in the state, said its not unusual or surprising to have multiple small-scale earthquakes in quick succession in the state. 13.2 km from AGI's Critical Issues Program is generously underwritten in memory of Charles L. Weiner. [7] [8] The largest earthquake in recorded Alabama history measured an estimated magnitude of 5.1 and occurred October 18, 1916 near Irondale, and resulted in widespread panic, damage to structures, and dramatic changes in water well levels. Did You Feel It? [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. 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. SDC/Map Color. (7.2 miles), 2021-12-22 06:20:48 UTC 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.
