Therefore, the natural seismicity rate in the normal-fault belt might be even less than the recent historical record would indicate. (11.2 miles), 2021-11-06 06:50:03 UTC 14.2 km from Multiple landslides and rock avalanches occurred in the Alaska Range and Black Rapids Glacier. [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. Thorsby What are the disadvantages of shielding a thermometer? Copyright 2023. Its now been 207 years since the last major New Madrid seismic event. Community Rules apply to all content you upload or otherwise submit to this site. Triassic-Jurassic rifting and sedimentation, including deposition of the Louann Salt, led to Mesozoic growth faulting and salt tectonism. At the coastline, the sequence is at least 10 km thick west of the Mississippi River and at least 5 km thick farther east. Extensive oil and gas deposits have been developed in the southern portion of the state, Mobile Bay, and coastal state waters. These were interpreted as clear signals of the 18111812 earthquake series in tree rings. That area was sparsely populated then (the city of Memphis had not yet been founded), but similar quakes today would cause massive damage, potentially stretching into north Alabama. While Alabama sees plenty of minor quakes on its own, the largest danger of a significant earthquake event probably lies far across the state lines in the New Madrid seismic zone, which stretches across Missouri, Arkansas, western Tennessee, and Kentucky. Clanton All rights reserved. Alabama shakes: Small earthquakes common, potential for big one exists. 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. at 00:51 August 13, 2022 UTC, Location: at 05:33 January 19, 2022 UTC, Location: The Kansas Earthquakes page on the KGS website includes a continuously updated interactive map that shows where earthquakes have occurred in the state since 2015.
