As earthquakes continue to occur on a daily basis in the central U.S.—with nearly 2,000 small tremors per year—CUSEC and emergency management officials in our Member States remind citizens and communities about the earthquake risk by designating February as Earthquake Awareness Month. During the month of February, and into March, CUSEC and our states will be involved with several events (listed below, as they become available) intended to educate and train the public, private sector, first responders, and government officials.
February 1-28 – Earthquake Awareness Month
February 19 – New Madrid Planning Workshop; N. Little Rock, Arkansas
February 20 – QuakeSmart for Business Workshop; Memphis, Tennessee
February 21 – CUSEC Board of Directors Meeting; Virtual
February 27 – Paragould Disaster Summit; Paragould, Arkansas
March 6 – Association of CUSEC State Geologists Meeting; Conway, Arkansas
March 7 – National Seismic Hazard Model Workshop; Conway, Arkansas
March 18 – Missouri Earthquake Summit; Cape Girardeau, Missouri
March 19 – CUSEC Transportation & Mass Care Workshop; Cape Girardeau, Missouri
March 21 – On-Site Leader Training; Franklin, Tennessee
Also, February 7 is the anniversary of the last of the earthquakes that struck the central U.S. in the winter of 1811-12. According to the US Geological Survey:
This sequence of three very large earthquakes is usually referred to as the New Madrid earthquakes, after the Missouri town that was the largest settlement on the Mississippi River between St. Louis, Missouri and Natchez, Mississippi. On the basis of the large area of damage (600,000 square kilometers), the widespread area of perceptibility (5,000,000 square kilometers), and the complex physiographic changes that occurred, the New Madrid earthquakes of 1811-1812 rank as some of the largest in the United States since its settlement by Europeans.
While scientists say that there is as about probability of a reoccurrence of the 1811-12 earthquakes within any 50-year window, they also estimate that there is as much as 40% chance of a M6.0 or greater earthquake occurring in the central U.S. within the same period of time. About 200 earthquakes occur in the central U.S. every year-many of which go unnoticed. And while the primary focus remains on the NMSZ, it is not the only area of concern. Earthquakes are also occurring along the Wabash Valley and East Tennessee Seismic Zones and in Oklahoma, Kansas, Ohio, and Texas.
