Earthquake Insight Field Trip Planned for April 10

A few seats still available!

Tuesday, April 10, the U.S. Geological Survey will host the eighth annual Earthquake Insight Field Trip.  This one-day outreach event will start and end in Memphis, Tenn.  Field trip participants will learn about the earthquake history of the central U.S. and current exposures to earthquake hazards in this area.  The trip is especially for non-scientists, such as emergency planners, business leaders, elected officials, media, finance and equity professionals, risk managers, portfolio managers, lenders, and business continuity planners.  The field trip will be led by geoscientists, engineers, and emergency planners who are active in current research and practice.  The final report of the first Earthquake Insight Field Trip, which was in 2005, is posted online. The route and content of each Earthquake Insight Field Trip since then has been unique.  For more information about this year’s event, visit this website, email Phyllis Steckel, or call 636-239-4013.

Nearly 900 people in 21 states reported last Tuesday’s Missouri earthquake

More than 866 people in 21 states reported last Tuesday’s earthquake

M3.9 earthquake, Feb. 21, 2012 near Sikeston, Mo.Following last Tuesday’s magnitude 4.0 earthquake near Sikeston, Missouri, nearly 900 people in 21 states reported shaking to the U.S. Geological Survey’s “Did you feel it?” website. 

The earthquake was originally reported by USGS to have been magnitude 4.0, but was later downgraded to M3.9.  Three subsequent quakes occurred in the following order; a magnitude 1.8 at 6:18 AM, a magnitude 2.4 at 1:05 PM and a magnitude 2.0 at 12:38 PM.  An earthquake with a magnitude 2.0 is about the level at which one can typically be felt.

Over the past five years Missouri has experienced more than 24 earthquakes of that magnitude or greater.  February is Earthquake Awareness Month in Missouri.  Learn more about earthquake potential in Missouri.  –Joe

Learn about Earthquakes Feb. 18 at Onondaga Cave State Park

Plan to attend — February is Earthquake Awareness Month in Missouri

“The Earth Moves Under Our Feet,” an event in recognition of Earthquake Awareness Month, will be held Saturday, Feb. 18 at Onondaga Cave State Park near Leasburg.  The free event, scheduled from 10:30 a.m. to noon, is sponsored by the Missouri Department of Natural Resources’ Division of Geology and Land Survey and Missouri State Parks.

The park’s visitor center will feature displays relating to earthquakes for visitors to explore. At 10:30 a.m., Edie Starbuck, one of our geologists, will present a program on earthquake basics, history, earthquake preparedness and the effects earthquakes have had, and will have, on the land and human population. This program will include an introduction to the State Emergency Management Agency programs related to earthquakes. After the program, a video about earthquakes in the Midwest will be shown. There will be time for questions and answers.

Thanks for Participating in the ShakeOut

Almost 480,000 Missourians registered to participate in this important exercise

Thanks to everyone who participated Tuesday, Feb. 7, 2012, in the 2012 Great Central U.S. ShakeOut! More than 2.4 million people across nine states participated by practicing DROPPING to the ground, taking COVER by getting under a sturdy desk or table, and HOLDING ON until the exercise ended.

Some of our staff spent part of the morning at Immanuel Lutheran School where Brenna McDonald, one of our geologists, taught about earthquakes and preparedness.  Afterword, Brenna and Hylan Beydler, our information officer, led the students in participating in the Great Central ShakeOut.

This year marks the 200th anniversary of a series three earthquakes believed to have been magnitude 7.0 or larger that occurred near the southeast Missouri town of New Madrid. Learn more about earthquake potential in Missouri. Visit the ShakeOut website for more information about preparedness.

Earthquake – Feb. 7, 1812 at 3:45 a.m. CST

200 Years Ago Today

February 7, 2012 marks the 200th anniversary of the third and final principal earthquake along the New Madrid Seismic Zone in the winter of 1811-1812.  This earthquake, which was preceded by a number of noticeably significant shakes, occurred about 3:45 a.m. and is believed to have equaled or exceeded the magnitude of the two previous principal shocks of December 16, 1811 and January 23, 1812 (estimated at magnitude 7.0 or greater).

It is reported that the town of New Madrid, Mo. was completely destroyed and the general landscape was characterized by ground warping, earth fissures, sandblows, and landslides.  An eyewitness account from a citizen living in Cincinnati, Ohio noted that this earthquake caused greater ground movement than ever before seen and toppled many chimneys and damaged homes.  Another account from a settler living near present-day Louisville, Kentucky suggested that “If we do not get away from here, the ground is going to eat us alive.”

One of the most notable occurrences during this February 7 earthquake was the subsidence of land.  In some instances it was reported that the land subsided up to 6 meters (19 feet) and altered the natural drainages in the area ultimately creating several lakes.  The most significant and widely known of these was Reelfoot Lake in Tennessee.

The U.S. Geological Survey has a number of photos that depict the area taken about 100 years after the earthquakes.

February is Earthquake Awareness Month in Missouri

Earthquake Awareness Month

Two hundred years ago, Missourians experienced powerful earthquakes in the Bootheel region of the state. Three earthquakes, estimated at magnitude 7.0 or greater occurred along the New Madrid fault in the winter of 1811-12.

Small earthquakes occur in the region daily. While earthquakes along the fault do not cause loss of life, they are a natural hazard that no one can predict. Fortunately, there are things everyone can do to be better prepared.

Each February Missouri observes Earthquake Awareness Month. To raise awareness, geologists with the Missouri Department of Natural Resources will partner with local, state and federal agencies and organizations by participating in a number of public activities by providing scientific data about the New Madrid Seismic Zone, mapping for risk assessment, and geologic information about the basics of earthquakes. Missourians are encouraged to attend any of the following public events. Other venues and activities may be added.
