Earthquakes in Missouri Mid-America Contingency Planning Forum Fall Symposium September 17, 2015 Ballwin, MO
Missouri’s Earthquake Program • Outreach and Education (Preparedness) • Earthquake Awareness Month during February • Great Central U.S. ShakeOut during October • Catastrophic Planning Efforts • MO Seismic Safety Commission • Structural Assessment & Visual Evaluation (SAVE) Coalition • Support for Earthquake Exercises

St. Louis Area Earthquakes Since 1811 at least a dozen earthquakes have caused minor damage in St. Louis. (Public domain information: Saint Louis University Earthquake Center, St. Louis, Mo., 1999, http://www.eas.slu.edu/Earthquake_Center/EQInfo/Flyers/central_u.html)

New Madrid Seismic Zone Catastrophic Planning: • The Response Challenges Approximately 7 million people at high risk • No notice event that is not commonly recognized • Large area of impact - 126,575 Sq. Miles • Multiple jurisdictions with multiple governors • Significant infrastructure impacts • Response challenges multiple earthquakes/ aftershocks • Poor situational awareness • Security demands • Mass care/shelter needs • Major housing, evacuation, & relocation needs • Urban & Isolated areas St. Louis 348 K 2 mil metro 5 Million Rural Pop. 160 – 200 Cities IL IN MO KY TN AR AL MS Memphis 655K 1.3 mil metro
Planning: New Madrid Seismic Zone Concerns • Earthquakes are no-notice events • Midwest geology allows quakes to be felt over a much wider area than those in places like California • Softer soils commonly located in river valleys amplify the earthquake effects • Those same soils can also liquefy for a short time • Many older buildings are made of unreinforced masonry and are vulnerable to shaking • The public generally does not prepare for “low probability, high-consequence events” • The effects of such an earthquake or earthquakes could be far beyond other disasters we have faced in Missouri • Missouri will not be the only state affected by these quakes and so will not be able to assist neighboring states, while competing with them for outside resources

Results • More than 7,700 Structures Inspected • 36% Unsafe • 6% Restricted Use • 58% Did Not Present Life Safety Problems
Exercising Our Plans • October 15, 2015 – Great Central U.S. ShakeOut earthquake drill • October 16-17, 2015 – SAVE Coalition exercise at Jefferson Barracks • August 2016 – National-Level Mass Care earthquake exercise in Missouri
