Preparing and planning is essential for earthquake safety. The New Madrid Seismic Zone experiences about 200 small earthquakes a year. Unlike some other disasters, earthquakes provide no advance warning. The State Emergency Management Agency (SEMA) works with many government and voluntary agencies, businesses and schools to ensure a coordinated, effective response to the challenges a major earthquake would pose.

- Award winning preparedness videos created by Missouri school children – Kindergarten through 12th grade students across Missouri were encouraged to share their knowledge by creating videos that educate others about preparing for an earthquake. The contest was sponsored by the department’s Missouri Geological Survey. Winners chosen from three categories: K-4, 5-8 and 9-12 grades. Seventh grade students Miranda Kaleel and Lauren Whittier from Rockwood School District’s Selvidge Middle School in Ballwin, won the 5-8 grade category and were named grand prize winner for their silent movie video that demonstrates the steps one should take in the event of an earthquake. The video was a class project for gifted students. Theresa Stockman is their teacher. Kaleel and Whittier were invited to the Carnahan High School of the Future, St. Louis, to practice Drop, Cover, and Hold On during the Great Central U.S. ShakeOut on April 28, 2011. Gov. Jay Nixon, U.S. Homeland Security Secretary Janet Napolitano and U.S. Education Department Secretary Arne Duncan fielded questions Carnahan School for the Future and Selvidge Middle School students posed. Kaleel and Whittier were recognized for their winning video by Secretaries Napolitano and Duncan. The Selvidge Middle School video is the first video on the channel. The second is David Wiles’ video and the third is Lake Spring 4H Club’s video. The videos will be featured at awareness events during the month of February, which is Earthquake Awareness Month in Missouri. Winners were awarded a Missouri Rock and Mineral Set provided by the department’s Missouri Geological Survey, and a Quake-Catcher earthquake sensor donated by Stanford University’s Quake-Catcher Network. The grand prize winner was awarded a Kodak© Playsport Video Camera, which was made possible through a grant from the Central United States Earthquake Consortium. The grand prize winning video also was shown during the 2011 Earth Day celebration at the Capitol in Jefferson City Friday, April 29.
