Emergency response teams from across the state were in Sedalia on Tuesday to help fake victims of a fake earthquake as part of a National Mass Care Series Exercise.  From Monday through Wednesday, teams are testing plans for evacuating and sheltering potential victims of a New Madrid Seismic Zone earthquake. The zone, located in New Madrid, Missouri, in the southern part of the state, has not produced a major earthquake since 1812, but the exercises are meant to help responders be prepared in case another ever occurs. “What I understand is that they have been able to look back, digging in the ground, and they think it goes off in a big event once every 250 years,” said Sedalia-Pettis County Emergency Management Agency Director Dave Clippert.
