Emergency communication system
161 people were killed and at least 990 injured when an EF5 multiple-vortex tornado hit Joplin, Missouri. Because Joplin is located in a tornado-heavy area of the country, many people considered the tornado sirens routine and ignored them. Instead, many residents waited until they received confirmation from another, non-routine, source, such as seeing the tornado, a radio or TV report, or hearing a second siren. In the aftermath, an assessment team recommended that emergency warnings take risk perception into account to convey a sense of urgency. NOAA Officials are considering ways to change the warning system to distinguish smaller tornadoes from more deadly ones.
Mercy Hospital Joplin
Mere hours after one of the deadliest recorded tornadoes in U.S. history hit Joplin, the Missouri Medical Assistance Team (DMAT) started working to create a plan to help the survivors. The following Wednesday, DMAT deployed their 8,000 square foot field hospital to temporarily replace the destroyed hospital. Six days after the tornado, on May 29, 2011 St. John's medical staff gave medical treatment to their community in the BLU-MED field hospital. This temporary hospital is now the home of the Kansas City University-Joplin School of Osteopathic Medicine.
