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.
Joplin, Missouri
St. John's Regional Medical Center was damaged, and demolished in 2012. The Missouri Disaster Medical Assistance Team temporarily replaced the demolished St. John's Regional Medical Center with a mobile hospital until the permanent hospital was rebuilt. The local high school, Joplin High School, was totally destroyed, as well. A total of 161 people died from tornado-related injuries as of the end of July 2011. Communications were lost and power was knocked out to many areas. An official statement from the National Weather Service has categorized the tornado as an EF5. On Sunday, May 29, President Barack Obama, Missouri Governor Jay Nixon, and Federal Emergency Management Agency Director Craig Fugate visited and toured Joplin to see what the damage looked like and attended a memorial service for the deceased. Later that day, the city held a moment of silence at 5:41 pm, to mark the time the tornado struck. The area was declared a federal disaster area.
