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.
Erica Tremblay
In 2012, she released "Heartland: A Portrait of Survival." The film documents the effects of the 2011 Joplin tornado which destroyed a quarter of the city and caused about $2.8 billion worth of damage. Tremblay, who was living in Los Angeles at the time but had previously lived in Joplin, had relatives still living in her hometown. She traveled to the town with a film crew and documented the aftermath for a four-week period. The film, which features several stories like the Joplin Found Photos project, was shown at the Omaha Film Festival, and at St. Louis International Film Festival.
