Joplin, Missouri
Each June, Joplin hosts the Boomtown Run, a half marathon, 5K, and children's run. The event attracts runners from across the country, and features USTA certified courses which start and end in the historic downtown area. Celebrity runners featured at the prerace banquet have included Bart Yasso, Sarah Reinerston, Suzy Favor-Hamilton, and Jeff Galloway. In 2011, due to the devastating EF5 tornado that struck Joplin on May 22, just three weeks before the run, the event was transformed in the Boomtown Run Day of Service. About 270 individuals registered for the race after the tornado struck, knowing their proceeds would benefit tornado recovery. On June 11, about 270 registered runners and volunteers turned out to help clean debris and sort donations, contributing more than 1,200 hours of service. On August 7, 2012, the Village of Silver Creek and the City of Joplin voted to have Silver Creek annexed into Joplin City limits.
Tornado climatology
On average, the United States experiences 100,000 thunderstorms each year, resulting in more than 1,200 tornadoes and approximately 50 deaths per year. The deadliest U.S. tornado recorded is the 18 March 1925, Tri-State Tornado that swept across southeastern Missouri, southern Illinois and southern Indiana, killing 695 people. The biggest tornado outbreak on record—with 353 tornadoes over the course of just 3 1/2 days, including four F5 and eleven F4 tornadoes—occurred starting on 25 April 2011 and intensifying on 26 April and especially the record-breaking day of 27 April before ending on 28 April. It is referred to as the 2011 Super Outbreak. Previously, the record was 148 tornadoes, dubbed the 1974 Super Outbreak. Another such significant storm system was the Palm Sunday tornado outbreak of 1965, which affected the United States Midwest on 11 April 1965. A series of continuous tornado outbreaks is known as a tornado outbreak sequence, with significant occurrences in May 1917, 1930, 1949, and 2003.
