Tornado outbreak sequence of May 21–26, 2011
On May 22, a large, devastating EF5 tornado tracked through Joplin, Missouri, leaving behind catastrophic damage. It was a multiple-vortex tornado in excess of wide. Mainly the southern part of the city was affected with most structures in the area either damaged or destroyed. 162 people were killed along the path through Jasper and Newton counties in Missouri, making it the deadliest U.S. tornado since 1947, and one of the deadliest single tornadoes ever recorded. Among the most heavily damaged structures was St. John's Hospital (pictured right), which later was torn down due to the severity of the structural damage. Damages were estimated at around $2.8 billion (2011 USD).
2011 Joplin tornado
Engineers have criticized the tilt up construction of the Home Depot in which all but two of its walls collapsed in a domino effect after the tornado lifted the roof, killing seven people in the front of the store (although 28 people in the back of the store survived when those walls collapsed outwards). Home Depot officials said they disagreed with the study published by "The Kansas City Star" and said they would use the tilt up practice when they rebuild the Joplin store. On June 1, The Home Depot said it would have a new temporary building built and operational within two weeks. In the meantime, it opened for business in the parking lot of its demolished building. On June 20, The Home Depot opened a temporary building constructed by the company's disaster recovery team.
