Tornado outbreak sequence of May 21–26, 2011
The tornado outbreak sequence of May 21–26, 2011 was one of the largest tornado outbreaks on record which affected the Midwestern and Southern regions of the United States. Most of the tornadoes developed in a corridor from Lake Superior southwest to central Texas; isolated tornadoes occurred in other areas. An especially destructive tornado destroyed one-third of Joplin, Missouri, resulting in 158 deaths and over 1,000 injuries. The Joplin tornado is the deadliest in the U.S. since April 9, 1947, when an intense tornado killed 181 in the Woodward, Oklahoma area. Tornado-related deaths also occurred in Arkansas, Kansas, Minnesota, and Oklahoma. Overall, the tornado outbreak resulted in 184 deaths, 6 of those non-tornadic, making it second only to the 2011 Super Outbreak as the deadliest since 1974, and the second costliest tornado outbreak in U.S. history behind that same April 2011 outbreak, with insured damage estimated at $4–7 billion.

The catastrophe and risk modeling firm Eqecat, Inc. has estimated the damage at one billion to three billion USD, but noted that the true damage is not yet known, since the firm does not have access to data on uninsured losses. More than 19,000 insurance claims had been filed by mid-June. The impact on the insurance industry is not so much the number of claims, but the cumulative effect of such a large number of total losses. More than 2500 local people employed in insurance have been involved in some capacity. It is assumed that State Farm will assume the largest share of these losses, having market share of 27% for homeowners insurance and 21% for automobile insurance.
