1975 Omaha tornado outbreak
Three people were killed and 133 reported injured. One of the fatalities was thrown by the tornado from her home to a backyard four or five houses away. Debris was found miles away. Over 4,000 buildings were damaged and 287 were destroyed. In terms of damage, it was the costliest tornado in American history to that date, with damages costing at least $250 million to $300 million (around $1.7 billion in 2015 dollars), and insurance costs estimated at up to $1.1 billion (in 1975). It was the third-costliest tornado, behind the Oklahoma City-area F5 tornado on May 3, 1999, and the Wichita Falls, Texas, tornadoes on April 10, 1979, until the Joplin, Missouri EF5 tornado on May 22, 2011. It is now currently the seventh-costliest tornado on record.
Tri-State Tornado
In all, at least 695 people died and 2,027 were injured, the majority in southern Illinois. Three states, 13 counties, and more than 19 communities, four of which were effectively effaced (several of these and other rural areas never recovered), were in the path of the record 3.5 hour duration tornado. Approximately 15,000 homes were destroyed by the Tri-State Tornado. Total damage was estimated at $16.5 million; adjusted for increases population/wealth and inflation the toll is approximately $1.4 billion (1997 USD), surpassed in history (through 2010) only by two extremely destructive tornadoes in the City of St. Louis in 1896 and 1927.
