The nation’s two longest and most deadly tornadoes occurred in Illinois early in the 20th Century. One crossed central Illinois in 1917 and killed 211 persons while the other crossed southern Illinois in 1925 and killed 695, the nation’s greatest loss of life from a tornado. These were the greatest natural disasters ever in Illinois. The 1917 tornado cov-ered 293 miles and the 1925 storm covered 219 miles, both national records. Property damages in 1917 totaled $51.5 million (2008 dollars) and those in 1925 were $134.2 mil-lion (2008 dollars).
