3 Deadliest Tornadoes in U.S. History

One of the deadliest tornadoes to ever hit the United States was the “Tri-State Tornado” that took over 695 lives and led to 2,027 injuries. It was called “Tri-State” because it devastated three states, namely, Indiana, Southern Missouri, and Illinois, on May 18th 1925. The enormous tornado spread across 219 miles, making it the most prolonged storm in United States history.

But that’s just for starters. Here’s a list of some of the most destructive tornadoes (other than the Tri-State Tornado) that occurred in the U.S., according to the National Centers for Environmental Information.

Great Natchez Tornado

The second deadliest tornado in U.S. history hit the states of Louisiana and Mississippi on May 6th 1840. It killed over 317 people and injured 109. The insured damages totaled up to over $32.3 million.

The Great St. Louis Tornado

This tornado was classified EF-4 on the Enhanced Fujita scale. It hit Missouri and Illinois on May 27th 1896, and killed at least 255 people. According to reports, the number of injuries was 1,000, and the insured damages totaled up to more than $700 million today.

In less than 30 minutes, the Great St. Louis Tornado spread across a 3-mile-wide path and wreaked havoc on the central and southern parts of the states with winds of up to 199 mph.
