Ranked by confirmed fatalities. The single deadliest tornado in American history killed 695 people in three and a half hours across three states — an event no modern tornado has approached in death toll or path length.
The single deadliest tornado in US history. Traveled 219 miles across Missouri, Illinois, and Indiana over 3.5 hours at an average forward speed of 62 mph. Killed 234 in Murphysboro, IL alone — still the highest death toll from a tornado in any single American city. Read the full story →
Struck the port city of Natchez, Mississippi and tore down the Mississippi River, sinking flatboats and killing dozens of enslaved people whose deaths were not counted in the official toll of 317. Modern researchers believe the true death toll was substantially higher. The deadliest US tornado of the 19th century.
Struck densely populated urban St. Louis and crossed the Mississippi into East St. Louis, Illinois. Damaged the Eads Bridge and destroyed hundreds of homes and warehouses. The deadliest urban tornado in US history and the third-deadliest overall. In inflation-adjusted terms, one of the costliest tornadoes ever.
The 1936 Tupelo–Gainesville outbreak killed over 450 people across the Southeast in 48 hours. The Tupelo tornado struck at night, catching residents asleep, and destroyed 48 city blocks. A young Elvis Presley, then 15 months old, survived along with his family.
Struck the morning after the Tupelo event as part of the same 1936 outbreak. Two tornadoes merged over downtown Gainesville, destroying the Cooper Pants Factory where 70 workers died — one of the worst single-building tornado death tolls in US history.
The Glazier–Higgins–Woodward tornado family traveled roughly 100 miles across Texas, Oklahoma, and Kansas. In Woodward, Oklahoma, the tornado struck at night and destroyed over 100 city blocks. Led directly to the creation of the first US tornado forecasting program at Tinker Air Force Base.
The deadliest single US tornado since 1947 and the deadliest of the modern EF-scale era. Struck the city of Joplin (population ~50,000) with 200+ mph winds during evening hours, destroying more than 7,000 buildings including St. John's Regional Medical Center. Read the full story →
The Dixie Alley outbreak of 1908 produced this long-track killer that struck Amite, Louisiana and Purvis, Mississippi. Purvis was almost completely destroyed. Total 1908 outbreak deaths exceeded 320 across the Deep South — one of the deadliest 24-hour tornado periods in US history.
Struck the town of New Richmond (population 1,800) during a traveling circus performance, catching an unusually large crowd in the open. Half the town was destroyed. Remains the deadliest tornado in Wisconsin history.
Struck the Beecher neighborhood of Flint on the same day the Worcester, Massachusetts tornado struck (94 killed) — a rare double-city tornado disaster. Prior to Joplin, the Flint–Beecher tornado held the record as the deadliest US tornado of the second half of the 20th century, unmatched for 58 years.
The list is heavily weighted toward the pre-radar, pre-warning era. Only one tornado since 1955 — Joplin 2011 — makes the top 10. That is a testament to Doppler radar, watch-and-warning systems, storm chasers, and public safety education. In the 1920s, a violent tornado approaching a city was undetectable until it was visible; today, most receive 10 to 40 minutes of warning.
Deadliness is not the same as intensity. Some of the most powerful tornadoes ever measured — including the 1999 Bridge Creek–Moore F5 (301 mph) and the 2013 El Reno EF3 — killed relatively few people because they hit sparsely populated areas or occurred with strong warning. The deadliest tornadoes combine violent winds with dense population, poor warning, and vulnerable building stock.
