This article lists various tornado records. The most extreme tornado in recorded history was the Tri-State Tornado, which roared through parts of Missouri, Illinois, and Indiana on March 18, 1925. It is considered an F5, though tornadoes were not ranked on any scale in that era. It holds records for longest path length at 219 mi (352 km), longest duration at about 3.5 hours, and fastest forward speed for a significant tornado at 73 mph (117 km/h) anywhere on Earth. In addition, it is the deadliest single tornado in United States history (695 dead). It was also the second costliest tornado in history at the time, but has been surpassed by several others non-normalized. When costs are normalized for wealth and inflation, it still ranks third today.
The deadliest tornado in world history was the Daulatpur–Saturia tornado in Bangladesh on April 26, 1989, which killed approximately 1,300 people. Bangladesh has had at least 19 tornadoes in its history kill more than 100 people, almost half of the total for the rest of the world.
For 37 years, the most extensive tornado outbreak on record, in almost every category, was the Super Outbreak, which affected a large area of the central United States and extreme southern Ontario in Canada on April 3 and April 4, 1974. Not only did this outbreak feature an incredible 148 tornadoes in only 18 hours, but an unprecedented number of them were violent; 7 were of F5 intensity and 23 were F4. This outbreak had a staggering 16 tornadoes on the ground at the same time at the peak of the outbreak. More than 300 people, possibly as many as 330, were killed by tornadoes during this outbreak. However, this record was later broken during the April 25–28, 2011 tornado outbreak, which resulted in 355 tornadoes and 324 tornadic fatalities.
The April 25–28, 2011 tornado outbreak was the most prolific tornado outbreak in U.S. history. It produced 355 tornadoes, with 211 of those in a single 24-hour period on April 27, including 11 EF4 and 4 EF5 tornadoes. 348 deaths occurred in that outbreak, of which 324 were tornado related. The outbreak helped smash the record for most tornadoes in the month of April with 765 tornadoes, almost triple the prior record (267 in April 1974). The overall record for a single month was 542 in May 2003, which was also broken.
The infamous Super Outbreak of April 3–4, 1974, which spawned 148 confirmed tornadoes across eastern North America, held the record for the most prolific tornado outbreak for many years. Not only did it produce an exceptional number of tornadoes, but it was also an inordinately intense outbreak producing dozens of large, long-track tornadoes, including 7 F5 and 23 F4 tornadoes. More significant tornadoes occurred within 24 hours than any other week in the tornado record. Due to a secular trend in tornado reporting, the 2011 and 1974 tornado counts are not directly comparable.
