Whats The Worst Tornado In History?

by
Last updated on 6 min read

The worst tornado in history was the Daulatpur–Saturia tornado in Bangladesh (April 26, 1989), which killed an estimated 1,300 people. The deadliest in the United States remains the Tri-State Tornado (March 18, 1925), killing 695.

What was the strongest tornado in history?

The strongest tornado on record was the Bridge Creek–Moore tornado (May 3, 1999) with winds reaching 302 mph. It occurred during the 1999 Oklahoma tornado outbreak and caused catastrophic damage.

Now, the Enhanced Fujita (EF) scale—used since 2007—rates tornadoes based on damage rather than direct wind measurement. While wind speeds over 300 mph are theoretically possible, most extreme tornadoes exceed 200 mph, classifying them as EF5. Honestly, this is the best approach we’ve got for measuring these monsters. The Bridge Creek–Moore tornado still holds the record for the highest wind speed ever recorded NOAA Storm Events Database.

What are the 5 worst tornadoes?

The five deadliest tornadoes in recorded history are the Daulatpur–Saturia (1989, Bangladesh), Tri-State (1925, USA), Great Natchez (1840, USA), St. Louis (1896, USA), and Tupelo (1936, USA).

These disasters left thousands dead across some of the most populated regions of their time. The Daulatpur–Saturia tornado remains the deadliest globally, while the Tri-State tornado still holds the record for the deadliest in U.S. history. Funny enough, all of these happened before we had modern warning systems NOAA National Centers for Environmental Information.

What is the most deaths from a tornado?

The deadliest single tornado killed 695 people during the Tri-State Tornado (March 18, 1925). It traveled 219 miles across Missouri, Illinois, and Indiana.

RankDateInjuriesDeaths
1March 18, 19252,027695
2May 6, 1840109317
3May 27, 18961,000255
4April 5, 1936700216

Here’s the thing: recent outbreaks, like the 2011 Super Outbreak, have caused high fatalities not because of a single storm but because of clustered events. That’s why we see such staggering numbers in a short time NOAA Storm Prediction Center.

Has there ever been a F6 tornado?

There has never been an officially recorded F6 tornado. The Enhanced Fujita scale tops out at EF5 (winds over 200 mph).

Dr. Ted Fujita proposed an F6 rating back in 1971, but it never caught on. Even if winds exceeded 200 mph, damage indicators wouldn’t support a higher rating under the EF scale. The scale is designed to reflect what we actually see on the ground NOAA EF Scale Guide.

Are F5 tornadoes rare?

Since 1950, there have been 58 officially rated F5 or EF5 tornadoes in the U.S. That averages to about one per year, though they often occur in clusters.

The 2011 Super Outbreak alone produced four EF5 tornadoes in a single day. Some years pass without any, while others see multiple. Improved construction and warning systems have reduced fatalities, but violent tornadoes remain unpredictable as heck NOAA Storm Prediction Center FAQ.

Where is Tornado Alley located?

Tornado Alley spans from central Texas northward to northern Iowa, and from central Kansas and Nebraska east to western Ohio. Its boundaries vary depending on frequency, intensity, or events per unit area.

This region’s perfect storm of geography—flat terrain, warm moist air from the Gulf, and cool dry air from Canada—creates ideal conditions for tornado formation. Some researchers also include parts of the Deep South in "Dixie Alley," where tornadoes can be just as intense NOAA National Severe Storms Laboratory.

Which country gets the most tornadoes?

The United States experiences more tornadoes than any other country. Canada ranks second, followed by Bangladesh and parts of Europe.

The U.S. averages over 1,200 tornadoes annually, with the highest concentration in Tornado Alley. Bangladesh gets hit hard too, thanks to high population density and vulnerable infrastructure. European tornadoes are less frequent but still pack a punch NOAA Global Events Database.

Which state has the deadliest tornadoes?

Missouri has recorded the highest number of tornado-related fatalities over time. The Tri-State Tornado (1925) alone killed 695 people across three states.

Other high-risk states include Alabama, Oklahoma, and Illinois. Fatalities often correlate with population density and building vulnerability. Improved forecasts and public awareness have reduced deaths in recent decades, but tornadoes remain a serious threat NOAA Weather Service.

Can you survive an EF5 tornado?

Survival is possible but extremely difficult in an EF5 tornado. Wind speeds over 200 mph can destroy even well-built homes.

Experts recommend underground shelters or specially designed safe rooms. Mobile homes? Forget about it. While some structures have survived EF5 winds, the risk of injury or death remains sky-high FEMA Tornado Preparedness.

Why do tornadoes never hit big cities?

Tornadoes can and do hit big cities—it’s just statistically less likely due to their small size. Urban areas cover only about 3% of the U.S. landmass.

Recent examples include the 2011 Joplin, Missouri EF5 and the 2020 Nashville, Tennessee EF3. Cities like Dallas, Oklahoma City, and Atlanta have all experienced direct tornado strikes. Urban heat islands and buildings can influence storm behavior, but tornadoes don’t "avoid" cities—it’s just bad luck when they do hit NOAA Tornado Myths.

Can you fly over a tornado?

Commercial flights are never directed to fly over tornadoes. Air traffic control reroutes aircraft to avoid severe weather entirely.

Tornadoes produce extreme turbulence, hail, and lightning that can damage aircraft. Pilots and controllers prioritize safety, often diverting flights hundreds of miles away. Smaller aircraft should also avoid storms due to unpredictable wind shear and downdrafts—no one wants to get caught in that mess FAA Pilot Safety Brochure.

What is the fastest tornado on Earth?

The fastest wind speed in a tornado was 302 mph, recorded in the Bridge Creek–Moore tornado (May 3, 1999). This remains the highest wind speed ever measured in a tornado.

Record ValueDate of EventLength of RecordGeospatial Location
135 m/s (302 mph)May 3, 1999~1996–presentBridge Creek, Oklahoma [35°14’N, 97°44’W, elevation 416 m]

This measurement came from mobile Doppler radar. For most historical tornadoes, wind speeds are estimated based on damage patterns—we weren’t exactly standing in the middle of them with anemometers NOAA National Severe Storms Laboratory.

How much damage would a F12 tornado do?

A hypothetical F12 tornado (winds over 318 mph) would cause total destruction of buildings and infrastructure. Winds this extreme would lift entire structures off foundations.

EF RatingDegree of Damage DescriptionApproximate Wind Speed (mph)
EF5Total destruction of entire buildingOver 200
EF4Severe damage; well-built houses destroyed166–200
EF3Roofs torn off, trains overturned136–165

No F12 tornado has ever been recorded. The EF scale caps at EF5 because the damage from winds over 200 mph is already catastrophic. An F12 would make everything we’ve seen look like a minor thunderstorm NOAA EF Scale Guide.

What was the first ever tornado?

The first documented tornado in the United States occurred on July 5, 1643, in Lynn, Newbury, and Hampton, Massachusetts. It was recorded by colonial settlers.

Early records are sparse, but this event is widely cited in historical accounts. Tornadoes likely occurred long before, but written documentation was rare. The 1643 event is considered the earliest verifiable account we’ve got NOAA Weather Service Historical Records.

What are the 5 levels of a tornado?

Tornadoes are rated on the Enhanced Fujita Scale (EF0–EF5) based on damage and wind speed.

EF RatingWind Speed (mph)Damage Description
EF065–85Light damage; broken branches
EF186–110Moderate damage; roof shingles torn
EF2111–135Considerable damage; mobile homes destroyed
EF3136–165Severe damage; trains overturned
EF4166–200Devastating damage; houses leveled
EF5Over 200Total destruction; swept clean

The EF scale replaced the original F-scale in 2007 because the old system was too subjective. Now, trained meteorologists assign ratings after damage surveys, which gives us a much clearer picture of a tornado’s power NOAA EF Scale Guide.
