695 Lives Lost: The Worst Tornado In US History Marks 100 Years

Few Americans today remember the name of the deadliest tornado in US history.

More than a century has passed since the devastating Tri-State tornado tore through the country without warning, claiming 695 lives, destroying thousands of homes, and wiping out entire towns in just 3.5 hours (per the Evansville Museum of Arts).

Surprisingly, the deadliest tornado in American history wasn’t part of a typical storm system. A single, relentless twister carved a destructive path across three states. To this day, experts debate whether the Tri-State tornado was one continuous storm or a series of violent tornadoes.

Despite its catastrophic impact, the 100th anniversary of the Tri-State tornado passed with little recognition, a sign that this historic disaster has faded from national memory.

On March 18, 1925, an ordinary day turned catastrophic across Southeastern Missouri, Southern Illinois, and Southwestern Indiana.

The deadly tornado first touched down near Ellington, Missouri, killing eight people. It then tore across the Mississippi River and the length of Southern Illinois, leaving a historic trail of devastation in its wake.

In rural communities, residents had no warning. There were no sirens or alerts, only ominous skies and rapidly intensifying winds. The tornado struck too suddenly and with such force that people had no chance to prepare or escape.

The Tri-State tornado carved a 219-mile path of havoc, which is still the longest ever recorded by a tornado (per ABC7 Chicago).

Hundreds died that day, including over 230 people in Murphysboro and about 150 in West Frankfort. The tragedy also claimed 33 schoolchildren at De Soto School in Illinois.

The tornado was so powerful that it obliterated entire towns, such as Biehle, Missouri; Gorham, Illinois; and Griffin, Indiana (per BBC).

Eyewitness accounts of the century-old disaster are understandably rare. But, despite the wealth of archival photos and press clippings, few reached national circulation.

This scarcity becomes especially clear when searching for newspapers from that time. Only a handful of images surface, often preserved by niche archival sites like Timothy Hughes Rare Newspapers.

Still, some survivors shared their stories decades later. One such voice is Ms. Lela Hartman, who recounted the tornado in Lecture 8 of Introduction to Energy and Environment: Life Under the Pale Sun from the UW School of Oceanography.

On December 30, 1999, Hartman recalled the day the tornado struck while visiting her grandmother’s farm, about three miles west of West Frankfort, Illinois.

Hartman, a lifelong resident of Benton, Illinois, was just 4 years old in 1925, but she vividly remembered the horror. “I was quite young when that happened, but I remember it well. I remember it.”

She described the weather turning ominous: “As the day went on, it started lookin’ like rain, and cloudin’ up, and gettin’ dark… my dad said, ‘You know, we’d better go to the cellar!’”

“It just kept gettin’ darker and darker… it was almost as black as night when we finally went to the cellar.”

She recalled hearing strange noises from inside: “We could hear things that you didn’t hear in an ordinary storm.”

When she emerged, the destruction was overwhelming. A tree had blown across the cellar door. Their car, now topless, had been tossed near the barnyard fence. A massive oak tree had been split clean through.

Hartman remembered a nearby house reduced to its foundation and noted how locals had long referred to the storm as a “cyclone,” not a tornado.

Further recollections appeared in the St. Louis Post-Dispatch, republished in a 2000 article by American Heritage.

May Williams, a mission worker in Murphysboro, described the terror inside Moose Hall as the tornado hit: “We were being showered with glass, stones, trash, bricks, and anything… You could see shapes hurtling over us in the air.”

After the storm passed, she wrote, “We walked the city… People went about almost without clothes, with no shoes on, wrapped in rugs or blankets… everything was on fire… We were black from head to foot.”

The emotional toll endured long after. Survivors marked time by the event, referring to life as “before” or “after” the storm.

The Tri-State tornado remains the deadliest and longest-tracked tornado in US history. No modern storm comes close: 695 lives lost, 2,027 people injured, 13 counties devastated, and 15,000 homes destroyed.

In 1925, the storm caused $16.5 million in damage, equivalent to nearly $3 billion today.

Experts believe the tornado reached F5 strength on the Fujita scale, which rates tornadoes based on estimated wind speeds and associated damage (per the National Weather Service).

Although rating systems have changed, meteorologists widely agree that the Tri-State tornado, with wind speeds estimated between 261 and 318 mph, was an exceptionally powerful natural event.

Emergency response was swift. Medical teams arrived quickly, and fire departments deployed vital equipment.

Injured survivors were transported by train to Chicago, though care conditions were far from ideal. Medical teams worked through the night using kerosene lamps, candles, and lanterns for light.

Critical medical supplies like morphine, anesthetics, and antitetanus ran out at the worst time. Trainloads of coffins and flowers soon arrived from Chicago and St. Louis.

Unlike modern tornadoes, the Tri-State tornado offered no chance to outrun it. It advanced with extraordinary speed, immense width, and relentless intensity.

What made it so powerful?

Experts continue to debate its classification and underlying conditions. A team of eight severe storm meteorologists concluded that no single factor fully explains the tornado’s extreme behavior (per NSSL, NOAA National Severe Storms Laboratory).

Several atmospheric features likely played a role. One theory points to a “supercharged” jet stream, which can amplify weather systems (per NOAA SciJinks).

Another possible contributor is thermal inversion, where a warm air layer traps cooler air below, potentially triggering unstable and severe conditions (per Airly).

The catastrophic Tri-State tornado prompted long-overdue reforms in US storm tracking systems and public preparedness.

Though gradual, these changes ultimately led to significant advancements. Today, meteorologists rely on real-time satellite data, computer models, weather balloons, and Doppler radar to deliver far more accurate storm forecasts (per MPR News).

Tornado sirens, emergency alerts, and smartphones offer vital early warnings during severe weather.

Thanks to the work of the National Weather Service and the Storm Prediction Center, extreme weather forecasts can now be issued up to two days in advance.

Local storm spotters also play a crucial role, reporting firsthand observations that help meteorologists confirm and respond to dangerous tornadoes, which could have saved hundreds of lives in 1925.

Even now, more than 100 years later, researchers continue to study the 1925 tornado for insights. A detailed analysis, “Meteorological Analyses of the Tri-State Tornado Event of March 1925,” remains a key reference in The Electronic Journal of Severe Storms Meteorology.

Despite its significance, the Tri-State tornado’s centennial passed with little public notice. Its legacy endures more in scientific literature than in national memory.
