areas affected=Missouri ,Illinois ,Indiana ,Kentucky ,Tennessee ,Alabama ,Kansas The Great Tri-State Tornado of Wednesday,
March 18 ,1925 , crossed from southeasternMissouri , through southernIllinois , then into southwesternIndiana , and was the deadliesttornado inU.S. history . With 695 confirmed fatalities, the tornado killed more than twice as many as the second deadliest, the 1840Great Natchez Tornado . The continuous ≥219 mile (≥352 km) track left by the tornado was the longest ever recorded in the world. It is recognized as an F5 tornado, the maximal damage rating issued on theFujita scale .cite book |last = Grazulis |first = Thomas P. |authorlink = Thomas P.

The tornado was part of a larger
tornado outbreak with several other destructive tornadoes inTennessee ,Kentucky , and Indiana, as well as tornadoes inAlabama andKansas . Including additional tornadoes that day, at least 747 were killed and 2,298 were injured during this unusually intense and early spring outbreak. There were undoubtedly many other smaller tornadoes that have been lost to history.Tri-State Tornado
One tornado or a series?
There has long been discussion as to whether the event was a single continuous tornado or a
tornado family . Quality of data because of distance in the past and lack of other tornadoes approaching this path length and duration raised doubts; and theory on tornadoes andsupercell morphology suggested such duration was exceedingly improbable. In fact, several other historically very long track tornadoes were subsequently found to be tornado families, although in the last several years some very long track tornadoes and supercells have occurred. Thorough new and continuing research, however, has found no break in the path and also that the tornado touchdown occurred approximately 15 miles (24 km) before previously thought, bringing the total path length to around 234 mi (377 km).cite web |last = Doswell |first = Charles A., III |authorlink = Charles A.

The vortex was first sighted around 1:01 p.m., north-north-west of
Ellington, Missouri . The tornado sped to the northeast, killing two and causing $500,000 worth of property damage and the near annihilation of Annapolis, then struck the mining town of Leadanna. In Bollinger County, 32 children were injured when two schools were damaged. Redford, Cornwall, Biehle, and Frohna also were hit by the tornado. At least eleven died altogether in Missouri.Illinois
The tornado crossed the
Mississippi River intosouthern Illinois , hitting the town of Gorham, at 2:30 p.m., essentially obliterating the entire town, killing 34. Continuing to the northeast at an average speed of 62 miles per hour (100 km/h) (and up to 73 miles per hour [117 km/h] ), the tornado cut a swath almost a mile (1.6 km) wide through Murphysboro, De Soto, Hurst-Bush, and West Frankfort. Also afflicted were Zeigler, Eighteen, and Crossville. Within 40 minutes, 541 lives were lost and 1,423 were seriously injured. The village of Parrish was completely destroyed, killing 22. In Murphysboro, 234 were killed, the most in a single city in U.S. history. The tornado proceeded to decimate rural areas across Hamilton and White Counties, claiming 65 more residents. In Illinois, at least 613 were killed, the most in a single state in U.S. history.Indiana
Crossing the
Wabash River into Indiana, the tornado struck and nearly totally demolished Griffin, devastated rural areas, impacted Owensville, then roared into Princeton, destroying half the town. The tornado traveled ten more miles (16 km) to the northeast before finally dissipating at about 4:30 p.m. around three miles (5 km) southwest of Petersburg. In Indiana, at least 71 perished.Toll
In all, at least 695 died and 2027 were injured, mostly in southern Illinois. Three states, thirteen counties, and more than nineteen communities, four of which were essentially effaced (several of these and others never recovered), were in the path of the record 3.5 hour duration tornado. Total damage was estimated at $16.5 million; adjusted for wealth and inflation the toll is approximately $1.4 billion (1997
USD ), surpassed in history only by two extremely destructive tornadoes in the City of St. Louis.cite journal |last = Brooks |first = Harold E. |authorlink = Harold E. Brooks |coauthors = C.A. Doswell |title = Normalized Damage from Major Tornadoes in the United States: 1890–1999 |journal =Weather and Forecasting |volume = 16 |issue = 1 |pages = 168–76 |publisher =American Meteorological Society |month = February | url = http://ams.allenpress.com/perlserv/?request=get-abstract&doi=10.1175%2F1520-0434(2001)016%3C0168%3ANDFMTI%3E2.0.CO%3B2 |doi = 10.1175/1520-0434(2001)016<0168:NDFMTI>2.0.CO;2 |year = 2001 ] These three events in terms of destruction, inferred by normalized monetary losses, are by far the most destructive (and expensive) tornadoes ever in the United States. Over 15,000 homes were destroyed by the Tri-State Tornado.Nine schools across three states were destroyed in which 69 students were killed, more schools destroyed and more students killed (as well as the single school record of 33 deaths in De Soto, Illinois) than any other tornado in U.S. history.
The unusual appearance (due to its size) of the very fast moving tornado, best described by the witnesses along most of its path as an amorphous rolling fog or boiling clouds on the ground, fooled normally weather wise farm owners (and people in general) who did not sense the danger until the storm was upon them.
The tornado was accompanied by extreme
downburst winds generally throughout the entirety of its course; the tornado and accompanying downbursts increased the width of damage from an average of 3/4-mile (1.2 km) (though at times over a mile [1.6 km] wide) to an area three miles (5 km) wide at times.In addition to the dead and injured, thousands were left without shelter or food. Fires erupted, exacerbating the damage. Looting and theft, notably of the property of the dead, was reported. Recovery was generally slow with the event leaving a lasting blow to the region.
