The 1973 San Justo tornado was an extremely powerful F5 tornado which struck San Justo, a town in the province of Santa Fe, Argentina, on January 10, 1973. At least 63 people were reported dead and 350 were reported injured as it cut a 330-yard-wide (300 m) swath through the town. It was the most violent tornado ever recorded in South America, and also the entire Southern Hemisphere. This tornado was widely considered to have been an F5 on the Fujita Scale, and in 2017, it received its official F5 rating. The tornado had an economic cost of about $60,000 and was the deadliest tornado in Argentina's history.^[1]
