In 1919, the Great Molasses Flood occurred in which city?
And the answer: Boston.
The Great Molasses Flood of 1919 occurred in the American city of Boston, Massachusetts. Filled with over two million gallons of molasses, a large storage tank burst, and a 15-foot wave of the thick sticky substance poured through the streets at an estimated 35 mph. Twenty-one people didn't survive, and another 150 were injured.
Looking down the barrel of impending prohibition, the United States Industrial Alcohol company was in a rush to turn the sweet sugary molasses into booze as quickly as possible. As a result, the 2.3 million gallon tank of molasses was filled to the brim – and then some. Around midday on January 15, 1919, after days of the customary creaks and groans of the giant tank, the molasses let out a roar as a devastating flood of the sweet sticky substance exploded out of the tank and down Commercial Street. Buildings were instantly swept off their foundations, cars were squashed, even a railroad car was turned off its tracks.
In the wake of the disaster, the victims filed 119 different lawsuits against United States Industrial Alcohol. In a long-drawn out case, in which the Industrial Alcohol Company cited sabotage by Italian anarchist groups, USIA finally paid the flood victims and their family members $628,000 in damages (the equivalent of around $8 million today). Meanwhile, the streets of downtown Boston and its waters remained brown for months. Some even claimed to smell the sweet molasses for years following the flood.
