The Boston Molasses Flood is one of the most unusual disasters ever to occur. On January 15, 1919, in the North End of Boston, MA, a 2,300,000 gallon, 8,700 m3, molasses storage tank, owned by the Purity Distilling Company, exploded. In seconds, the tank emptied and a wave of molasses rushed through the streets at an estimated 35 mph, 56 km/h, killing 21 and injuring 150.
On that day the temperature rose above 40° F, 4.5 C and pressure built inside the tank. Rivets broke loose and shot out from the poorly constructed storage tank, unleashing a 40' wave of molasses. The elevated railroad tracks buckled and buildings were swept off their foundations and crushed. The city streets were flooded to a depth of 2' to 3'. People and horse were ensnared in the sticky molasses and could not escape. It took 300 people nearly two weeks to remove the molasses from the streets. Molasses remained in the harbor until summer.

A green plaque attached to a stone wall is inscribed:
Boston Molasses Flood
On January 15, 1919, a molasses tank at 529
Commercial Street exploded under pre-
ssure, killing 21 people. A 40-foot wave of
molasses buckled the elevated railroad tracks,
crushed buildings and inundated the neigh-
borhood. Structural defects in the tank com-
bined with unseasonably warm temperatures
contributed to the disaster.
