Near Keany Square, at 529 Commercial Street, a huge molasses tank 50 ft (15 m) tall, 90 ft (27 m) in diameter and containing as much as 2300000 US gal (8,706.4 m³) collapsed. Witnesses stated that as it collapsed, there was a loud rumbling sound, like a machine gun as the rivet

s shot out of the tank, and that the ground shook as if a train were passing by.

The collapse unleashed an immense wave of molasses between 8 and 15 ft (2.5 and 4.5 m) high, moving at 35 mph (56 km/h), and exerting a pressure of 2 ton/ft² (200 kPa). The molasses wave was of sufficient force to break the girders of the adjacent Boston Elevated Railway

 off the tracks. Nearby, buildings were swept off their foundations and crushed. Several blocks were flooded to a depth of 2 to 3 ft (61 to 91.4 cm). As described by author Stephen Puleo:
Molasses, waist deep, covered the street and swirled and bubbled about the wreckage. Here and there struggled a form — whether it was animal or human being was impossible to tell. Only an upheaval, a thrashing about in the sticky mass, showed where any life was... Horses died like so many flies on sticky fly-paper. The more they struggled, the deeper in the mess they were ensnared. Human beings — men and women — suffered likewise.

Anthony di Stasio, walking homeward with his sisters from the Michelangelo School, was picked up by the wave and carried, tumbling on its crest, almost as though he were surfing. Then he grounded and the molasses rolled him like a pebble as the wave diminished. He heard his mother call his name and couldn't answer, his throat was so clogged with the smothering goo. He passed out, then opened his eyes to find three of his sisters staring at him.

Aftermath

First to the scene were 116 cadets under the direction of Lieutenant Commander H. J. Copeland from USS Nantucket, a training ship of the Massachusetts Nautical School (which is now the Massachusetts Maritime Academy

), that was docked nearby at the playground pier. They ran several blocks toward the accident. They worked to keep the curious from getting in the way of the rescuers while others entered into the knee-deep sticky mess to pull out the survivors. Soon the Boston Police, Red Cross, Army and other Navy personnel arrived. Some nurses from the Red Cross dove into the molasses, while others tended to the wounded, keeping them warm as well as keeping the exhausted workers fed. Many of these people worked through the night. The injured were so numerous that doctors and surgeons set up a makeshift hospital in a nearby building. Rescuers found it difficult to make their way through the syrup to help the victims. It took four days before they stopped searching for victims; many dead were so glazed over in molasses, they were hard to recognize.

Several factors that occurred on that day and the previous days might have contributed to the disaster. The tank was constructed poorly and tested insufficiently. Due to fermentation

 production might have raised the internal pressure. The rise in local temperatures that occurred over the previous day also would have assisted in building this pressure. Records show that the air temperature rose from 2°F to 41°F (from −17°C to 5°C) over that period. The failure occurred from a manhole cover near the base of the tank, and it is possible that a fatigue

 is greatest near the base of a filled cylindrical tank. The tank had only been filled to capacity eight times since it was built a few years previously, putting the walls under an intermittent, cyclical load.

An inquiry after the disaster revealed that Arthur Jell, who oversaw the construction, neglected basic safety tests, such as filling the tank with water to check for leaks. When filled with molasses, the tank leaked so badly that it was painted brown to hide the leaks. Local residents collected leaked molasses for their homes.

While an urban legend, a 1999 television documentary, part of the Modern Marvels' Engineering Disasters sub-series, argued that—even if there was no specific plan to make alcohol to beat Prohibition—there may have been some general idea of increasing the volume at the last minute so as to prepare in case alcohol prohibition might occur.

 courts. Immediately to the east is the larger Puopolo Park, with additional recreational facilities.

A small plaque at the entrance to Puopolo Park, placed by the Bostonian Society, commemorates the disaster. The plaque, entitled "Boston Molasses Flood", reads:
On January 15, 1919, a molasses tank at 529 Commercial Street exploded under pressure, killing 21 people. A 40-foot wave of molasses buckled the elevated railroad tracks, crushed buildings and inundated the neighborhood. Structural defects in the tank combined with unseasonably warm temperatures contributed to the disaster.


Drivers on Boston's Old Town Trolley and other tour services often read off accounts of the accident to their passengers, sometimes referring to it by the neologism "The Boston Molassacre".
