The mine came down between the tram and tenement at the corner of Centre Street, killing 110 people and injuring a further 118.
The blast was so powerful that among those killed were three French sailors on the Broomielaw, on the other side of the river.
Incredibly, 20 people were rescued alive from the wreckage of the tram.
Speaking after the incident, Head Warden E. Jones, said: "It should be placed on record the splendid manner in which the civilians of Tradeston came forward... and rendered assistance with total disregard to danger. They were really splendid."
