Poland: The' Tallboy' or the 'earthquake' bomb exploded underwater in Poland. The biggest Second World War bomb ever found, Tallboy exploded as the navy divers tried to defuse it. However, no one was hurt as all of the divers were at a safe distance from the blast. They were trying to neutralise the bomb underwater by burning out its explosives. This process is known as deflagration.
The Second-Lieutenant Lewandowski said that the deflagration process turned into detonation, which means the action leading to the exploding of a bomb.
This WWII bomb was dropped by the Royal Air Force of Britain in the year 1945 in an attack on Lutzow, a German cruiser. The bomb weighed around 5,400 kg, including 2.400 of explosive.
It was discovered near the Piast Canal in northwest Poland, outside the town of Swinoujscie. The canal connects the Baltic Sea with the Oder River on Poland's border with Germany. More than 750 people were evacuated from the area where the bomb was found.
Although Swinoujscie has a liquefied natural gas (LNG) terminal, no one was injured and no property was damaged.
Designed by British aeronautical engineer Barnes Wallis, Tallboy was used to destroy assets through underground shocks.
It was found in 2019, beneath a waterway leading to the port of Szczecin while there was ongoing work to deepen the passage.
