One of the first major explosions was around the Johnson Barge No. 17, which contained 50 tons of TNT. The explosion created a detonation wave that traveled at 7.5km per second. Fragments from the explosion traveled long distances, some lodging in the Statue of Liberty and some in the clock tower of The Jersey Journal building in Journal Square.

Windows were broken as far as 40 km away, including thousands in Lower Manhattan. Some window panes in Times Square were shattered. The stained glass windows in St. Patrick’s Church were destroyed. The outer wall of Jersey City’s City Hall was cracked and the Brooklyn Bridge was shaken.
