The force of the explosion was immense, and heavy debris was thrown as much as from the seat of the explosion. Huge granite blocks forming the tramway for carts outside the warehouse were flung over the church for two and three hundred yards into neighbouring streets and buildings. One is recorded as falling away through the roof of the Grey Horse pub. A stone of weight damaged property in Oakwellgate. Large blocks of wood and stone were projected widely over Newcastle, reaching the west end of the quayside. The "Courant" newspaper office in Pilgrim Street was hit. A stone weighing fell through the roof of an opticians in Grey Street; when workmen discovered it in the morning it was still too hot to touch. A huge beam of timber, six feet long, was found on the roof of All Saint's Church. Another, ten feet in length and weighing 3 cwt (150 kg) landed on the Ridley Arms in Pilgrim Street; and others on the roof of a house in Moseley Street.
