Revelation 16:18-20
16:18 Then there were flashes of lightning, roaring, and crashes of thunder, and there was a tremendous earthquake – an earthquake unequaled since humanity has been on the earth, so tremendous was that earthquake.
16:19 The great city was split into three parts and the cities of the nations collapsed. So Babylon the great was remembered before God, and was given the cup filled with the wine made of God’s furious wrath.
16:20 Every island fled away and no mountains could be found.
