The hypocenter

The wooden pole on center of the picture is the sign of hypocenter.
On the left side, The Nagasaki Prison Urakami Branch is on the hill.
The bridge in the right back is Matsuyama-bashi Bridge.
The makeshift shack of a food distribution center is in the left side of Matsuyama-bashi Bridge.
Because of having been exposed to the blast directly under the center of the explosion,telegraph poles and trees were charred and remained standing.
