In particular the A-Dome as mentioned earlier, but also a surviving tree (1. 5km from the hypocentre transplanted in the park), the building that withstood the blast and the T-shaped bridge that was the actual orginal target.
He pointed out some of the other surviving buildings and structures, took us to a graveyard that survived (granite survived quite well) and the actual hypocentre of the bomb
The hypocentre site in Nagasaki, the Secretary-General said, "does far more than mark the geographic centre of the bomb" s impact.
Its destructive power was made worse because the point where the earth's crust began to rupture - its hypocentre - occurred at the relatively shallow depth of 13km (8.1 miles) beneath the surface.
The point of the earthquake's origin beneath the surface is called the hypocentre.
Then surface waves radiate outwards from the epicentre - the point on the surface directly above the hypocentre - and arrive after the main P and S waves.
