General view of Nagasaki taken from about four miles southeast of X. The chimneys in the 'background, are lo­ cated at the Mitsubishi Steel and Arms Works. The hills in the right foreground shielded a large part of the

business and residential section from the full effects of the bomb blast. This view shows typical Japanese resi­ dential construction, consisting of light frame houses with tile roofs, and shows how the hillsldeB are cultivated

and inhabited almost to the tops.

Figure 14

Pre-strike aerial view of Nagasaki. X is Just northeast of the stadium which is visi­ ble in the upper right portion of the photograph. The main targets were the Mitsubishi-

Urakami Ordnance Works (Torpedo Works) in the upper righthand corner of the picture, and

the Mitsubishi Steel and Arms Works, which is spread out along the east bank of the Urakami

River, in the central part of the picture. Note how the industrial valley is inclosed by

steep hills which tended to shield the main business and residential portion of the city

(righthand portion of the picture) from the full effects of the blast. Fire lanes effected

by the Japanese are also visible.

Figure l6

General panoramic view taken from the Nagasaki Medical School and Hospital, looking southeast. In the fore­ ground, at the foot of the hill on which the Medical School is located, the double-track street railway loop to

the hospital buildings will be noticed. There was practically no damage to the tracks themselves, but the trolley

wires were knocked down and the tracks covered with debris. The whole area shown in this picture was covered with

industrial buildings and small residences almost as close together as it was possible to build them. In the back­ ground, the skeleton remains of the Mitsubishi Steel and Arms Works can be seen. Note that the reinforced concrete

office buildings still stand amid the wreckage of steel frame buildings. In the reinforced concrete school build­ ings at the foot of the hills in the background, the doors, windows, ceiling, and building contents were damaged by

the blast.

View of the Military Area in Hiroshima. This view shows the almost complete destruction of

ordnance, storage, and administrative "buildings located in the northeast section of the military area.

Figure IS Post-strike aerial view of Hiroshima after the Bomb,

Aerial view looking directly down on X in Hiroshima, showing the target area completely leveled

except for reinforced concrete "building frames. Roofs and intermediate floors collapsed on five of

these buildings leaving the exterior walls partially standing. The dark spots on the roofs of other

"buildings are depressions formed "by the downward distortion of the roof structure.

Figure 26

Commercial Museum 700 feet west of X in Hiroshima. The steel tower in the foreground collapsed in the

direction of the blast. The monuments in the cemetery were not overturned "because the "blast pressure was

largely downward in this area.


Figure 27

Typical reinforced concrete "building 1000 feet northwest of X. The concrete roof slat was supported "by

concrete beams with no interior columns. The interior beams failed, causing the roof slab to settle as

shown. The entire parapet wall was demolished, one section resting on the road, having blown in the

direction of the blast.

Figure 28

Bridge, 1000 feet northwest of X in Hiroshima. The "blast pressure at this point nad a considerable

vertical component. Along the center and left side of the bridge, the concrete girders supporting the

floor slat did not fall; hovever, to the right of the center, girders under several spans failed, causing

considerable settlement in the floor slab. One depression can be seen in the right foreground of this

Looking east from the Red Cross Hospital, 0.9 mile south of X. The reinforced concrete Communications Bureau

building in the right foreground is one mile from X. Damages to the building were not extensive and were similar

to those at the Red Cross Hospital. The two standing walls in the center background are parallel to the direction

of the blast. The framework of two gas-holders may be seen in the center background 1.2 miles from X. The crownB

of the holders were dished down and torn open. The buildings of the Commercial Gas-works were seriously damaged.

Large building seen on the right of the gas-works w"fl farther back are part of the Army Clothing Depot. The

burned out area extends to the river in the background.

structurally. Other buildings in this group were of wooden construction and were destroyed "by blast

and fire. The buildings still standing were gutted by fires of secondary origin. The end walls of

two otherwise demolished buildings may be seen in the center background; these walls are parallel with

the direction of the blast which was from left to right.

Aerial view of the Mitsutiahi Steel and Arms Works in Nagasaki, from 0.3 to 1.2 miles south of X.

This view looking north toward X shows that the middle three-fourths of the atove plant with the

damage caused by the atomic bomb. The long buildings in the south (between reinforced concrete offices)

are concrete arch-roof structures that collapsed. The buildings on the west bank of the river are the

remains of the Mitsubishi Steel Casting Plant.

Figure k6

Panorama of Nagasaki. This aerial view shows the devastation north of X and west of the Urakami

River. All of the heavily "built-up areas were completely destroyed, and dwellings were seriously

damaged almost to the tops of the hills. The large reinforced concrete "building remaining in the left

center of the picture is the Shiroyama School. The south wing facing X was "badly wrecked.

Panorama showing the general destruction in the industrial valley of Nagasaki, looking west from

the Medical School and Hospital toward the reinforced concrete factory training school at the foot of

the hills in the background. The north end of the Mitsubishi Steel and Arms Works can be seen in the

middle portion of the picture. The reinforced concrete chimney, though still vertical, was cracked by

the blast. This area was covered with factories and homes. The tracks of the street railway trolley

were covered with debris, but were not otherwise much damaged.

The Nagasaki Medical School and Hospital, from O.k to 0.55 mile southeast of X. This view

shows one of the court yards, and several of the buildings of modern construction. The first

building on the left (far end - second story) vas hit by a bomb eight days before the atomic

bomb hit Nagasaki.

This view shows the damage to the

Figure 55

Reinforced concrete school building, 0.3 mile southwest of X. This building was used as a factory training

school. The damage on the left end resulted from a parapet wall pulling loose. Damage on the right end was

caused by failure of wall columns which permitted collapse of structural steel roof trusses.

Figure 60

A view of one of the factory buildings with saw-tooth roof truss in the Mitsubishi-Urakami

Ordnance Works, 0.9 mile from X. These trusses were very lightly constructed of light steel members.

The roof failed from the thrust of the bomb blast, and its failure collapsed the purlins and caused

the roof to fall in generally.

A shop "building approximately 0.9 miles from X, in the Mitsubishi-Urakami Ordnance Works. This

"building vas a total loss. The extremely light steel construction and the extensive use of wood com­ "bined to form a very weak "building.

Figure 62

Interior view of one of the machine shops in the Mitsubishi-Urakami Ordnance Works, approximately

0.9 miles from X. The siding and roofing was stripped away by the "blast. The reinforced concrete

Pill-Boxes in this building (aisle in center of picture) indicates that prison labor was used here.

Figure 63

Wooden building 1.5 miles northeast of X in Nagasaki.

Figure 6k

Small reinforced concrete chimney, 0.25 mile north of X. This chimney was knocked over approximately 15-feet

above the taBe. The chimney was k.3 feet in diameter and 65-feet high. The walla were 6-inchee thick and the

reinforcing consisted of 5/l6-inch round bars spaced on 6^-inch centers. The horizontal reinforcing was 1/8-Inch

round bars with an 8-inch spacing. The chimney was unllned.

Figure 65

Reinforced concrete bridge, 0.50 mile north of X in Nagasaki. This bridge consisted of a reinforced con­ crete T-"beam deck with concrete abutments and piers. The three spans are approximately 35 feet long each.

Failure of the west span resulted when the deck was knocked off the pier and abutment by the force of the blast

from the south, causing the span to drop to the river bed. The remainder of the bridge, except for the hand

rail, was undamaged.

Figure 66

Steel plate girder double track railway "bridge, 0.1 mile southwest of X in Nagasaki. The plate

girders were moved to the left "by the blast, the railroad tracks were "bent out of shape and the trolley

cars were completely demolished. The trolley poles were not knocked down by the blast.
