Trees in the Hypocenter – The blast directly above these trees split tree trunks in half. 

Damage in 1km radius of Hypocenter

“Almost all of the humans and animals in this area were killed instantly by the immense explosion, pressure, and heat waves. Houses, buildings, and wooden columns turned to ruins and the area would soon become engulfed in fire. Gravestones were destroyed. Trees and plants both big and small were all leveled in the direction of the Hypocenter, losing their branches and catching fire.”

Municipal Shiroyama National School

Around 1,400 students out of the 1,500 students in this school, located 500m west of the Hypocenter, are presumed to have died in their homes.    

Municipal Yamazato National School  - Around 1,300 students out of the 1,581 students (as of June 30, 1945) in this school, located 0.7m from the hypocenter, are presumed to have died from the atomic bombing    

Damage Within 1 to 2 km Radius of the Hypocenter

“Some of the humans and animals died from the blast wind and heat wave felt in this area. The majority, however, suffered from minor to severe injuries. Approximately 80% of the houses, buildings, and wooden columns were destroyed and what remained would soon fall victim to the subsequent fires that would break out. Concrete and steel columns were not destroyed. A portion of the greenery withered and died.”

Railway services were quickly restored and operations resumed on August 12.However, the majority of other railway stations and facilities were not back in service yet.

In the middle-left area of this picture, the concrete remains of the Nagasaki Medical College Hospital, located 1km south of the hypocenter, can be seen (photo taken two months after bombing). The inside of the hospital was burned out by fire, leaving only the external skeleton and rendering the building useless.

Restoring the City

The next challenge awaiting for those who narrowly escaped the atomic bomb was the struggle for survival.

For the first few days, they camped along the montainside and riverside. Gradually, they started to build a zinic hut using collected materials from the ruins. The air raid shelters were also used as their temporary houses.

 Public housing were developed but only few hundred houses were built and the shortage of housing continued.

Houses were built in air raid shelters after the war ended. Date of Photograph: 15 days to 1 month after Atomic Bombing
