6 years after the landslide in Hiroshima The population in the disaster area is declining and the population is aging August 20 4:39
It has been 6 years since 20 days since the sediment disaster in Hiroshima that killed 77 people. In the disaster-stricken area, while reconstruction is progressing and the population is declining and the population is aging, the challenge is how to convey evacuation support and disaster experiences.
In the sediment disaster of Hiroshima City on August 20, 2014, 77 people including disaster-related deaths caused by debris flows and landslides at 166 locations in the city due to heavy rain exceeding 120 mm per hour at the maximum. Died.
After the disaster, the country and Hiroshima Prefecture proceeded with construction works such as erosion control dams at 99 locations in Hiroshima city and were completed in the beginning of this month.
Of these, the sabo dam constructed at Yagi 3-chome, Asanan-ku, Hiroshima-shi, where 41 residents were killed, has a space equivalent to one soccer court to catch the spilled sediment.
The Chugoku Regional Development Bureau of the Ministry of Land, Infrastructure, Transport and Tourism explains that even if a landslide disaster of the same scale as six years ago occurs, it is possible to prevent the damage from flowing into the residential area.
On the other hand, the underground drainage facility for temporary storage of a large amount of rainwater and the road for evacuation, which is being constructed in Asa-Minami Ward, was planned to be constructed by the end of last year, but the ground was hard and excavation work was difficult, prospect of completion is that there is no standing.
In the disaster-stricken areas, the population continues to decline as younger generations move to other areas.
In some areas, the percentage of elderly people aged 65 and over reaches nearly 40%, and the challenge is how to convey evacuation support and disaster experiences.
