The central government and Hiroshima Prefectural Government plan to place mudslide sensors in the northern part of the prefecture where at least 90 people were reported dead or missing as of Friday, the Yomiuri Shimbun reported Friday.
The land ministry and Hiroshima government plan to place around 10 sensors in the Asaminami and Asakita districts, which suffered heavy damage from landslides and are in danger of more mudslides, so residents can be alerted, the report said.
Wires from the sensors will be stretched over terrain in mountain valleys, and if they are severed by a mudslide, the sensors will activate a siren.
Such sensors were set up in the Kii region in western Japan in 2011 when the stront Typhoon Talas hit the country, causing floods and damage especially in Nara and Wakayama prefectures.
The search for missing people in Hiroshima was suspended temporarily Friday morning due to heavy rain, NHK reported.
