The predictions are to be used to draw up effective evacuation plans for residents of the three prefectures. Up to 750,000 residents would have to evacuate in Shizuoka and Yamanashi prefectures in the event of an eruption, according to an earlier government estimate. The task force has been ordered to update evacuation plans for residents who are expected to be in danger from ash clouds and falling debris in the event of an eruption, NHK reported. The news comes after an announcement by a Ryukyu University professor that an eruption may be overdue. According to retired professor Masaki Kimura of Ryukyu University, recent phenomena, such as a pressure buildup in Mt Fuji’s magma chamber, indicate an eruption of Mt Fuji should have taken place in 2011 with a four-year margin of error ending in 2015. The team has been charged with studying seasonal patterns and crater shapes in order to create simulations that accurately predict the behavior of the ash clouds that are likely to result from a large eruption. A survey carried out by the University of Tokyo’s Earthquake Research Institute in May of 2012 found a 30-km fault running from Gotemba in Shizuoka Prefecture beneath Mount Fuji. Research results indicated it is likely to be active. If the fault sets off an earthquake, researchers say the slopes would mo

La dernière éruption du Mont Fuji date de 1707 mais trois départements du Japon (Yamanashi, Shizuoka et Kanagawa) viennent – on ne sait jamais – de mettre en place un plan d’évacuation en cas de coulées de lave ou de nuages de cendre… Tôkyô, mur peint dans le quartier de Nishi-Nippori.
