Typhoon No. 10 threatens Japan: unprecedented heavy rainfall and disaster risk

Such extreme precipitation could lead to record-breaking rainfall levels, with the potential to exceed 150% of the maximum historical rainfall recorded for the area. This elevated ratio significantly heightens the risk of casualties, as evidenced by a joint study from the Japan Weather Association and Professor Motoyuki Ushiyama of Shizuoka University. The research suggests that when the historical rainfall ratio reaches 100%, casualties are likely to occur, and a ratio exceeding 150% could sharply increase the number of fatalities.
