摘要

Large and powerful Typhoon No. 19 (Typhoon Hagibis) made landfall on the Izu Peninsula on 12 th October 2019, and it brought widespread and record-breaking torrential rain across Japan, especially in Eastern Japan. Emergency warning was issued in Tokyo and 12 prefectures, and many slope failures and debris flows were caused. It marked the largest number of sediment disaster occurrences by a typhoon since 1982 that the statistics have been started to be recorded. 952 sediment disasters were caused by the typhoon (as of 24 th December 2019), and 16 people were killed and one person is missing. In Tohoku region, most disasters happened in Iwate, Miyagi, and Fukushima prefectures. From 1 : 00 am, 12 th October to 12 : 00 am, 13 th October (two days) total precipitation (observed by AMeDAS of Japan Meteorological Agency) was 594 mm in Hippo, Marumori-machi, Miyagi prefecture, and 466.5 mm in Fudai, Iwate prefecture. From the above, Japan Society of Erosion Control Engineering organized “Emergency investigation team for the sediment disasters in Tohoku region caused by Typhoon No. 192019” and performed the investigation for three times. The survey results have been published with the title “Sediment disasters caused by Typhoon Hagibis on October, 2019 in Tohoku region” to the Journal of Japan Society of Erosion Control Engineering, volume 72, No. 6, in 2020 (in Japanese, with English Abstract). This paper provides, as part of a brief summary of these findings.
