Annual Report on Sediment-related Disasters in Japan is now available online!
Annual Report on Sediment-related Disasters in Japan has been a major publication of SABO & Landslide Technical Center (STC) since 1982. It is now at your disposable freely through the STC webpage. It is hoped to be renewed each year under the auspices of the Ministry of Land, Infrastructure, Transport, and Tourism (MLIT), who has regulatory oversight on the national collection of original data.
The report is the result of compiling and edifying efforts on sediment-related incidents and disasters with casualties of the preceding year, reported to the MLIT with items such as: location, weather condition, geology, sediment movement phenomena, sediment volume, damage, recovery, and photos. The expected readers of the report is chiefly local residents in hazard prone areas and related persons in local municipalities, not excluding academic researchers with interest in sediment-related disaster prevention.

Number of dead and missing caused by natural disaster in Japan (1972-2021)
(Cited from SABO and Landslide Technical Center (2022): The Reality of Sediment-related Disasters 2022, 77pp.)
1. Natural disaster (except sediment-related disaster) was cited from Cabinet office “White paper disaster management in Japan 2021” and others were surveyed by SABO Department, Ministry of Land, Infrastructure, Transport and Tourism.
2. Natural disaster (except sediment-related disaster) includes storm, heavy rain, flood, storm surge, earthquake, tsunami, volcanic eruption, and heavy snow.
3. Number of dead and missing caused by snow avalanche is counted only in “Snow avalanche risk area” where houses are located. Mountain climbers were excluded.
4. Number of dead and missing of debris flow and other sediment discharge phenomena, deep-seated landslide: 54 in 1991 and 31 in 1993, including 43 dead and 1missing caused by pyroclastic flows in Unzen-Fugendake.
5. Natural disaster (except sediment-related disaster) includes disaster-related death.
6. Number of dead and missing caused by natural disaster (except sediment-related disaster) in 2021 was not published yet.
7. 2 dead caused by heavy rainfall in northern Kyushu in 2017 is included number of dead and missing of debris flow and other sediment discharge phenomena. Because sediment movement phenomena caused 2 dead was unknown.
