Japan-Canada Joint Research for Prediction of
Occurrence and Movement of Catastrophic Landslides


The Working Group for Prediction of Rapid Landslide Motion(WG/RLM) was proposed by K, Sassa and approved at the meeting of the International Geotechnical Societies' UNESCO Working Party for World Landslide Inventory(WP/WLI) in August, 1992.In June 1992,K.Sassa of the Disaster Prevention Research Institute, Kyoto University and S.Evans of the Geological Survey of Canada agreed to start the Japan- Canada Joint Research on the Prediction of Rapid Landslide Motion. This bilateral joint research is closely related to the activity of WG/RLM and compose of its core part. The first joint study meeting and the field trip to the Ontake debris avalanche and the Jizukiyama landslide were organized in Japan during 24 May and 2 June 1993, and the second joint study and the field trip to the Unzen volcano and the Mayuyama landslide were implemented during 24 July and 7 August 1994 in Japan, and the third joint meeting and the field study at the Frank Slide were conducted during 22 April and 8 May in Canada. The fourth meeting was organized again from 11 to 30 September in Kyoto. The international Symposium on Prediction of Rapid Landslide Motion was jointly organized by the Japanese Ministry of Education, Science, Sports and Culture, Kyoto University and WG/RLM,
This joint research is financially supported by the Monbusho International Scientific Joint Research Program in the Japanese side and by the Japan Science and Technology Fund in PACIFIC 2000 Program of the Canadian Government, The aim of this research is to publish the present frontier of the world to predict rapid landslide motion as a book "Rapid Landslides-Initiation, Motion and Hazard Assessment-", after international and interdisciplinary examination and discussion in meetings and fields of landslides. This joint research in the Frank Slide, Canada and the undrained loading ring shear test of samples taken from the Frank Slide were filmed in the Frank, Canada and the DPRI, Kyoto University by BBC, UK, and they were introduced in "The Runaway Mountain" of the BBC science program: Horizon in October 1995. A copy of the 49 minutes video tape is obtained from
