1st CircularIntroduction
It is our pleasure to announce that the 8th International Geotechnical Symposium on Disaster Mitigation (8IGS)
will be held in Sapporo, Japan, on May 2020 which is organized by ATC3 under the auspices of Japanese
Geotechnical Society. This series of conference has been organized under Asian Technical Committee 3 on
Natural Hazards (ATC3) of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE)
which is currently chaired by Prof. Mitsu Okamura of Ehime University, Japan. The past events were highly
successful respectively in Astana 2005, Yuzhno‐Sakhalinsk 2007, Harbin 2009, Khabarovsk 2011, Inchon 2013,Chennai 2015 and Chengdu 2017. We would sincerely appreciate your contribution to the symposium.

GoalTheme

Landslides caused by heavy rain and ground disasters
caused by earthquakes have occurred frequently inAsia. In Japan, landslide disasters by heavy rain
occurred in wide areas of western Japan last year. The
Hokkaido Iburi east earthquake caused many slope
failures in the hilly area of Atsuma town andliquefaction damage in the residential area of Sapporo
city. Earthquake induced geo‐disasters in Sulawesi andJava, Indonesia, and in Taiwan and the Philippines havealso been reported.
This symposium aims to share the latest intelligenceand knowledge of Asian countries on geotechnicalnatural hazards and to establish a framework for Joint
research for future collaboration.

Field Trip
The Hokkaido Iburi eastern earthquake occurred at 3:07
AM on September 6, 2018. The epicenter was in themiddle of the Iburi region, at 42.7 degrees north latitude
and 142.0 degrees east longitude. The magnitude wasestimated to be 6.7 and the hypocenter depth to be 37
km.
In the hilly area of Atsuma Town, innumerable slope
failures occurred, and infrastructure and housing weredamaged. Regarding the situation of Atsuma Town, theaerial photography video of the Hokkaido Development
Bureau of the Ministry of Land, Infrastructure, Transportand Tourism is available at the following URL.
In the site tour, the situation of slope failure in Atsuma
Town is observed, the situation of collapsed sediment isobserved, and geotechnical characteristics of collapsed
sediment are explained.
