On 25–30 August 2017, the 15th International Symposium on Geo-disaster Reduction has been held in Oki Islands, Matsue and Kyoto, Japan, focusing on the theme of “Global Strategy for Geo-disaster Reduction”. Through Field Excursion, High Level Forum, Keynote Lectures, Invited Lectures, Scientific Session, Youth Forum and Poster Session, this symposium has successfully provided a platform for scientists, industrial professionals and students to share their research and created a forum to exchange ideas for promoting geo-disaster reduction.

The Oki gneiss was formed at about 250 million years ago, which was the oldest rock on Oki Islands. Some experts argued that the re- gional metamorphic rock records the formation of the supercontinent Pangaea, and could be assumed as the evidence that the Japanese Archipelago was once a part of the Eurasian continent. After that, a large-scale land- slide located in northwestern base of Mt. Ōmine has been investigated. This landslide is located directly below the summit of Mt. Ōmine with a relative altitude Fig. 2 Group photo at the Tsūtenkyō Arch, Oki Islands of 250 m and a steep cliff with a width of 1.6 km and an overall length of about 2.6 km.

Mr. Soichiro Yasukawa, who was representing UNESCO, introduced the section on Earth Sciences and Geo-hazards Risk Reduction in UNESCO, and expressed his hope that this symposium could provide a platform for researches to improve the relationships be- tween geoenvironment and society. In the last greeting speech given by Prof. Masakatsu Miyajima, the president of ICGdR welcomed all the researchers and expressed his gratitude to the organizers.
