The 14th International Symposium on Geo-disaster Reduction (ISGdR) was held on 10-13 October 2016 in Chengdu, China. The 15th ISGdR is to be held at the Shimane University in Matsue, Japan from 26 to 31 August 2017. This article firstly outlines the background and aims of the ISGdR, reports on the 14th ISGdR in Chengdu, China, and then announces the plans for the 15th ISGdR in Matsue, Japan. Finally, it acknowledges for contributions for the organization of the 14th ISGdR.
1.1 Background of the ICGdR and ISGdR
The International Consortium on Geo-disaster Reduction (ICGdR) is an international non-governmental and non-profit scientific organization legally registered as a non-profit organization in 2013 in the Shimane Prefecture according to the Japanese law (Wang, 2014). Before the official establishment of the ICGdR, the core members had conducted preparatory activities for 10 years. In 2003, the first symposium was held at Kanazawa University, Japan for the mitigation of geo-disasters in the areas around Japan Sea, which drew attention of researchers and engineers from China, Korea and Japan. The second, third and fourth symposiums were also held at Kanazawa University. Then, the fifth and sixth symposiums were held at Chang’an University and Kunming University of Science and Technology in China, respectively. In 2009, the symposium was renamed as “The International Symposium on Mitigation of Geo-disasters in Asia” in order to include more countries and to cover a larger area. The seventh event was then held in Northeast Forestry University, China. The eighth and ninth symposiums were held in National Far-East Technology University, Vladivostok, Russia in 2010, and Universitas Gadjah Mada, Yogyakarta, Indonesia in 2011, respectively. Gradually, the event transformed from regional to international. In 2012, Shimane University, Japan organized the 10th symposium, and about 100 participants attended this event. According to a regional initiative from Asia, the participants, of which most are experts on geo-disaster reductions, had intent to establish an international consortium on geo-disaster reduction. In May 2013, the organizing meeting of the International Consortium on Geo-disaster Reduction (ICGdR) was held in China Institute of Disaster Prevention, Beijing, China. And later, the legal registration was completed in August 2013 in Matsue, Japan.
In 2013, the 11th symposium was successfully held in Kathmandu, Nepal. The Nepalese Prime Minister (the Chairman of the Interim Council of Ministers) inaugurated this event and gave great concern to geo-disaster reduction in the region. Based on the success of the last ten symposia, the core members of ICGdR have agreed to open the symposium to now include the whole world, as well as Asia. At this time the symposium was officially renamed the “International Symposium on Geo-disaster Reduction (ISGdR)”. The 12th and 13th ISGdR was held in Fullerton, California, USA in 2014 and in Prague, Czech Republic in 2015, respectively.

High Level Forum
The High Level Forum was chaired by Prof. Fawu Wang. Five famous experts delivered their plenary lectures focusing on the theme of “Global Strategy for Geo-disaster Reduction” (Fig. 4): “Importance of communicating natural hazards to the public - an Oregon, USA example” by Prof. Scott Burns (President of IAEG), “Disaster risk reduction in one belt one road area” by Prof. Peng Cui (Academician, Chinese Academy of Sciences), “Study on control theory of landslide based on the evolution process” by Prof. Huiming Tang (Vice President, China University of Geosciences, Wuhan, China), “New technologies for landslide monitoring and rapid mapping” by Prof. Nicola Casagli (Deputy Director of UNESCO Chair on the Prevention & Sustainable management of Geo-Hydrological Hazards, University of Florence, Italy), “Lessons learned from recent damaging earthquakes in Taiwan, Japan and Italy” by Prof. Masakatsu Miyajima (Kanazawa University, President of ICGdR).
The Keynote Lectures included 8 plenary lectures which were divided into two sections. The first section was chaired by Prof. Masakatsu Miyajima and Prof. Qiangong Cheng. Firstly, Prof. Fawu Wang presented their research on landslide dam to predict the failure time through in-door and out-door landslide dam model tests and field investigation. The second keynote lecture from Prof. Guoxiang Liu concentrated on a case study for mapping and inventorying active rock glaciers in the Northern Tien Shan (China) by InSAR. Prof. Qiang Xu introduced their study on diffuse failure landslides including a landfill flow-slide, some loess landslides and a landslide of loose deposits, and attempted to assess the initiation of diffuse failure landslides. At the end of first section, Prof. Hengxing Lan gave a lecture on geo-hazards risk assessment for Sichuan-Tibet interconnection project of state grid based on the engineering geological conditions, regional geological condition, geological hazards investigation, project design, the remote sensing interpretation and numerical modelling.
The second section of Keynote Lectures was chaired by Prof. Huiming Tang and Prof. Nicola Casagli. Prof. Xianzhang Ling’s lecture highlighted two important research topics on vibration response of railway traffic subgrade and vibration response of road traffic subgrade with heavy load in cold regions. Furthermore, the finished fundamental work on above-mentioned topic was discussed and elaborated. Prof. Yu Huang presented research on the flow slides in MSW landfills and provided a scientific basis for hazard prevention and risk evaluation in the landfill area. Two kinds of mesh free method, a smoothed particle hydrodynamics (SPH) model, and a modified moving particle semi-implicit (MPS) model were proposed to predict the propagation of the flow slides in MSW landfill in two dimensional and three dimensional. Prof. Ranjan Kumar Dahal introduced major geological and geomorphological issues in central Nepal after the Gorkha Earthquake and conducted detail analysis to understand liquefaction problem, landslide problem and topographic and basin effect. At the end of Keynote Lecture, Prof. Guangqi Cheng proposed a practical 3D coupled solid-fluid simulation technique by using DDA and SPH to analyze the formation and failure characteristics of the landslide dam. The developed simulation technique has been successfully applied to simulate a practical landslide dam and its effectiveness and practicality have also been validated.
