INTERPRAEVENT International Symposium 2018

HOME > Outline

October 1-4, 2018

Toyama International Conference Hall, Toyama City, Toyama Prefecture, Japan

Purpose of INTERPRAEVENT 2018
Disasters associated with seismic and volcanic activities which are peculiar to orogenic zones occur frequently in the whole Pacific Rim. In addition, catastrophic sediment disasters caused by heavy rains and big typhoons are occurring increasingly in recent years as a result of climate change. People in the orogenic zones had to live with such disasters exerting desperate efforts to mitigate the impacts of such disasters. Technologies for disaster mitigation developed under such circumstances over a long time in the past should be regarded as the world heritage of mankind to be inherited for long in the future. Toyama Prefecture is particularly abundant in historical facilities which are the crystallization of technologies to deal with such disasters. Their historical value should be recognized highly among engineers, researchers, administrators, educators, and many others who are concerned with sediment disasters. Further, messages should be sent to the world emphasizing the importance of (1) verification, development and handing over to the future of the technologies, and (2) soft approaches such as public awareness, disaster risk management and so on. 
     In Toyama Prefecture, a huge amount of sediment discharge of several hundred million cubic meters due to collapse of a mountain triggered by the great earthquake in 1858 blocked up the river to form a natural dam, which later collapsed and caused an extensive damage in the downstream areas in the Toyama plain. SABO works were undertaken continuously for over 110 years thereafter to stabilize the sediment accumulated in the rivers and mountain flanks. The current successful development of the Toyama plain as an area safe from natural disasters and rich in a variety of products is thanks to this long strenuous SABO works. With these historical developments in the background, INTERPRAEVENT 2018 will be held in October 2018 in Toyama.

The main topic of the symposium “Large scale sediment disasters in orogenic zones and countermeasures” is divided into the following six categories, most of which are the same as those of the previous symposium in 2014 in Nara to be consistent in discussions in the series of INTERPRAEVENT, except category IV which has been added to highlight the unique and outstanding characteristics of Toyama.

I. Field observation, Analysis and Modeling
  Geological, Geomorphological or Hydrological Settings
  Characteristics of processes and behaviors 
  Remote Sensing, GPS and GIS Techniques for Mapping and Modeling etc.

II. Catastrophic Disaster
  Triggering mechanism
  Catastrophic disasters caused by volcanic eruption.
  Preparation and urgent measures for catastrophic disasters, and so on.

III. Structural measures and effects
  Efficient design method and site selection of facilities
  Methods of construction considering influence on environment and ecosystem
  Maintenance of facilities
  Secondary use of facilities

IV. Evaluation of historical SABO facilities and historical land use regulations, and their effective use in the future
  Examples of historical SABO facilities 
  Examples of historical land-use regulations in disaster prone areas
  Evaluation of the facilities from the present view point in terms of effectiveness and influence on environment
  Examples of historical local disaster management plan which made use of wisdoms of old generations
  Effective use of facilities considering social and economic change in the future
  ※ “historical” means more than 50 years

V. Risk/Crisis management and non-structural measures
  Advanced monitoring technologies and warning systems
  Methods and procedures for risk management
  Hazard zoning and mapping
  Education and local action aiming at disaster mitigation etc.

VI. Sustainable land-use management 
  Actual state of land-use in hillside areas and issues to address
  Advanced planning methods for sustainable land-use
  Administration for sustainable land-use
  Law aiming at disaster reduction

The symposium will be held from 1 October 2018 to 4 October 2018 in Toyama International Conference Hall

The official language of the Symposium is English (no simultaneous interpretation will be provided).

Keynote Speech
Speakers from several countries will speak on October 1 about SABO of each country with regard to characteristics of recent disasters, policies and measures for disaster reduction, direction of research activities, evaluation of historical facilities etc.

Oral session
Papers will be divided into several groups according to the topics. Oral presentation will be made for several papers in each group judging from the full papers and extended abstracts, with 15 minutes for presentation and 5 minutes for question and answers each.  

Poster session

Posters will be displayed on October 2 and 4, with core time in the afternoon on October 2 and 4. Papers for posters will be selected in reference to the extended abstracts

Panel discussion

Panel discussion will be made comprehensively on characteristics of disasters, planning of facilities, evaluation of effectiveness of facilities etc., with focus on (1) technologies developed and applied to fight against large scale disasters triggered by extreme weather events, volcanic eruptions and earthquakes which are peculiar to orogenic zones, and (2) evaluation of historical SABO facilities and historical land-use regulations, and their effective use further in the future. 

Study Tour 

One day study tour will be made to the site where the massive collapse of a mountain occurred triggered by “Hietsu Great Earthquake” (1858), and then to the sites where sediment disasters occurred due to collapse of a natural dam and measures were undertaken thereafter to prevent such disasters to take place again in the future. 

A study tour to Kurobe Gorge and other places is arranged for the accompanying persons. 

Registration of technical contributions for oral presentation and poster presentation

The full papers will be recorded in CD-ROM and will be distributed together with the compilation of the extended abstracts at the symposium.

Those who wish to make an oral and/or poster presentation should submit the abstract (A4 size, 2 pages) to the Organizing Committee in advance,   for screening for “Accepted”, “Not accepted” or “Need improvement”.

Organizing Committee will send notification on “Permission of presentation” to those whose abstracts and the full papers have been accepted, after the pre-registration is completed.

Contribution can be made through on-line system. The website for contribution will open in June 2016.

The procedures for the contribution will be announced in the second circular in July 2017.
