Xu Jiandong et al Attended South Korea “International Conference on Volcanic Hazard Mitigation”

2016/12/30 9:13:48

The 1st International Conference on Volcanic Hazard Mitigation (VHM 2016) was organized and hosted by Korea Society for Volcanic Hazard Mitigation (KSVHM). It is also the fifth international symposium of KSVHM. The conference was held in Golden Tulip Hotel, Seoul, South Korea on March 30~April 1, 2016. The subject of this conference is “development and application of multiple technologies in volcanic hazard mitigation”. More than 30 scientists and engineers from South Korea, China, Japan, the United States, the Philippines and Iceland attended the conference.

Although this conference was held in Seoul, South Korea, it focused on Changbaishan Tianchi Volcano, the most dangerous volcano in Northeast Asia. The conference intensively studied the eruption history, hazard type and distribution, monitoring techniques, hazard classification and assessment, and disaster prevention techniques of Tianchi Volcano. In addition, volcanists from the Philippines, Japan and Russia also separately introduced volcano distribution, volcano hazards and current monitoring condition of their respective countries and informed the attendees the volcano activities and disaster handling of various countries in the world.

   Professor Peter Webley of American University of Alaska introduced a real-time volcanic ash decision support system (DSS) developed by its research team.  This system is connected to the data of multiple real-time monitoring satellites, calculates volcanic disaster situation and generate suggestions for countermeasures based on real-time data of weather, volcano eruption and atmospheric convection, and provides real-time online service. Multiple Korean scholars systematically introduced “real-time volcanic ash monitoring and early warning system of Changbaishan Tianchi Volcano” developed by them. They chose Tianchi Volcano as the source region of disasters, and developed a Tianchi Volcano early warning system by using real-time meteorological data and a volcanic ash spread model. This system chooses a network server as a platform and may issue early warning against volcanic ash distribution and disaster situation of Changbai Mountain in real time and provide a reference for aviation and people’s life.

In respect to volcanic ash hazard, Researcher Xu Jiandong of CEA Institute of Geology studied the assessment technology for site selection of nuclear power plants, and described how to calculate influence probability of volcanic ash on a nuclear power plant by disaster probability method through disaster research of volcanoes active in different periods within the range of the site of a nuclear power plant. Assistant Researcher Pan Bo introduced the eruption sequence of Tianchi Volcano since Late Pleistocene Epoch and thinks Tianchi Volcano experienced tremendous explosive eruption twice since Late Pleistocene Epoch, and the generated volcanic ash reached Northern Pacific Region under the influence of monsoon and affected the whole Northeast Asia.

This conference lasted only three days and didn’t have many attendees, but through comparison with foreign countries, it still deeply impressed us, mainly in two aspects: 1) China needs to raise technical reserve for disaster reduction. South Korea is in the influencing range of Changbaishan Tianchi Volcano, but the impact of the eruption of Tianchi Volcano on it is much smaller than the impact on China and North Korea. Nevertheless, it inputs dozens of researchers and millions of dollars to develop “a volcanic ash disaster system of Tianchi Volcano”. Its practice is worth learning to us. 2) Basic research is inadequately combined with scientific application. At this conference, many scholars from the United States, South Korea and Iceland are not volcanists but software designers. They applied modern cloud service and big data to integrate the basic research approaches and models of volcanists and various data to form a complete platform, for disaster handling and decision making. At this point, China still has a long way to go. In China, basic scientific research data is mainly used in publication of papers and reporting of projects and is seldom integrated with related science and technology companies or combined with social demands.

Above is introduction and cognition to South Korea “International Conference on Volcanic Hazard Mitigation” this time. Although its time is short, this conference provided much knowledge and experience for the attendees. Particularly, Changbaishan Tianchi Volcano is a research base of our research center of active volcanoes. Its safety is the mission and duty of our research center. The series research reports of this conference on Changbaishan Tianchi Volcano enriched our research knowledge, broadened our horizon and made us know our shortfalls and feel the pressure. In the future, we will work even harder, strengthen international exchange and improve China’s volcano disaster reduction techniques and countermeasures.
