Recently there are many disasters caused by volcanic activities such as the eruptions in Tungurahua, Ecuador(2014) and $Eyjafjallaj\ddot{o}kull$, Iceland(2010). Therefore, it is required to prepare countermeasures for the disasters. This study analyzes the Baekdu Mountain area, where is the risky area because it is active volcano, based on the observed data and scientific methods in order to assess a risk, produce a hazard map and analyze a degree of risk caused by the volcano. Firstly, it is reviewed for the research about the Baekdu mountain volcanic eruption in 1215(${\pm}15$ years) done by Liu Ruoxin. And the factors causing volcanic disaster, environmental effects, and vulnerability of Baekdu Mountain are assessed by the dataset, which includes the earthquake monitoring data, the volcanic deformation monitoring data, the volcanic fluid geochemical monitoring data, and the socio-economic statistics data. A hazard, especially caused by a volcano, distribution map for the Baekdu Mountain Area is produced by using the assessment results, and the map is used to establish the disaster risk index system which has the four phases. The first and second phases are very high risky area when the Baekdu Mountain erupts, and the third and fourth phases are less dangerous area. The map shows that the center of mountain has the first phase and the farther area from the center has the lower phase. Also, the western of Baekdu Mountain is more vulnerable to get the risk than the eastern when the factors causing volcanic disasters are equally applied. It seems to be caused by the lower stability of the environment and the higher vulnerability.

The Korea had been known as a safe region in volcanic disaster. However, precursor phenomena for volcanic eruption in mountain Baekdu have been frequently reported in these days. Therefore, the number of volcano experts, who warn the volcanic eruption in the Korean peninsula, has been increased. This paper describes the plan for developing volcanic disaster response system for mountain Baekdu. First, disaster prevention business system of National Emergency Management Agency(NEMA) and related IT-based systems are analyzed. Second, business processes for volcanic disaster response are derived based on the business system. Third, The system architectures are designed referred to related disaster response system, and required spatial information is investigated. Finally, we implement the pilot system to test the suggested volcanic disaster response system. Applying suggested volcanic disaster response system to NEMA, additional test and system supplementation should be carried out. We expect that the complete volcanic disaster response system, which will be implemented based on this research, will minimize the volcanic disaster damage in the area of Korea, China, and Japan.

Korea had been known as safe region regarding volcanic disasters. On the other hand, Baekdu mountain experienced a large eruption one thousand years ago and the precursor phenomena for a volcanic eruption have been frequently reported these days. Therefore, a number of volcano experts, who warn of a volcanic eruption on the Korean peninsula, has increased. This paper describes the utilization plan and evolution of developing volcanic disaster response system based on spatial information and scientific modeling process for Baekdu mountain. First, the business processes for volcanic disaster response are derived based on an analysis of business system and related IT-based systems. Second, the design and development of a volcanic disaster response system are derived based on the business process. Third, a utilization plan is suggested to maximize the efficiency of the system. The application of the suggested volcanic disaster response system to NEMA, additional tests and system supplementation should be carried out. The complete volcanic disaster response system, which will be implemented based on this research, is expected to minimize the volcanic disaster damage in the area of Korea, China and Japan.

In recent years, earthquakes and volcanic activity have been occurring actively in Japan, China, and Southeast Asia in the central Pacific Rim, and the cycle interval is shortening. In addition, there is Baekdu mountain, which is a large active volcano in Korea. On the other hand, the legal system and guidelines related to volcanic ash are very limited to counteract volcanic disasters. The volcano manual does not present specific countermeasures against volcanic disasters. The preparation of systematic disaster prevention measures against an eruption of Mt. Baekdu and the volcanic activity in Japan and China, which are occurring continuously, is necessary. Therefore, this study suggests an improvement to the relevant laws and regulations against volcanic disasters to analyze the aviation safety manual and relevant legal system. The problems with the current legal system are improved by modifying the legal system related to the air traffic sector when volcanic disaster occurs, and it is expected that more efficient manuals and guidelines will form the basis for the smooth operation of the manual at a disaster site.

Korea has been known as volcanic disaster free area. However, recent surveying result shows that Baekdu mountain located in northernmost in the Korean peninsula is not a dormant volcano anymore. When Baekdu mountain is erupting, various damages due to the volcanic ash are expected in South Korea area. Especially, volcanic ash in the air may cause big aviation accident because it can hurt engine or gauges in the airplane. Therefore, it is a crucial issue to interrupt airplane navigation, whose route is overlapped with volcanic ash, after predicting three dimensional dispersion of volcanic ash. In this paper, we deals with 3D visualization techniques for volcanic ash dispersion prediction results. First, we introduce the data acquisition of the volcanic ash dispersion prediction. Dispersion prediction data is obtained from Fall3D model, which is volcanic ash dispersion simulation program. Next, three 3D visualization techniques for volcanic ash dispersion prediction are proposed. Firstly proposed technique is so called 'Cube in the Air', which locates the semitransparent cubes having different color depends on its particle concentration. Second technique is a 'Cube in the Cube' which divide the cube in proportion to particle concentration and locates the small cubes. Last technique is 'Semitransparent Volcanic Ash Plane', which laminates the layer, whose grids present the particle concentration, and apply the semitransparent effect. Based on the proposed techniques, the user could 3D visualize the volcanic ash dispersion prediction results upon his own purposes.
