[SVC33-P07] Monitoring of Volcanic activity on Mt. Baekdu by using remote and field observation data: Korea Meteorological Administration(KMA)
Keywords:Volcano, Volcano monitoring, remote, diffusion model of volcano ash
Mt. Baekdu’s caldera was created in 946~947 by colossal(VEI 7) ‘Millennium’ eruption. Mt. Baekdu is an active volcano on the border between China and North Korea. Because of its location, satellite remote sensing is one of the important tools for understanding of volcanic activity.
We used Satellite images(Sentienl-1, Landsat) to measure deformation of Mt. Baekdu. SAR image(Sentinel-1) is analyzed to obtain the surface displacement. Optical and thermal infrared images are analyzed to obtain surface temperature and caldera area(called `Haven Lake`). We are regularly monitoring volcanic activity using remote analysis.
In 2018, the Korea Metorological Administration(KMA) established the Volcano Specialized Resarch Center, which is conducting joint research between Korea and China. Through this joint research, we have been obtaining field observation data in Mt. Baekdu. We acquire volcanic gas and temperature data from hot spring water and observe surface defromation with the EDM installed in Chanbaishan Tianchi Volcan Observatory(TVO).
Therefore, we monitor volcanic activity not only remotely, but also by regularly analyzing field observation data. As a result of analysis through satellite images and field observation data, it is judged as Mt. Baekdu is currently in a stable state.
In addition, we monitor volcanoes around the Korea Peninsula using VAAC. If there is volcanic activity around the Korea Peninsula including Mt. Baekdu, the diffusion range is calculated using the Ash Diffusion Model.
