Mt. Baekdu is known as a still active volcano and is located on the border betweenKorea and China. Although some gentle volcanic movements were only observed recently, Mt.Baekdu were notably erupted around 1000 years ago whose volcanic ash was found on Hokkaido,Japan. So necessity of the periodic observation was always existed. Especially after the fact that asignificant magma storage is under the Mt. Baekdu was suggested, the importance of magmasource movements were gradually larger. As SAR could observe wide area with centimetreprecision, SAR-derived deformation based magma source modelling approach was widely applied.In this study, we estimated the location of magma source under the Mt. Baekdu by adapting pointsource (Mogi) model to a deformation rate map. For that we collected multi-temporal Sentinel-1interferometric wide mode acquisitions from descending orbits. In succession we generatedinterferometric pairs whose longest temporal baseline is 48 days because the study area tend to betemporally decorrelated. After that deformation rate map was generated by stacking qualifiedmulti-temporal interferograms. As a result, the volume change and source depth were about 0.0066km3 and 7.4 km respectively. This results was very similar to previously published parameters.The final result would validate with the same result from the independent data, which is multitemporal Sentinel-1 interferometric wide mode acquisitions from ascending orbits.
