Abstract

Mt. Baegdu, a Cenozoic stratovolcano, was studied using twenty-three JERS-1 SAR and two ERS-2 SAR data sets. We investigated surface changes for 6 years from 1992 to 1998 using three aporoaches: i) interferograms of large altitude of ambiguity, ii) the 2-, iii) and 3-pass DInSAR technique. After analyzing 11 differential interferograms having various time intervals, we concluded is suggested that several tens of kilometers of surfaces are subsiding centered around southwest part of Mt. Baegdu. When the observed displacement is assumed to be only in the vertical direction, the rate of surface subsidence is about 9 cm/year. Although these results are not conclusive due to lack of ground truthing, it must be very useful as background information for long-term monitoring.
