Recently, increasing a possibility of volcanic activity • A serious of micro-seismic events • Increasing a temperature of hot spring • Gas (CO2, He, H2, CH4) emissions (Wunderman et al., 1994) • USED Datasets • 41 JERS-1 SAR data • 10 ERS-1/2 SAR data Slow Deformation of Mt. Baekdu Stratovolcano Observed by Satellite Radar Interferometry Sang-Wan Kim and Joong-Sun Won Yonsei University, Korea
