摘要: There have been a number of observed precursors volcanic activities- such as earthquake, surface inflation, specific gas emission, temperature hot spring- at Mt. Baekdusan since 2002. We identified the increase volume magma chamber beneath we an inflation trend vertical and horizontal displacement around Cheonji caldera lake by using precise leveling data from 2002 to 2009. The changed deflation in 2010, again after while. Utilizing inflated (46.33 mm) on northern slope 2003, calculated change Baekdusan. was about 0.008 () 2003. It indicated that new (0.008 ) injected 5 km below
