| | Abstract | | Now we focus the Kurikoma volcano closely at the triple junction of borders of Akita, Iwate and Miyagi prefectures, northeast of Japan. Kurikoma volcano is one of important active volcanos and its most recent striking activity was phreatic eruption in 1944. The site of 1944 eruption is now remained as a crater lake called Lake Showa. Besides the Lake Showa, upstream of a gorge called Jigoku-dani and volcanic gas is even now emitted there. We installed several AMT sites on the volcanic body of Kurikoma volcano and one of sites is alongside Lake Showa and Jigoku-dani. We just collected the time series of geomagnetic and telluric date of AMT and report the characteristics of primary data and initial analyses using phase tensor and two-dimensional structure analysis. |
