| | Abstract | | Evolution of seismic reflection structure beneath an active volcano is presented, which is revealed with four rounds of seismic experiments during 2008 to 2011 in one of the most active volcanoes, Sakurajima Volcano, Japan. The changing reflectors are distributed in the two ranges 2 to 6km and 7 to 9 km in the depth. Evolution of the seismic reflectors has certain correlation with the activity level of the volcano. |
