We conducted a detailed leveling survey along a 42km survey line in Aso volcano from 25 to 30 Sep 2022. This is joint research with Kyoto University, University of Tokyo, Nihon University, Nagoya University and JMA. The purpose of this survey is to measure the ground deformation due to the inflation and deflation of the magma chamber. From SEVO, Prof. Matsushima, Uchida, a technical staff and three students Yoshinaga (M2), Ikeda (M2) and Jyoudoi (B4) attended the survey.
