Researching Active Volcanism

Better understanding of active volcanism has potential to improve the reliability of volcanic hazard assessments and the safety of surrounding populations and economics. By analyzing the data acquired by the Sakurajima Muography Observatory (SMO) [1-6], we investigate the evolution and movement of materials under the active craters, the time and duration of the occurrence of volcanic processes. We plan to utilize the developed muographic procedures as part of a complex volcanic hazard assessment procedure. The research group plans to join volcanological researches conducted at European volcanoes.
