Abstract
As is well known, the last eruption of Mt. Fuji was the Hoei eruption in 1707, and there has been no eruption for more than 300 years. It is common knowledge in volcanology that Mt.Fuji is a very young volcano and it is 100% certain that an eruption will occur in the future. Because of its proximity to the Tokyo metropolitan area, it is believed that an eruption would cause enormous damage to Japan, which has become IT-oriented. In October 2020, our group set up a permanent total magnetism observation point at an altitude of 1400m, which will serve as a reference point for future geomagnetic observations. In evaluating observation data, in order to judge whether it is an artificial change due to a physical change in the position of the sensor (sensor pole tilted due to force majeure, etc.) or a true change in the natural world is very important. Therefore, in the summer of 2022, we conducted geomagnetic preliminary observations from the summit to the vicinity of the 6th station and succeeded in selecting candidate sites for future permanent observation points. In the future, we intend to conduct electromagnetic monitoring of Mt. Fuji as the IUGG-EMSEV project.
