Abstract

Many low-frequency earthquakes were observed under Mt. Fuji from October 2000 to May 2001, and it was pointed out that the volcanic activity of Mt. Fuji might increase. In order to monitor the volcanic activity, we performed precise relative gravity measurements over Mt. Fuji area by using LaCoste & Romberg gravimeters since 2002, and investigated temporal change of gravity over Mt. Fuji for three years. The number of the low-frequency earthquakes has decreased since June 2001, and no significant gravity temporal changes were observed, however the data obtained form an important data base to investigate the future volcanic activity of Mt. Fuji.
