Self-potential (S.P.) measurements exhibit that the large and positive S.P. anomaly is observed on the summit area of Miyake-jima volcano, while the significant anomaly related with the volcanic activity is not found on Esan volcano. A repeated measurement of the S.P. field on Usu volcano reveals the large and positive anomaly has been maintained during this decade. Different aspect of the S.P. fields probably depends on the differences in the hydrothermal system of each volcano.
