| Research Abstract |
On the basis of geological, chronological, petrological observation, we investigated the geneses and frequencies of phreatic eruptions and landslides and their relationships. Some phreatic eruptions intimately relate to landslides but others do not ; ascending magma also relates to their occurrences. Detailed study revealed the frequencies and relationship of phreatic eruptions and landslides during the last 4500 years at Chokai. Genesis and history of the 1895-1896 eruption at Zao volcano was also studied.
