Resistivity structure survey of deep part of Osore-volcano by magnet telluric method.

Abstract Although Osore-zan volcano had repeated volcanic activity until 0.08 ma, activity declines and geothermal activity had continued long time with no volcanic eruption. There are several hotsprings and fumaroles around Lake Usori that is caldera lake of Osore-zan volcano. We are expecting that it may be having different feature about volcanic structure from other active volcanoes. Here we carried out MT survey around Osore-zan volcano to clarify deep part of volcanic structure.
