[SCG58-09] Preliminary report on geothermal structure revealed by geological and MT surveys around Akayumatasawa river in Sanzugawa caldera, NE Japan
Keywords:geothermal structure, MT, geothermal fluid
There are a number of high-temperature hot springs along Akayumatasawa river that flows through the center of Sanzugawa caldera. This study reports the resistivity and geological structures based on MT surveys and field surveys around Akayumatasawa. In addition to these structures, the gravity structure, distribution of hot springs, and hypocenter clusters under Akayumatasawa indicate existence of geothermal fluid that is ascending from deep subsurface.
