[SVC45-P07] Gravity surveys in southwestern part of the Kirishima volacnic area
Keywords:Kirishima volcanic area, gravity survey, hot springs, subsurface structure
The Bouguer anomaly map shows a gravitational steep incline, which has a strike of NE-SW direction, near the Kirishima Rehabilitation Center of Kagoshima University in the Maruo hot springs. It is explained that this steep incline indicates a fault structure. And a low Bouguer anomaly area exists at the western part of the steep incline. So it is inferred that this is a depression structure filled with some low density layers and can be a hot spring aquifer.We are grateful to Mr. Yusaku Yonekura who had progressed this study.
