Abstract

Tampusu Mountain (± 1500 m above sea level) is located between two famous geological tourism areas in North Sulawesi, namely Lake Linow and Lake Tondano. The position of Mount Tampusu, as well as the presence of geothermal manifestations in the surrounding area is interesting to study its geological aspects both on the surface and below the surface. This study aims to determine the existence of surface geological structures based on line density, and also to determine the presence and direction of subsurface geological structures based on gravity anomaly data in Tampusu Volcanic area. The fault and fracture density method is used to map the surface geological structure, while the gravity method is used to obtain information about the geological structure of the Tampusu volcanic area between the crater of Lake Linow and the Lake Tondano caldera. The existence of a fault is known to be west of the Lake Tondano caldera which is an extension from east to southeast of the Linow Lake crater. There is a relationship between the distribution map of the bouguer anomaly value and the map of lineament density along the Lake Linow crater to Lake Tondano caldera.
