Abstract

Mostly geothermal power plant placed around volcano on land. Sangihe Archipelago, the northern of Sulawesi Island known as volcano arc that formed by the subduction of Philippines plate beneath Micro-Sunda plate. The geothermal source is located under sea level, this condition needs some approach of remotely applied sciences. The possibility study is conducted by bathymetry, gravity, magnetic, and regional geology. The objective is searching the high value gravity at the high topography as indication of the magmatic product on the seafloor and the low value of magnetic as indication of the active heat resources. A profile section from Philippines oceanic plate to the Celebes Sea by using each data shown a sequence of subduction product, such as trench, outer-arc ridge, and volcano arc. Geological data is used to know the evidence volcano arc and outer-arc ridge. The volcano arc shows that the age is around Quarter which means it is possible for geothermal resources, the outer-arc ridge shows that the rock contents were melange complex and ultramafic rocks.
Sangihe area has possibility for further research as geothermal offshores.
