Analysis of Lateral Heat Flow of Surface Geothermal Manifestation Based on Temperature Distribution in Pine Forest Park, Tomohon North Sulawesi

Abstract

The presence of geothermal energy resource subsurface is reflected on the surface by the appearance of geothermal manifestation, i.e. hot spring, hot mud, fumaroles, etc. Existence of surface geothermal manifestation occurred as consequence thermal propagation from subsurface by fractures as geothermal fluid medium to surface. This research describes the surface temperature distribution to know lateral heat flow direction of surface geothermal manifestation based on temporal and spatial analysis at pine forest park, Tomohon North Sulawesi. This research using the remote sensing methods with thermal infrared channel recorded in years 2013, 2014, and 2015. The result of research shows that thermal anomaly, and lateral heat flow direction of geothermal manifestation at pine forest park trend toward northeast
