Abstract: In this paper we report the continuation of previous observation of hot spring phenomenon in northern Ternate island. The hot spring distribution spread unevenly with temperature ranging from 29 °C to 35.5 °C along shore line. Geomagnetic measurements, chemical water and physical water properties have been carried out to find the caused of unevenly hot spring distribution . This research intends to reveal geothermal potential in a small volcanic island. The result of geomagnetic measurements, showed low magnetic anomalies as demagnetization rock by heat. Magnetic anomaly map shown any fault structure alignment with the northeast – southwest. The fault structures create path of heat. The result of chemical and physical water properties also agree with geomagnetic measurement that show indication of geothermal system. The heat source comes from magma chamber and passes through rock fractures (fault) as known as up flow geothermal system.
