The measurement of 2D geo-electrical using Wenner Alpha configuration was conducted in the shore line of northern part of Ternate island, in order to know the depth of interface and to analyze the aquifers in conjunction with estimation of ground water potential. Water quality analysis is also conducted in some dug wells, such as in situ water temperature, electrical conductivity, pH, turbidity, dissolved oxygen, and salinity.Due to laboratory analysis, the values of measured parameters of water quality from some dug wells meets to the standards referred, especially for drinking water. The result of interpretation from geo-electrical data showed the depth of interface less than 10m.  From a drilled well data near shore line, indicate about 5m deep of interface. Base on geo-electrical survey, water quality analysis and field observation can be concluded that Ternate Island has limited potential of ground water, especially related to amount of fresh ground water. Which is now days, no alternative source yet of clean water for domestic use.

The geological condition of Morotai Island is influenced by small faults and tectonic activity from several major and minor plates that form the subduction zone, are the Pacific plate, the Philippine plate, the Sangihe plate, and the Moluccas Sea plate. This causes Morotai Island to have a high potential for earthquake hazards. South Morotai is the center of government, services, trade and economy on Morotai Island, and has a high potential for earthquakes. Therefore, an analysis of the distribution of seismic vulnerability values ​​in South Morotai was carried out based on mapping as a disaster mitigation effort in South Morotai. The microtremor method uses the H/V spectral ratio analysis technique to analyze the level of earthquake hazard based on the value of the seismic vulnerability index by considering local soil conditions. The ground frequency value (f0) obtained when measuring microtremor is between 0.6 Hz to 0.7 Hz. The amplitude value (A0) in the South Morotai area is around 1.9 – 5.2 times strengthening. The value of the seismic susceptibility index (Kg) in the study area is calculated based on the value of the basic frequency and amplitude with between 5.9 to 44.8. It was concluded that the distribution of a high Kg index and an earthquake prone area was in Darame Village, Muhajirin Village, and Wawama Village with a Kg value > 20. This area is composed of alluvium consisting of gravel, potential mud, and boulders, so it is classified into soft soil type. Less vulnerable areas are in Gotalamo Village, Daruba Pantai Village, and Darame Village
