Journal Article: Philippine Geothermal Resources- General Geological Setting And Development

The Philippine Archipelago has a composite geologic structure arising from the multi-stage development of volcanic-tectonic events evidenced by volcanism and seismic activity occurring along the active blocks of the major structural lines which traverse most of the major islands of the Philippines. The widespread volcanic activity located along the active tectonic blocks has generated regions of high heat flow, where a vast number of potentially rich geothermal resources could be exploited as an alternative source of energy. As part of a systematic geothermal development program launched by the Philippine government after the successful pilot study at the Tiwi geothermal field in 1967 by the Commission on Volcanology (now called the Philippine Institute of Volcanology-PIV), the Philippines developed four geothermal fields in the period 1972-1984. These four areas, Tiwi in Albay, Mak-Ban in Laguna, Tongonan in Leyte, and Palinpinon in Southern Negros, have already contributed 891 MW installed capacity to the total electrical power supply of the country, which is mainly dependent on oil resources. The Philippines envisaged that, with its accelerated geothermal energy programme, it would be able to achieve its target of reducing the country's dependence on imported fossil fuel by about 20% within the next decade through the utilization of its vast geothermal energy resources.
