Remote sensing technology was an effective and widely established analytical method for geology and very useful in geothermal exploration, and has proven extremely beneficial and efficiency. Remote sensing methods utilizing the reflection of electromagnetic waves emitted by the sun, the result of reflection is then imaged picture of the Earth’s surface, such as the intrusion of igneous, volcanic, sedimentary rock, fracture zones, geothermal manifestations, etc.

There are two types of remote sensing, namely radar and optical. Both are equally utilize electromagnetic waves captured by the sensor (satellite). On radar remote sensing, image imaged in black and white. While, on the optical remote sensing, image imaged has a variety of colours with their respective bands depending on the type of rock or soil.

By utilizing remote sensing we can minimize the time of exploration, as the result of remote sensing to map the entire area of interest effectively and facilitate the geological survey later.

Not only that, Mr Suwijanto also described the Volcanology, such as studying the various classifications of volcanoes by age, volcanic structure, the geological structure in the area of volcanic and geothermal manifestations.
