Geographical and Geological Overview of Mt. Rinjani
Location and Physical Features
Situated on Lombok Island, within the boundaries of the Gunung Rinjani National Park, Mt. Rinjani spans about 41,330 hectares. Its rugged terrain is characterized by a prominent caldera, which measures roughly 16 km in diameter. At the heart of this caldera lies the Segara Anak Crater Lake, a stunning cobalt-blue body of water filling an active volcanic crater. The mountain’s summit reaches 3,726 meters, commanding panoramic views of the surrounding islands and oceanic landscapes.
Volcanic Formation and Structure
Rinjani is a stratovolcano formed through countless eruptions over millennia, characterized by layers of hardened lava, ash, and volcanic rocks. It belongs to the Sunda Arc, a major volcanic island chain resulting from the subduction of the Indo-Australian Plate beneath the Eurasian Plate. Its ongoing activity is driven by complex tectonic processes, making it a focus area for volcanologists studying volcanic behavior and hazards in Southeast Asia.
