Geographical Location and Physical Features
Located in the northern part of Lombok, within the boundaries of the Gunung Rinjani National Park, Mount Rinjani extends across the regencies of North Lombok and East Lombok. It is part of the Lesser Sunda Islands chain, situated in a region characterized by complex tectonic activity. The mountain’s prominent caldera, known as Segara Anak, spans approximately 8 km in diameter and contains a stunning crater lake, making it one of the most captivating natural features in Southeast Asia.
The physical structure of Rinjani is a stratovolcano composed primarily of andesite and basaltic lava flows. Its summit hosts a large volcanic crater with a significant active volcano inside, fumaroles, and hot springs that are clues to ongoing geological activity. The volcano’s slopes are marked by lush forests, alpine meadows, and rugged lava fields that demonstrate its transformative volcanic history. At its pinnacle, Rinjani commands the landscape, visible from great distances and serving as a navigational beacon for locals and visitors alike.
Physical Features

Historical Eruptions and Volcanic Activity
Mount Rinjani’s eruption history is a testament to its geological vitality, with recorded eruptions dating back centuries. Its most notable eruption occurred in 1257, originating from the neighboring volcano of Samalas, which drastically impacted global climate by releasing vast amounts of volcanic ash into the atmosphere. This eruption, considered one of the largest in recorded history, precipitated a “volcanic winter” and significantly influenced medieval global weather patterns.
The volcano has exhibited persistent activity since then, with minor eruptions and fumarolic activity recorded periodically. The last significant eruption took place in 2016, prompting temporary closures of the national park and safety measures for visitors. Such activity underscores the importance of continuous monitoring and the need for travelers to stay informed about current volcanic alerts.
Volcanic Types and Monitoring
