About Pulosari
Pulosari is a stratovolcano rising to 1,324 meters (4,344 feet) in Indonesia's Sunda-Banda Volcanic Regions. No historical eruptions have been recorded, though the volcano is classified based on geological evidence of past activity.
Geography & Climate
Pulosari is located in Indonesia, within the Sunda Volcanic Arc of the broader Sunda-Banda Volcanic Regions. Situated at 6.34° S, 105.98° E in the Southern Hemisphere, the volcano lies within a tropical climate zone. With a summit elevation of 1,324 meters above sea level, Pulosari is a moderately sized peak that remains accessible to hikers and researchers for much of the year. The volcanic landform is characterized as a composite, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
Geological Context
Pulosari sits in a subduction zone, where one tectonic plate dives beneath another, creating intense heat and pressure that generates magma. Subduction zones are responsible for many of the world's most explosive volcanoes and deadliest eruptions. For communities in Indonesia near Pulosari, this tectonic setting means the volcano is capable of producing powerful explosive eruptions, pyroclastic flows, and lahars that can threaten populated areas within tens of kilometers of the summit. The dominant rock type is andesite / basaltic andesite, a dark, fine-grained volcanic rock that forms from rapidly cooling, low-viscosity lava. Basaltic eruptions tend to be less explosive and produce fluid lava flows that can travel long distances. While less immediately dangerous than explosive eruptions, basaltic lava flows can destroy structures and infrastructure in their path, and volcanic gases released during these eruptions can affect air quality over a wide area.
GVP Reference Summary
The basaltic-to-andesitic Pulosari stratovolcano at the western end of Java lies south of the 15-km-wide Pleistocene Danau caldera. The summit contains a nearly 300-m-deep crater open to the ENE with active solfataras on its wall. It is SW across a low saddle from the higher Karang volcano, which was constructed on the SE rim of Danau caldera.

Frequently Asked Questions About Pulosari
Is Pulosari an active volcano?+
Pulosari is classified as active based on credible evidence of past eruptions. Although its last known eruption was in prehistoric times, volcanologists consider it capable of erupting again.
How high is Pulosari?+
Pulosari has a summit elevation of 1,324 meters (4,344 feet) above sea level. At 1,324 meters, it is a moderately sized volcanic peak, roughly comparable to Mount Vesuvius (1,281m).
What type of volcano is Pulosari?+
Pulosari is classified as a Stratovolcano. Stratovolcanoes (also called composite volcanoes) are steep, conical volcanoes built up by many layers of hardened lava, tephra, and volcanic ash. They are among the most common and dangerous types, known for explosive eruptions.
Where is Pulosari located?+
Pulosari is located in Indonesia, in the Sunda-Banda Volcanic Regions. More specifically, it lies within the Sunda Volcanic Arc. Its exact coordinates are -6.343° latitude, 105.978° longitude.
Is it safe to visit Pulosari?+
Pulosari can generally be visited, but as with any volcano, visitors should check local conditions and any advisory notices before traveling. Indonesia may have specific regulations for accessing volcanic areas. Guided tours are often the safest and most informative way to experience a volcano.
