Overview

Gunung Tampomas is an andesitic stratovolcano overlooking the northern coastal plain of western Java about halfway between Tangkubanparahu and Cereme volcanoes. Youthful-looking lava flows are found on its flanks.

Regional Volcanic Activity
The Sunda-Banda Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.
