Overview

Gunung Tobaru, also known as Lolodai, is located in northern Halmahera WSW of Dukono and NNE of Ibu. Supriatna (1980) mapped the little known andesitic volcano as Holocene.

Regional Volcanic Activity
The Western Pacific 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.
