Overview

Two cinder cones between Galela Bay and Lake Galela on norther Halmahera, NE of Dukono volcano, were mapped by Supriatna (1980) as basaltic and Holocene. Tarakan Lamo and Tarakan Itji (large and small Tarakan) have well-formed summit craters 800 and 500 m in diameter, and 160 and 125 m deep, respectively.

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.

About the Photo

Two cinder cones with circular craters are located above the center of this NASA Landsat image of northern Halmahera Island (with north to the top). The cones lie between Galela Lake and Galela Bay (upper right), with the town of Galela on its shore. Tarakan Lamo (on the east side of the lake) and Tarakan Itji (to the NW of Tarakan Lamo) have well-formed summit craters 800 and 500 m in diameter and 160 and 125 m deep, respectively.
