Photo Gallery

This view from the summit of Ternate Island shows the Halmahera Island volcanoes of Jailolo in the foreground, Gamkonora on the left, and flat-topped Ibu volcano on the right. Jailolo volcano has no known historical eruptions, but youthful lava flows are located on the eastern flank. Gamkonora is one of Halmahera's most active volcanoes, while Ibu, with its nested summit craters, one of which has a crater lake, has erupted only once in historical time, in 1911.

Three Halmahera Island volcanoes are visible in this view from the SW at the summit of Gamalama volcano on Ternate Island. The twin caldera complex of Todoku-Ranu is on the left, the historically active volcano of Gamkonora is on the skyline at the right center, and Jailolo volcano rises above the clouds at the lower right. These volcanoes are part of a N-S chain extending along the western coast of northern Halmahera Island.

The Jailolo volcanic complex (center) forms a roughly 10-km-long peninsula west of Jailolo Bay (bottom-right) in this NASA Landsat image (with north to the top). Jailolo stratovolcano in the center of the complex is flanked by small calderas to the west and SW. Kailupa cone forms the east side of the small island off the southern coast of the peninsula. Hot mudflows were reported from Jailolo volcano shortly prior to 1883, but no eruptions are known during historical time.

The Jailolo volcanic complex forms a roughly 10-km-long peninsula on West Halmahera Island, seen in this 13 September 2019 Sentinel-2 satellite image. The Jailolo cone forms the center of the peninsula, and the 2-km-diameter Idamdehe caldera is to the W. To the S of the caldera are Bobo crater and Pajo and Saria (or Kailupa hill) cones.
