The Jailolo volcanic complex forms a peninsula west of Jailolo Bay on the western coast of Halmahera Island. Jailolo stratovolcano at the center of the complex has youthful lava flows on its eastern flank. Small calderas are located west and SW of Jailolo. The westernmost caldera, Idamdehe, truncates an older twin volcano of Jailolo. Hot springs occur along the NW coast of the caldera. Kailupa cone forms a small volcanic 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 Global Volcanism Program is not aware of any Holocene eruptions from Jailolo. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Jailolo page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

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 following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
