Jailolo volcan

Jailolo stratovolcano is in the center of a volcanic complex forming a peninsula west of Jailolo Bay on the western coast of Halmahera Island. Jailolo stratovolcano has not erupted in historic times, but there are young lava flows on the eastern flank.

Introduction:

Small calderas exist on the SW side of the volcano. The westernmost caldera, Idamdehe, cuts an older volcanic edifice preceding Jailolo. There are hot springs on the NW coast of the caldera and hot mudflows were reported shortly before 1883. Another part of the volcanic edifice, Kailupa cone forms a small volcanic island off the southern coast of the peninsula.
