Geological Summary

The 5-km-wide island of Moti, also known as Motir, is part of a roughly N-S-trending chain of islands off the western coast of Halmahera Island. Moti is located north of Makian volcano and south of Mare and Tidore islands and is surrounded by coral reefs. The truncated, conical island rises to 950 m and contains a crater on its SSW side. Moti was mapped as Holocene in age by Apandi and Sudana (1980). An insignificant eruption was reported in 1774 or shorter before, but Gogarten (1918) indicated that this event was confused with the October 1773 eruption of nearby Gamalama volcano, which could have dropped ash on Moti.
