The present day geology of the Molucca Sea region contains a record of the stages in the collision between two arcs. Observations offshore and on land in the Halmahera islands can be used to infer the sequence and timing of events which created the double subduction system and the now complete subduction of the Molucca Sea Plate. In the northern Molucca Sea the Halmahera Arc has been entirely overridden by the Sangihe Forearc and it seems probable that in a few million years time the entire Halmahera Arc will have disappeared with almost no trace.
