Context
Seram is a large island in Indonesia's Maluku province. On the coast of Desa Iha, in the Huamual district of West Seram Regency, lies the hamlet of Hulung. Its beach sits at the foot of Gunung Tembaga, near a cinnabar mine, about 20 minutes by motorbike from the village. In early May 2017, fishermen had watched something floating offshore near Iha for several days. They took it for a damaged boat.
