Kiaraberes-Gagak, seen here from the west, is part of the Perbakti-Gagak volcanic field. The eroded stratovolcano contains numerous fumarolic areas on its flanks. Pumice and obsidian deposits are at the top the volcano and obsidian lava flows extend to the N and NE. Mild phreatic eruptions took place in historical time from flank fumarole fields at the Perbakti-Gagak complex.
