Gunung Penanggungan, seen here from Tengger caldera to its east, was constructed immediately north of the Arjuno-Welirang massif with its flanks forming the ridge at the left. Lava flows from flank vents give the volcano an irregular profile. Lava flows have descended all flanks of the volcano and pyroclastic flow deposits form an apron around it.
