The major avalanche deposit formed by collapse of the southeastern flank of Kerimasi. This deposit extends from a scarp at an elevation of ∼2000 m approximately 8.9 km in a south-easterly direction to the surrounding Engaruku Basin plains (∼800 m). The flow covers an area of ∼33 km2 and has an average thickness of 30 m. The distal lobe is ∼8 m in thickness at a location known locally as Trig Point Hill.
