The entire foreground area in this view of Iriga volcano is a massive 1.5 km3 debris avalanche deposit formed by a Holocene landslide. This view from the SE shows the typical hummocky debris avalanche topography. Many of the darker areas are tree-covered hummocks; the irregular topography of the also creates many small ponds.
