Details for: Witori
Freshly emplaced, steaming lava flows trend SSE towards the summit of Pago volcano in this September 16, 2002 view. Pago is a young post-caldera cone that was constructed within the 5.5 x 7.5 km Witori caldera, which formed about 3300 years ago. Since its formation a few hundred years ago, Pago has grown to a height above that of the Witori caldera rim. A series of ten dacitic lava flows from Pago, one of which underlies the area of scorched vegetation left of the 2002 lava flows, covers much of the caldera floor.
