Caldera · Papua New Guinea · 724 m

Recently-emplaced lava flows are seen along a SSE line of vents leading towards the summit of Pago in this 16 September 2002 view. The Pago cone that was constructed within the 5.5 x 7.5 km Witori caldera, which formed around 3,300 years ago. Since its formation a few hundred years ago the cone has grown to a height above the caldera rim. A series of ten lava flows, one of which underlies the area of scorched vegetation left of the 2002 lava flows, cover much of the caldera floor.

Resumen geológico

The active Pago cone has grown within the Witori caldera (5.5 x 7.5 km) on the northern coast of central New Britain contains the active Pago cone. The gently sloping outer caldera flanks consist primarily of dacitic pyroclastic-flow and airfall deposits produced during a series of five major explosive eruptions from about 5,600 to 1,200 years ago, many of which may have been associated with caldera formation. Pago cone may have formed less than 350 years ago; it has grown to a height above the caldera rim, and a series of ten dacitic lava flows from it covers much of the caldera floor. The youngest of these was erupted during 2002-2003 from vents extending from the summit nearly to the NW caldera wall. The Buru caldera cuts the SW flank.
