Victory

Stratovulcano · Papua New Guinea · 1832 m

The forested volcanic massif at the center of the image is Mount Victory, which occupies the lower part of a peninsula SW of Cape Nelson (upper right). To the NE it abuts the deeply dissected Pleistocene Mount Trafalgar volcano, its summit draped by the larger cloud banks. The summit crater of Mount Victory contains a breached crater and several lava domes. The only confirmed historical activity of Mount Victory was a long-term late-19th to early 20th-century eruption that produced pyroclastic flows that reached the coast.

Sintesi geologica

The dominantly andesitic Mount Victory stratovolcano, forming part of Cape Nelson on the NE coast of Papua New Guinea, is covered by rainforest. The deeply dissected Pleistocene Trafalgar volcano is immediately adjacent to the NE. The summit crater is breached to the SE, possibly due to landslides. Several lava domes are present in the summit area. Four small cones are located on the SW side, and two others occur on the NE flank. The only observed activity was a long-term late-19th to early 20th-century eruption that was frequently seen by passing ships. Pyroclastic flows have destroyed several villages and caused fatalities, and reached the coast.
