Monte Balbi

Balbi

Estratovolcán · Papua New Guinea · 2715 m

Balbi volcano forms the highest point on Bougainville Island and is part of a large number of coalesced cones and lava domes. Five well-preserved craters occupy a NW-SE-trending ridge N of the summit, which also has a crater. Crater C, containing a small lake, is seen here from the E. A plume from a fumarole field on the W flank of 600-m-wide Crater B is visible to the left. The latest eruption may have been as recent as the mid-19th century.

Resumen geológico

The complex andesitic Balbi stratovolcano on Bougainville Island includes a large number of coalesced cones and lava domes. Five well-preserved craters occupy a NW-SE-trending ridge north of the summit cone, which also contains a crater. Three large valleys with steep headwalls dissect the flanks. The age of the most recent eruption is not known precisely. An oral tradition of a major eruption during the 19th century is thought to be in error, but could refer to minor eruptive activity. Fumaroles are located within 600-m-wide Crater B and on its W flank.

Resumen de Wikipedia

El monte Balbi es un estratovolcán holocénico que se encuentra en la parte norte de la isla de Bougainville, de Papúa Nueva Guinea. Es el punto más alto de la isla con 2715 metros. Hay cinco cráteres volcánicos a lo largo de la cresta norte de la cumbre, uno de los cuales contiene un lago de cráter. Hay muchas fumarolas cerca de los cráteres, aunque Balbi no ha entrado en erupción en los tiempos históricos.
