Ulawun

Estratovolcán · Papua New Guinea · 2334 m

The symmetrical Ulawun is one of Papua New Guinea's most frequently active volcanoes. Ulawun and Bamus volcano (upper left) are the two highest volcanoes of the Bismarck Archipelago, and are known as the Father and South Son volcanoes, respectively. The upper 1,000 m of Ulawun is unvegetated. Historical eruptions date back to the beginning of the 18th century.

Resumen geológico

The symmetrical basaltic-to-andesitic Ulawun stratovolcano is the highest volcano of the Bismarck arc, and one of Papua New Guinea's most frequently active. The volcano, also known as the Father, rises above the N coast of the island of New Britain across a low saddle NE of Bamus volcano, the South Son. The upper 1,000 m is unvegetated. A prominent E-W escarpment on the south may be the result of large-scale slumping. Satellitic cones occupy the NW and E flanks. A steep-walled valley cuts the NW side, and a flank lava-flow complex lies to the south of this valley. Historical eruptions date back to the beginning of the 18th century. Twentieth-century eruptions were mildly explosive until 1967, but after 1970 several larger eruptions produced lava flows and basaltic pyroclastic flows, greatly modifying the summit crater.

Resumen de Wikipedia
