Ambae

楯状火山 · Vanuatu · 1496m

Two lakes of variable color lie with the summit caldera of Ambae volcano, as seen in this view from the W. The light blue lake in the foreground is Lake Voui (or Vui), which is enclosed in the crater of a tuff ring within the summit caldera. The dark blue Lake Manaro Lakua lies between the tuff ring and the E caldera wall. Ambae, the most voluminous volcano of the New Hebrides archipelago, forms a 16 x 38 km island. Pentecost Island appears in the background.

地質学的概要

The island of Ambae, also known as Aoba, is a massive 2,500 km3 basaltic shield that is the most voluminous volcano of the New Hebrides archipelago. A pronounced NE-SW-trending rift zone with numerous scoria cones gives the 16 x 38 km island an elongated form. A broad pyroclastic cone containing three crater lakes (Manaro Ngoru, Voui, and Manaro Lakua) is located at the summit within the youngest of at least two nested calderas, the largest of which is 6 km in diameter. That large central edifice is also called Manaro Voui or Lombenben volcano. Post-caldera explosive eruptions formed the summit craters about 360 years ago. A tuff cone was constructed within Lake Voui (or Vui) about 60 years later. The latest known flank eruption, about 300 years ago, destroyed the population of the Nduindui area near the western coast.

Wikipedia の要約

英語版の要約

Manaro Voui, or Manaro Vui, is a shield volcano whose emergent portion is known as the island of Ambae in Vanuatu. The summit is 1,496 metres (4,908 ft) above sea level and about 3,900 m (12,800 ft) above the sea floor. According to indigenous custom Chief Virenaliu Paul Vuhu, the summit's valley and lakes are considered the "sacred place and paradise" where they believe after death, their spirits go to live happily ever after'. The Vanuatu Meteorology and Geohazards Department maintains a live webcam and seismological chart.
