Manam

성층화산 · Papua New Guinea · 1807m

The 10-km-wide island of Manam is one of Papua New Guinea's most active volcanoes. Four large radial valleys extend from the unvegetated summit to its lower flanks and two summit craters are present. Most eruptions during the past century have originated from the southern crater, concentrating eruptive products into the SE avalanche valley, seen here from off the east coast of the island. Frequent eruptions have been recorded since 1616.

지질학적 요약

The 10-km-wide island of Manam, lying 13 km off the northern coast of mainland Papua New Guinea, is one of the country's most active volcanoes. Four large radial valleys extend from the unvegetated summit of the conical basaltic-andesitic stratovolcano to its lower flanks. These valleys channel lava flows and pyroclastic avalanches that have sometimes reached the coast. Five small satellitic centers are located near the island's shoreline on the northern, southern, and western sides. Two summit craters are present; both are active, although most observed eruptions have originated from the southern crater, concentrating eruptive products during much of the past century into the SE valley. Frequent eruptions, typically of mild-to-moderate scale, have been recorded since 1616. Occasional larger eruptions have produced pyroclastic flows and lava flows that reached flat-lying coastal areas and entered the sea, sometimes impacting populated areas.

Wikipedia 요약

영어 요약

Manam, known locally as Manam Motu, is an island located in the Bismarck Sea across the Stephan Strait from Yawar on the northeast coast of mainland Papua New Guinea's Bogia District. The island is 10 kilometers (6.2 mi) wide, and was created by the activity of the Manam Volcano, one of the country’s most active. The island was evacuated in 2004 and its residents resettled elsewhere in Papua New Guinea, but many have begun to return despite concerns of future volcanic activity. Manam is still erupting as of January 2024.
