caption_attribution_description: English: Bright white clouds hover over the volcano’s summit. Clouds often collect over peaks, but these clouds could result from water vapour released by the volcano. Slightly darker in colour, a pale blue-grey plume blows west-north-west from the summit and over the Bismarck Sea. Just 10 kilometres across, Manam is a stratovolcano composed of alternating layers of ash, lava, and rocks from prior eruptions. The circular island sports four radial valleys spaced roughly 90 degrees apart, and these valleys have historically channelled lava and pyroclastic flows—composed of hot rock, gas and ash—sometimes all the way to the coast. Evidence of earlier volcanic activity appears as rivulets of rock that interrupt the vegetation coating much of the island. Although clouds hide the summit in this image, the summit is known to support two craters devoid of vegetation.
context_page_description: 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 wide, and was created by the activity of the Manam Volcano, one of the country’s most active. It 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.
