Situated 13 km off the northwestern coast of PNG's Madang Province and lying 54 km southeast from the mouth of the Sepik River (see November 2004 image at right) is the steep-sided volcanic cone that forms the island of Manam (also known as Manum). The volcano is one of the most active in Papua New Guinea with activity being recorded nearly every year.
The island is circular in shape, measuring 10 km across, with its 1,807 m high summit dramatically cut by four large avalanche valleys that descend radially from the summit (two of these are clearly seen in the large size image). The valleys are cliff-lined, rugged and devoid of vegetation and serve to channel lava and pyroclastic flows down the flanks of the volcano. Brown-coloured lava flows which have used these channels to reach the coast are also easily discernible in the image. At the summit are two active craters, with the southern crater being the historically most active.
