Plume from Manam

On April 28, 2007, Manam Volcano, just off the coast of mainland Papua New Guinea, released a plume of ash and/or steam. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image the same day. This image shows a small, faint plume from the volcano blowing toward the west. Forming an arc around the plume on the eastern side is a small bank of clouds. This image also captures two brownish-green sediment plumes flowing off Papua New Guinea east of Manam.
Manam is a stratovolcano composed of alternating layers of solidified lava, hardened ash, and volcanic rocks. The 10-kilometer- (6-mile-) wide island ranks among Papua New Guinea’s most active volcanoes.
