May 8, 2014 - Plume from Dukono, Halmahera, Indonesia
On April 28, 2014 NASA’s Terra satellite passed over Indonesia as the Dukono Volcano was emitting a large ash plume. The Moderate Resolution Imaging Spectroradiometer (MODIS) flying aboard captured this true-color image of the volcanic activity at 1:45 UTC (10:45 a.m. local time). The ash rises from the tan-colored cone of Dukono on Helmahara Island, and blows to the east across the Halmahera Sea.
This remote volcano has been in semi-permanent eruption from at least 1933 until present. More-or-less continuous explosions and ash plumes are reported, sometimes accompanied by lava flows. Dukono has been in a particularly active phase since 2003 and in recent months ash plumes have been emitted almost daily, often reaching 8,000 feet (2.4 km), according to the Vo
lcano Discovery website.
Dukono is a complex volcano, with multiple summit peaks and overlapping craters. It is one of 78 historically active volcanoes in the Indonesia archipelago.
