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.
