Sinabung volcanic eruption. Satellite image of the February 2014 ash plume from the Mount Sinabung volcano in North Sumatra, Indonesia. North is at top. Frequent collapses from the unstable lava dome near Sinabung's summit created pyroclastic flows that swept some 4.5 kilometres down the slopes. The flow deposits (light grey) are visible south-east of Sinabung's summit. The ash plume is being blown northwards. The eruption has coated much of the surrounding landscape with ash, causing dark green forests to appear tan. This image was obtained on 6 February 2014 by the Advanced Land Imager (ALI) on NASA's Earth Observing-1 (EO-1) satellite.
