ملف:2010 Eruption at Mount Merapi, Indonesia (ASTER).jpg

English: This false-color satellite image shows evidence of a large pyroclastic flow along the Gendol River south of Mount Merapi. Light gray volcanic deposits (either from pyroclastic flows or lahars) fill the course of the Gendol. Just north of the Merapi Golf Course (light red feature) is a much wider area where a pyroclastic flow spread across the landscape, causing almost total devastation. Within this dark gray area, most of the trees were knocked down and the ground was coated by ash and rock. The flow deposits are largely surrounded by healthy vegetation, colored bright red. A light gray ash plume extends the west of the volcano, guided by the prevailing winds. Near the plume, heavy ash-fall has coated the fields and forests, coloring them dull red to gray.
