English: Satellite image of Volcan Villarrica. The 2,582-meter stratovolcano is mantled by a 30-square-kilometre glacier field, most of it amassed south and east of the summit in a basin made by a caldera depression. To the east and north-east, the glacier is covered by ash and other volcanic debris, giving it a rumpled, brown look. The western slopes are streaked with innumerable grey-brown gullies, the paths of lava and mudflows (lahars). Beyond the reach of ash and debris deposits, the volcano is surrounded by forests; the area is a national park. Lago Villarrica is visible to the north-west and Lago Calafquéen is visible to the south-west (lower left).
