Tata Sabaya, Stratovolcano summit in Western Cordillera, Bolivia

Tata Sabaya is a stratovolcano in the Western Cordillera that rises 5,430 meters above sea level. Its slopes show five distinct lava flows extending up to 2 kilometers from the summit.

The volcano experienced a major collapse of its southern flank around 12,000 years ago. This event deposited 6 cubic kilometers of material into what was then Lake Coipasa.

The name Tata Sabaya means "Father Sabaya"; "Sabaya" may be an Aymara corruption of the Quechua word for "devil" or "demon". A sanctuary stands on the summit, and local myths personify the volcano. A ritual links it with neighbouring volcanoes, and the village of Pagador lies west-southwest of the mountain.

The summit sanctuary and the collapse scarps lie above 5,000 m, reached from the village of Pagador west-southwest of the edifice; the surrounding region is thinly inhabited, so carry all supplies. The dry climate keeps the Salar de Coipasa plain visible from the upper slopes.

The collapse deposit south of the volcano, 20 km long and 7 km wide, was first taken for a pyroclastic flow deposit; it is a landslide that carried material from the salar and was identified even on low-resolution Landsat images. Its hummocks shrink with distance from the edifice.
