The symmetrical Tata Sabaya stratovolcano towers above the northern end of the Salar de Coipasa in the Altiplano of Bolivia. A pyroclastic shield capped by lava domes was topped by effusive eruptions that formed an unglaciated andesitic stratovolcano. Collapse of this edifice produced a large late-Pleistocene debris avalanche that swept into the Salar de Coipasa and covered an area of more than 300 sq km south of the volcano, traveling up to 30 km. Tufa deposits on avalanche hummocks in the Salar de Coipasa correspond to a ca. 12,000 year old high stand of the lake. Renewed eruptions during the Holocene constructed lava domes and flows that have restored much of the original edifice, producing the present-day stratovolcano, whose summit is formed by a 5430-m-high lava dome. Youthful lava flows extend down the NW and western flanks of the volcano, and pyroclastic-flow deposits from partial collapse of the summit dome extend to the lower SW flank.
The Global Volcanism Program is not aware of any Holocene eruptions from Tata Sabaya. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Tata Sabaya page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
The Global Volcanism Program has no synonyms or subfeatures listed for Tata Sabaya.
|Symmetrical Tata Sabaya stratovolcano towers to the north above the village of Pagador in the Altiplano of Bolivia. Thick dacitic lava flows at the left partially cover a scarp from a major collapse of the edifice that produced a large debris avalanche which swept into the Salar de Coipasa, covering an area of more than 300 sq km south of the volcano. The morphology of the volcano has been subsequently modified by dome emplacement (left and right) and hot avalanches.

|A long E-W-trending volcanic chain extends across the border between Chile and Bolivia in this NASA Space Shuttle image (with north to the upper right). The chain extends from historically active Isluga volcano (upper left) to eroded Saxani volcano at the lower right. The smaller volcano immediately to the west of Saxani with a sharp shadow is the steep-sided Tata Sabaya volcano. Tata Sabaya was the source of a major debris-avalanche deposit (bottom center) that forms the small dark-colored hills on the white floor of Salar de Coipasa.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
