Tata Sabaya is a stratovolcano in Bolivia. It is located at the northern end of the Salar de Coipasa, which lies in the Altiplano. It also lies at eastern end of a line of volcanoes starting with Isluga in the west, and continuing with Cabaray. Its last eruption date is unknown, but it is assigned to the Holocene due to the youthful appearance of the mountain. Tata Sabaya consists of three separate features. At the base lies a pyroclastic shield, topped by lava domes, and finally by a stratovolcano. One of the most spectacular events in the volcano's past was a debris avalanche which covered 300 km to the south of the mountain. Subsequent eruptions have rebuilt the peak to its current appearance. Particularly recent lava flows lie on the western and north-western flanks of the volcano, and the partial collapse of the summit dome has produced deposits on the south-western flank.
A small active fumarole was observed on the summit of Tata Sabaya in 1995.
