Sara Sara volcano is a glacier-covered stratovolcano in SW Perú, located between Laguna Parinacocha and the Río Ocona. It is the westernmost of Peru's active volcanoes.
the volcano has erupted large andesitic lava flows that extended 10 km eastward into the Río Ocona valle. Relatively undisturbed tephra and lava flow deposits on the upper slope of the volcano suggest that the last activity of volcano was (geologically) recent, and probably less than 10,000 years ago.
