Ticsani is a complex of 3 dacitic lava domes in southern Peru in the Ichuna district across the Río Tambo about 30 km SE of Huaynaputina volcano. The volcano has a youthful appearance and is not covered by glaciers. There are no historical eruptions known from Ticsani, a pumice layer from the crater that contains the youngest lava dome overlies the ash from the 1600 AD Huaynaputina eruption and therefore must be younger. At present, there is fumarolic activity.

Both Ticsani and Huaynaputina volcanoes lie about 50 km behind the main volcanic arc of the Peruvian Andes.

A young lava field is found at the NW base of the volcano. A major debris avalanche produced by tectonic collapse entered and partially filled the Río Tambor valley to the south.
