Casiri

Casiri, also known as Paucarani, is an about 5,650 metres (18,537 ft) high complex volcano in the Barroso mountain range of the Andes, in the Tacna Region of Peru. It consists of four individual volcanic edifices with lava domes; the southeasternmost edifice has been active during the Holocene, producing thick lava flows that have overrun moraines of Pleistocene age. The youngest lava flow has been dated to 2,600 ± 400 years ago. Although no historical eruptions are known, the volcano is considered to be potentially active and is monitored. The volcano features geothermal manifestations and is linked to a larger geothermal field that has been prospected for geothermal power generation. There are two sulfur mines on the volcano, and the Paucarani reservoir that contains the bulk of Tacna's water supply is associated with Casiri: The Rio Uchusuma that flows through the reservoir originates on the volcano and the reservoir is located on the foot of Casiri.
