Geological summary
Ticsani is a dacitic lava dome complex in the Ichuna district of Peru, about 30 km SE of Huaynaputina volcano. Volcán Ticsani resembles Huaynaputina in its dacitic composition and explosive eruptive style. Both lie about 50 km behind the main volcanic front of the Peruvian Andes. A fresh-looking lava field lies at the NW base of the youthful-looking, unglaciated edifice. A major debris avalanche partially filled the Río Tambo to the south. Emplacement of three lava domes since the end of the Pleistocene was accompanied by explosive eruptions. No historical eruptions are known, but fumarolic activity continues, and pumice from the crater containing the youngest lava dome overlies tephra from the 1600 CE Huaynaputina eruption.
From Wikipedia
Ticsani is a volcano in Peru northeast of Moquegua and consists of two volcanoes that form a complex. "Old Ticsani" is a compound volcano that underwent a large collapse in the past and shed 15–30 cubic kilometres (3.6–7.2 cu mi) of mass down the Rio Tambo valley. Today an arcuate ridge remains of this edifice. "Modern Ticsani" is a complex of three lava domes which were emplaced during the Holocene. Two large eruptions took place during the Holocene, producing the so-called "Grey Ticsani" and "Brown Ticsani" deposits; the last eruption occurred after the 1600 eruption of neighbouring Huaynaputina. The volcano is seismically active and features active hot springs and fumaroles; since 2015 the volcano is monitored by the Peruvian government.
