Cerro Torta is a dacitic lava dome in Argentina.

Approximately 600 metres (2,000 ft) high, it covers an area of 14 square kilometres (5.4 sq mi) with 2.8 cubic kilometres (0.67 cu mi) of rocks.

[2] A seismic swarm recorded on the 23 January 2009 at Cerro Torta most likely reflects underground movement of magma, but a source in tectonic faulting close to the dome is also possible.

[4] The dome lies in the Central Volcanic Zone of the Andes,[5] in the Ojos del Salado region.

Peinado and several mafic monogenetic volcanoes form an alignment with Cerro Torta.
