Caldera del Atuel

Caldera del Atuel is a caldera in Argentina. It is the source of the Rio Atuel and has dimensions of 30 by 45 kilometres (19 mi × 28 mi). Cerro Sosneado is a volcano (best volume estimate 244.2 cubic kilometres (58.6 cu mi)) located outside of the Atuel caldera, Volcan Overo (best volume estimate 89 cubic kilometres (21 cu mi)) and Las Lágrimas complex are located within the caldera.[1][2] Holocene activity may have formed the cinder cones on the northeastern side of the caldera.[3] After the 2010 Maule earthquake, the caldera was one of the volcanic centres that underwent subsidence,[4] along with secondary earthquake activity.[5]
