Eruptions du volcan Infiernillo : 6890 BC ± 40 years (radiocarbon dated)
Infiernillo ("little hell") is a young basaltic-andesite volcanic field located along the Río Salado in Argentina about 70 km east of the crest of the Andes and NW of the town of Malargüe, 1000 km distance from Buenos Aires.
Volcanism in the field was caused by extensional tectonics resulting in fissure eruptions that produced lava flows that reached to the river. The last eruption occurred about 9000 years ago at the Volcán Hoyo Colorado vent.
