Blancas, Lomas (Chile)

Status Unknown Eruption Unknown 2268m
Stratovolcano (Subduction zone / Continental crust (> 25 km))

Volcán Lomas Blancas is a small shield-like stratovolcano of late-Pleistocene to Holocene age (Moreno and Naranjo, 1991) located about 15 km SE of Nevado de Longaví. A 2.3-km-wide caldera, possibly formed by edifice collapse, is open to the SE. The central cone is basaltic. Basaltic-andesite aa lava flows extend 7 km from the collapse scarp. Much of the volcano is covered by pumice deposits that probably originated from Nevado de Longaví.

The small light-brown area at the center of this NASA International Space Station image (with north to the bottom right) is Volcán Lomas Blancas. This small shield-like 2268-m-high stratovolcano of late-Pleistocene to Holocene age is located about 15 km SE of snow-capped Nevado de Longaví volcano (right-center). A 2.3-km-wide caldera, possibly formed by edifice collapse, can been seen opening to the SE. Pumice deposits probably originating from Nevado de Longaví blanket the volcano. The crescent-shaped lake at the upper left is Laguna del Dial.
