Volcán Antisana

Antisana

Estratovolcán · Ecuador · 5753 m

Antisana is a massive, glacier-covered stratovolcano NE of Cotopaxi. The 1.4 x 1.8 km summit crater, seen here from the north, is breached to the SE. Viscous, youthful block lava flows have issued from radial fissures on the flanks of 5753-m-high Antisana. The only unequivocal historical eruption took place from 1801 to 1802. Eighteenth-century eruptions occurred NW of Antisana within Chacana caldera, which lies beneath the cloud bank in the foreground.

Resumen geológico

Antisana is a massive, glacier-covered stratovolcano NE of Cotopaxi, along the western margin of the Eastern Cordillera, 50 km SE of Quito. An older edifice forming the east side of the volcano was constructed over granitic and metasedimentary rocks and is itself overtopped on its NW side by the current edifice. Viscous lava flows have issued from radial fissures on the flanks. A lava flow was erupted from a vent NNE of the summit during 1801-1802.
