Reventador

Stratovulcano · Ecuador · 3562 m

A steam-and-gas plume rises from the central cone of Reventador volcano in this March 11, 2005 aerial view from the SE. Several lava flows generated during eruptions in 2002 and 2004-2005 are visible on the south and SE flanks of the central cone. The 3562-m-high central cone was constructed within the large 4-km-wide horseshoe-shaped caldera breached to the east (lower right). The caldera was formed during a major collapse of the volcano, which produced a massive debris avalanche that swept into the Amazon basin.

Sintesi geologica

Volcán El Reventador is the most frequently active of a chain of Ecuadorian volcanoes in the Cordillera Real, well east of the principal volcanic axis. The forested, dominantly andesitic stratovolcano has 4-km-wide avalanche scarp open to the E formed by edifice collapse. A young, unvegetated, cone rises from the amphitheater floor to a height comparable to the rim. It has been the source of numerous lava flows as well as explosive eruptions visible from Quito, about 90 km ESE. Frequent lahars in this region of heavy rainfall have left extensive deposits on the scarp slope. The largest recorded eruption took place in 2002, producing a 17-km-high eruption column, pyroclastic flows that traveled up to 8 km, and lava flows from summit and flank vents.
