Volcán Hudson

Hudson, Cerro

Estratovolcán · Chile · 1905 m

The ice-filled 10-km-wide caldera of the remote Cerro Hudson volcano was not recognized until its first 20th-century eruption in 1971. The massive, 1905-m-high Cerro Hudson, seen here from the west on August 23 during its 1991 eruption, covers an area of 300 km2. The caldera is drained through a breach on its NW rim (upper left), which has been the source of mudflows down the Rio de Los Huemules. The 1991 eruption was Chile's second largest of the 20th century, and formed a new 800-m-wide crater in the SW part of the caldera.

Resumen geológico

The ice-filled, 10-km-wide caldera of Cerro Hudson volcano was not recognized until its first 20th-century eruption in 1971. It is the southernmost volcano in the Chilean Andes, related to subduction of the Nazca plate beneath the South American plate. The massive volcano covers an area of 300 km2. The compound caldera is drained through a breach on its NW rim, which has been the source of mudflows down the Río de Los Huemeles. Two cinder cones occur N of the volcano and others occupy the SW and SE flanks. This volcano has been the source of several major Holocene explosive eruptions. An eruption about 6,700 years ago was one of the largest known in the southern Andes during the Holocene; another eruption about 3,600 years ago also produced more than 10 km3 of tephra. An eruption in 1991 formed a new 800-m-wide crater in the SW portion of the caldera.
