Azufral Volcano, Colombia

Azufral stratovolcano in southern Colombia, seen here from the SE, is also known as Azufral de Tuquerres.

It is truncated by a 2.5 x 3 km caldera containing a Holocene lava dome complex.

A crescent-shaped lake, Laguna Verde, occupies the NW side of the caldera.

Nearly a dozen lava domes are present, the latest of which were formed about 3600 years ago and have active fumaroles.

The last known eruption of Azufral volcano took place about 1000 years ago.

Azufral stratovolcano in southern Colombia, also known as Azufral de Tuquerres, is truncated by a 2.5 x 3 km caldera containing a Holocene rhyodacitic lava-dome complex.

A crescent-shaped lake, Laguna Verde, occupies the NW side of the caldera.

Nearly a dozen lava domes are present, the latest of which were formed about 3600 years ago and have active fumaroles.

Azufral rocks are more silicic than those of nearby Colombian volcanoes; an apron of rhyodacitic pyroclastic-flow deposits rings the volcano.

The last known eruption of Volcan Azufral took place about 1000 years ago.
