Volcán Cerro Machín

Machin

Stratovolcano · Colombia · 2749m

Two central lava domes of Cerro Machín volcano are seen here from the SW. A 3-km-wide caldera, whose rim is the horizontal change in slope across the center of the photo, opens towards the south. Late-Holocene eruptions produced block-and-ash flows that traveled to the west and south, beyond the caldera. Deposits from some of these eruptions form the eroded slopes in the lower part of the photo along the valley of the Toche River.

Geological summary

The small Cerro Machín stratovolcano lies at the southern end of the Ruiz-Tolima massif about 20 km WNW of the city of Ibagué. A 3-km-wide caldera is breached to the south and contains three forested dacitic lava domes. Voluminous pyroclastic flows traveled up to 40 km away during eruptions in the mid-to-late Holocene, perhaps associated with formation of the caldera. Late-Holocene eruptions produced dacitic block-and-ash flows that traveled through the breach in the caldera rim to the west and south. The latest known eruption of took place about 800 years ago.

From Wikipedia

Cerro Machín is a stratovolcano located in Tolima Department, Colombia. Considered the most dangerous active volcano of Colombia, Cerro Machin is a volcanic plug that is approximately the same age as the Ruiz-Tolima Massif and has the appearance of being part of that volcanic system.
