Tecuamburro

Stratovolcano · Guatemala · 1845m

Tecuamburro, seen here from the north, is a small lava dome complex of mostly Pleistocene age. The smoother left flank consists of younger lava domes that were constructed during the late Pleistocene or early Holocene within a horseshoe-shaped, east-facing scarp. The scar resulted from structural failure of the older Miraflores edifice (right).

Geological summary

Tecuamburro is a small forested stratovolcano, or large lava-dome complex, about 50 km ESE of Guatemala City and 20 km S of the main volcanic chain. An older andesitic stratovolcano, Miraflores, was formed about 100,000 years ago. Tecuamburro and other lava domes were constructed during the late Pleistocene or early Holocene within an open E-facing scarp produced by structural failure of Miraflores more than 38,000 years ago. One of the largest of these domes, Peña Blanca, overtops the NW rim of the collapse scarp. Two nested craters, the larger of which is Chupadero, lie at the NW end of the complex. The smaller crater is a phreatic tuff ring, Laguna Ixpaco, that was formed about 2,900 years ago during the latest dated eruption of the complex. Numerous fumaroles, hot springs, and boiling mud pots are found in the area around the acidic lake.

From Wikipedia

Tecuamburro is a stratovolcano in southern Guatemala, roughly 50 kilometres south east of Guatemala City. The Tecuamburro is an andesitic stratovolcano which formed approximately 38,000 years ago inside a horseshoe-shaped caldera formed by a structural failure in a second, 100,000-year-old stratovolcano, known as Miraflores. The last eruption is believed to have occurred around 960 BCE. At the top of the Tecuamburro is an acidic crater lake around which many hot springs, fumaroles, and boiling mudpots are found.
