Photo Gallery

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).

Tecuamburro, seen here from the SE on the Pacific coastal plain, is a small lava-dome complex of mostly Pleistocene age. Tecuamburro and other lava domes forming the right-hand peaks were constructed during the late Pleistocene or early Holocene within a horseshoe-shaped, east-facing crater. The crater resulted from structural failure of the older Miraflores stratovolcano on the left.

The low ridge on the left-hand horizon is the southern rim of a large horseshoe-shaped crater left by collapse of Miraflores, an ancestral edifice of the Tecuamburro volcanic complex. Miraflores formed about 100,000 years ago and collapsed sometime prior to 38,000 years ago. The vegetated peak to the right is part of the Tecuamburro lava dome complex, which formed within the scarp.

The summit lava dome complex of Tecuamburro is seen here from the NE along the road from Cuilapa. Four adjacent NW-SE-trending lava domes, the SE-most (left-center) of which is Tecuamburro proper, were erupted within a large horseshoe-shaped scar left by collapse of an ancestral edifice. These domes erupted less than 38,000 years ago. The Tecuamburro complex was constructed within a 20-km-wide graben whose northern margin terminates against the major regional Jalpatagua fault.

Ixpaco crater is a 1-km-wide maar on the NW flank of Tecuamburro that formed during an explosive eruption about 2,900 years ago. An acidic lake fills the maar, and fumaroles, acid-sulfate hot springs, and mud pools occur around the lake. Colloidal sulfur turns the lake a milky green color. This view is from the north with the forested lava domes of Cerro Miraflores (left) and Cerro Pena Blanca (right) in the background.

The deeply eroded Plio-Pleistocene stratovolcano at the upper right is Pueblo Nuevo Viñas (also known as Cerro la Gabia). Four scoria cones are located on the NE flank, and lava flows from the volcano cover the western portion of the Cuilapa quadrangle. This view is from the NW at the summit of Pacaya volcano with Tecuamburro volcano on the center horizon. Flank activity from Tecuamburro has occurred as recently as about 3,000 years ago.

Four large Pleistocene volcanic complexes are visible in this Landsat image of southern Guatemala, with the Pacific coastal plain at the bottom. Minor activity at Tecuamburro volcano continued into the Holocene at Laguna Ixpaco, the small circular white dot a little more than half-way between the Tecuamburro and Piedra Grande labels. The Río los Esclavos extends from the upper right, cutting between Tecuamburro and Ixhuatán volcanoes.

The Tecuamburro volcanic complex has a diverse history. Collapse of the ancestral Pleistocene Miraflores edifice underwent collapse, producing an avalanche deposit that traveled across the Río los Esclavos (right) and forming a large horseshoe-shaped crater open to the east. The modern Tecuamburro complex, consisting of four lava domes, was constructed within this scarp. The Laguna Ixpaco crater was created about 2,900 years ago within the much larger Pleistocene Chupadero crater.
