Licto (Ecuador)

Status Normal Eruption Unknown 3336m
Pyroclastic cone(s) (Subduction zone / Continental crust (> 25 km))

The Licto group of scoria cones lies along the Río Chambo about 25 km SE of the city of Riobamba and just north of the town of Licto. These three basaltic-andesite to andesitic cones form the southernmost area of Quaternary volcanism in the Interandean valley of Ecuador. The basaltic-andesite Cerro Tulabug at 3336 m is the highest of the cones and rises 3 km NW of the town of Licto. Loma Bellavista, 2 km NE of the town, is a 3113-m-high andesitic scoria cone. A third cone, Licto, is of basaltic-andesite composition. The group was considered to be of late-Pleistocene or Holocene age (Hall, 1987, pers. comm; Eissen, 2006, pers. comm.) based on the relatively youthful morphology of the cones.

Cerro Tulabug (right-center), part of the Licto group of basaltic-andesite to andesitic scoria cones, is seen here from the SW. The cones lie along the Río Chambo about 25 km SE of the city of Riobamba and just north of the town of Licto and form the southernmost area of Quaternary volcanism in the Interandean valley of Ecuador. The cloud-draped conical volcano in the left-center background is Reventador, and the Cordillera Real forms the right horizon.
