Geological Summary

Cerros de Tocorpuri (or Volcán Tocorpuri) is a stratovolcano complex on the Chile-Bolivia border with a youthful-looking rhyolitic lava dome, Cerro la Torta, at its western foot. The international border swings around the eastern rim of a 1.4-km-wide crater that truncates the summit; the crater lies wholly within Chile. It was considered by González-Ferrán (1995) to be of Pleistocene-Holocene age. Cerro la Torta has been considered to be of Holocene age due to its youthful morphology, but its age is not known precisely and Potassium-Argon dating indicates only that it is less than a million years old. Comparison with similar dated domes nearby suggests it is of Pleistocene age (de Silva, 2007 pers. comm.). The circular, roughly 5 km³ Cerro la Torta was erupted from a central vent and is surrounded by a flat-topped surface with wrinkled flow ridges. The flow terminates in steep, talus-covered margins about 150 m high. Lava extrusion was preceded by minor silicic explosive eruptions.

Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Cerros de Tocorpuri. If this volcano has had large eruptions (VEI >= 4) prior to 12,000 years ago, information might be found on the Cerros de Tocorpuri page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

Photo Gallery

Cerro la Torta, the flat-topped ridge on the horizon, is a Holocene dacitic lava dome on the western side of Cerros de Tocorpuri volcano. Because of its distinctive shape, the dome is referred to locally by the Spanish word for cake (torta). Cerro la Torta, seen here from the west, is a roughly 5 cu km circular dome with a flat surface wrinkled by flow ridges and steep, 150-m-high talus-covered flanks. Emplacement of the 5090-m-high dome began with minor explosive activity, but slow lava extrusion was dominant.

Cerros de Tocorpuri, seen here from the west, is a Pleistocene stratovolcano complex on the Chile-Bolivia border. A Holocene lava dome on its western foot, Cerro la Torta, forms the light-colored ridge at the left foreground. The circular, roughly 5 cu km Cerro la Torta was erupted from a central vent and is surrounded by a flat-topped surface with wrinkled flow ridges. The flow terminates in steep, talus-covered margins about 150-m high. Lava extrusion was preceded by minor silicic explosive eruptions.

The youthful-looking rhyolitic lava dome, Cerro la Torta (left of center), lies at its western foot of Cerros de Tocorpuri (or Volcán Tocorpuri), a stratovolcano complex on the Chile-Bolivia border. The circular, roughly 5 cu km Cerro la Torta has a flat-topped surface with wrinkled flow ridges and terminates in steep, talus-covered margins about 150 m high. The dome has a youthful appearance, but its age is not precisely known. Snow cover in this Landsat view is deep blue.

The Cerro la Torta lava dome formed on the western flank of Cerros de Tocorpuri around 34 ka, shown in this 5 November 2019 Sentinel-2 satellite image (N is at the top). The N-S length of the dome is 4 km with an areal extent of 12 km², and a 4.7 km³ volume. The complex is located along the Chile-Bolivia border.

   Temporal Evolution of Unrest
   Side by Side Volcanoes

WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.

GVMID Data on Volcano Monitoring Infrastructure The Global Volcano Monitoring Infrastructure Database GVMID, is aimed at documenting and improving capabilities of volcano monitoring from the ground and space. GVMID should provide a snapshot and baseline view of the techniques and instrumentation that are in place at various volcanoes, which can be use by volcano observatories as reference to setup new monitoring system or improving networks at a specific volcano. These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments.
