Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Calabozos. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Calabozos page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

Deformation History

There is data available for 1 deformation periods. Expand each entry for additional details.

Deformation during 2010 Feb 27 - 2010 Feb 27 [Subsidence; Observed by InSAR]

Start Date: 2010 Feb 27 Stop Date: 2010 Feb 27 Direction: Subsidence Method: InSAR
Magnitude: 14.000 cm Spatial Extent: 30.00 km Latitude: -35.000 Longitude: -71.000

Remarks: Short-lived subsidence triggered by the Mw 8.8 2010 Maule earthquake

Figure (see Caption)

Volcanic ground subsidence observed in interferogram stacks spanning the earthquake (with earthquake effects removed). We assume the ground displacement is of short duration compared to the interferogram time span, so we compute the stack by summing the interferograms and dividing by the number of measurements in the stack for each pixel.

Photo Gallery

The 26 x 14 km late-Pleistocene Calabozos caldera contains several post-caldera vents of Holocene age. The Descabezado Chico group (mid right-center) was constructed over the buried western rim of the caldera. The Cerro de Medio group (mid extreme-right) grew within the southern part of the caldera. No historical eruptions are known, but hot-spring clusters occur within the caldera.
