Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Caldera del Atuel. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Caldera del Atuel 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: 12.000 cm Spatial Extent: 15.00 km Latitude: -35.000 Longitude: -70.000

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

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

A complex of snow-covered cones (left-center) partially fills the 30 x 45 km wide Caldera del Atuel, which lies just east of the Argentina-Chile border. The headwaters of the Río del Atuel drain to the SE through a wide breach in the caldera rim (top center) in this NASA International Space Station image (with north to the bottom left). The snow-covered Volcán Overo and Sosneado complexes in the eastern part of the caldera contain numerous very youthful basaltic-to-andesitic pyroclastic cones and lava flows.
