Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Cordón del Azufre. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Cordón del Azufre 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 1998 - 2011 [Uplift; Observed by InSAR]

Start Date: 1998 Stop Date: 2011 Direction: Uplift Method: InSAR
Magnitude: Unknown Spatial Extent: 40.00 km Latitude: -22.000 Longitude: -68.000

Remarks: Uplift centered at ""Lazufre"" region between Lastarria and Cordon del Azufre volcanoes. Deformation rate accelerated from 2 cm/yr to 3.5 cm/yr from 1998 to 2005, and has been constant from 2005 to 2011.

Figure (see Caption)

Stack of track 282 interferograms showing average LOS uplift at Lazufre between 1995 and 2011. Profiles along the approximate semi-major and semi-minor axis of the surface uplift pattern show the diameter of uplift varies between 50 and 70 km, with no evidence for a moat of subsidence.

Photo Gallery

The volcanic complex in the center of this NASA Landsat composite image is Cordón del Azufre, a small volcanic center straddling the Chile-Argentina border. A dacitic lava-dome complex lies at the eastern side of the complex, in Argentina. The prominent dark-colored lava flow from Volcán la Moyra, the youngest feature of the volcanic field, descended 6 km into Chile and 3 km into Argentina. Lava flows from Bayo volcano to the SW are visible at the lower left.
