Salar de Atacama (Atacama Desert,Antofagasta, Cile)

The Atacama Desert is a plateau located in South America, where ground surface deformation (uplift) was revealed by space-borne InSAR analysis on salt lakes, named Salars. These salars are located at about 4000-5000 m asl, in the Atofagasta region, in a hyperarid desert, one of the driest place on the Earth, and are characterized by saline detritic crust and efflorescences caused by water movement.

The uplift revealed is probably related to the regional decrease of the permafrost elevation, which may contribute to an increase in the annual volume of incoming groundwater.

In that area several flanks of inactive volcanoes show gravitational processes, which might also be related to the decadal diminution of the permafrost elevation.

Supplemental Information
You can customize the template to suit your needs. You can add and remove fields and fill out default information (e.g. contact details). Fields you can not change in the default view may be accessible in the more comprehensive (and more complex) advanced view. You can even use the XML editor to create custom structures, but they have to be validated by the system, so know what you do :-)
