Enormous dome central Andes driven huge magma body beneath
2016/11/4
A new analysis of the topography of the central Andes shows the uplifting of the Earth's second highest continental plateau was driven in part by a huge zone of melted rock in the crust, known as a ma...

Seismic hazard assessment Andes earthquake UN/IDNDR South America
2015/9/30
Five Andean countries (Bolivia, Peru, Ecuador, Colombia, Venezuela) and four European countries (Italy, Spain, Holland, Germany) cooperated in the PILOTO program ("Test area for earthquake monitoring ...
Assessment of 21st Century Climate Change Projections in Tropical South America and the Tropical Andes
Climate change Andes Cordillera South America climate models future projections
2014/11/4
The tropical Andes are one of the regions where climate change has been most evident. This is consistent with the notion that tropical high-elevation mountains will be more affected by warming. One of...

The tropical Andes are one of the regions where climate change has been most evident. This is consistent with the notion that tropical high-elevation mountains will be more affected by warming. One of...
Scientists have long been trying to understand how the Andes and other broad, high-elevation mountain ranges were formed. New research by Carmala Garzione, a professor of earth and environmental scien...
Boron and other trace element constraints on the slab-derived component in Quaternary volcanic rocks from the Southern Volcanic Zone of the Andes
Andean Arc arc lava boron prompt γ-ray analysis mantle source
2017/4/11
We present a dataset for boron and other trace element contents obtained from samples from 13 volcanoes distributed
along the Quaternary volcanic front of the Southern Volcanic Zone (SVZ) of the Chil...
Interseismic coupling and seismic potential along the Central Andes subduction zone
Interseismic coupling seismic potential along the Central Andes subduction zone
2014/4/15
We use about two decades of geodetic measurements to characterize interseismic strain build up along the Central Andes subduction zone from Lima, Peru, to Antofagasta, Chile. These measurements are mo...
Recent variation of the Las Vacas Glacier Mt. Aconcagua region, Central Andes, Argentina, based on ASTER stereoscopic images
Las Vacas Glacier Mt. Aconcagua region Central Andes ASTER stereoscopic images
