PLUTONS is an integrative geophysical, geochemical, and geomorphological study involving researchers from many US, Canadian, South American, and British institutions. The project aims to uncover evidence for active mid-crustal intrusion and crustal formation at Uturuncu and Lazufre volcanoes, located in the central Andes. This region is significant due to its history of large, caldera-forming eruptions.

Researchers are using seismology, magnetotellurics, GPS, InSAR, and gravimetry in order to assess the possibility of another super-eruption and to understand how magma accumulates and erupts in areas of active intrusion and volcanism.

Dr. Matt Pritchard from Cornell University is heading up the GPS and InSAR portions of the PLUTONS project.

UNAVCO Involvement

A permanent, three site CGPS network on Lastarria volcano (Chile) was first established in October of 2010 by UNAVCO. Two of the sites remain active while one was vandalized in early 2011.

In November of 2011 engineer Sarah Doelger returned to Lastarria to replace the stolen CGPS station and help establish a campaign network on and around the volcano.

UNAVCO also supported the installation of a three site CGPS network on and around Uturuncu volcano (Bolivia) in April of 2010.
