SummaryWe propose to collect TSX data suitable for InSAR time series at 4 volcanoes and geothermal areas in the central and southern Andes to monitor surface deformation. Two of these volcanoes (called Uturuncu, Bolivia and Lazufre on the Chile-Argentina border) are the focus of a 5 year project called PLUTONS funded by the US National Science Foundation and the UK National Environmental Research Council. Two of the other targets are in southern Chile: Laguna del Maule and Cordon Caulle (which has been erupting since 6 June 2011 until the present) and are part of a project funded by the US National Aeronautics and Space Administration. Observations for the 2 targets in the southern Andes will only be made in the austral summer (approximately November-March) while the 2 volcanoes in the central Andes that are part of the PLUTONS project can be made year around. The TSX observations will be compared with ground observations and earlier InSAR observations collected by ERS, Envisat, and ALOS. Each of the areas have known surface displacement at rates of 1-20 cm/yr and encompas areas of different size -- from the largest at Uturuncu with a diameter of about 150 km to the smallest at Laguna del Maule with a diameter of about 40 km.
