Research

My main research areas are InSAR geodesy applied to crustal deformation, volcanology (mechanics of magma storage and transport, eruption dynamics, physics-based models of effusive eruptions), active tectonics (crustal earthquakes, volcano-tectonic interactions), and numerical modeling of geologic processes. My geographic areas of research are volcanoes and faults in the Southern and Central Andes, Yellowstone caldera, and Sierra Negra volcano in the Galapagos. I have also collaborated with colleagues in studies of eruptions in Vanuatu. I’ve had the pleasure to visit other great geological places like St Helens, Kilauea and Etna volcanoes, Iceland and the Corinth Rift in Greece.

Volcanology

Hudson volcano, April 2016, an Okmok-like caldera in Southern Chile, it erupted in 1991 in one of the largest eruptions of the XX century.

Active tectonics

Scarp of the Xylokastro normal fault in the Corinth rift, Greece. The flat areas in the fault hanging wall are several uplifted marine terraces. I took the picture from the same place than the picture in Figure 9 of Armijo et al., GJI, 1996.

Numerical and analytic modeling of geologic processes

System of non-homogenenous linear differential equations that predicts the pressure change in two pressurized reservois below Yellowstone caldera.

InSAR geodesy

Comparison of the slant range resolution for C-, and L-band platforms.

Glaciology

Viedma glacier, one of the largest of the Southern Patagonia Icefield

Anthropogenic deformation

Salt crust (brown) and sulphate-carbonate (white) layers of the Salar de Atacama basin.
