"Deviatoric stress inside an oceanic slab after few million years of subduction as simulated by a numerical model assuming a temperature-dependent elasto-visco-plastic rheology. Red regions indicate high flexural stresses mostly at the base of the bended slab (model and figure created by M. Gerbault)."
"Crevasse channels in cross-bedded medium-to coarse-grained sandstone, with conglomerate lags and bearing some vertebrate fossils from the Río Seco de la Quebrada Formation in Quebrada del Durazno, Mendoza, Argentina (Photography by Adriana Mancuso)."
"Panoramic view of the active crater of Planchón-Peteroa volcano. The photo was taken in November 2010, two months after the onset of the eruption. Note the absence of an acid lake and the intense fumarolic activity. View from the W (photo by Daniel Tormey)."
"Agate sample from the Cerro Negro Formation in Cordón de Lila (Permian), Chile. The agates are present in volcanic rocks (rhyodacites/dacites), which undergone late- to post-volcanic hydrothermal alteration (Photography by Jens Götze)."
“Glaciolacustrine sediments cropping-out at "El Canal" stratigraphic trench, which cuts the late-glacial moraine belts nearby Torres del Paine National Park (Chile). The image exposes a mixture of glaciolacustrine sediments including ice rafted debris interlayered with gravels deposited from gentle lake-bottom currents within a high-sedimentary rate subaqueous environment. The cobble in the upper part is a dropstone (Photo by Juan-Luis García).”

"View of Chaitén lava dome looking north on 26 May 2008. At this time, the eruption was undergoing simultaneous explosion and effusion of new lava (on left-central side of dome). See Pallister et al. (this volume) for details. (Photography from J. Marso, United States Geological Survey)"
"Sail Rock is a small volcano located some 35 km southwest of Deception Island. It rises about 30 m above sea level and features a sail-like shape (hence its name). The stack marks the top of a volcano, the rest of which is submerged below sea level. The age of Sail Rock is unknown, and the stack is composed of layers of pyroclastic breccia and tuffs alternating with lava flows. It was not discovered before March 1987 and, as of today, has been visited only twice. (Photography from S. Kraus)"
