Evidence of volcaniclastic sedimentation occurs in the first depositional sequence of the sedimentary succession of the Amantea Basin. Volcaniclastic deposits are intercalated in the upper part of a sandstone formation and these show a maximum thickness ...

Planchón-Peteroa volcano started a renewed eruptive period between January 2010 and July 2011. This
eruptive period was characterized by the occurrence of 4 explosive eruptive phases, dominated by low-intensity phreatic
activity, which produced almost pe...

Tephra fall deposits and one large ignimbrite close to Chaitén and Michinmahuida Volcanoes were analyzed for chemistry and radiocarbon dated to correlate the eruptive units and establish the timing of eruptions. These data suggest that both volcanoes wer...
