The Tungurahua volcano (Northern Andean Volcanic Zone) has been erupting since 1999, with at least
four eruptive phases up to present. Although a dozen of research focuses in tephra fall deposits during this period, none
of them cover the full eruptive c...

Sediment cores from lakes and bogs in the Río Cisnes valley contain tephra from explosive eruptions of
volcanoes in the southern part of the Andean Southern Volcanic Zone (SSVZ). These tephra, which thicken and coarsen
to the west, are attributed to erup...

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...

Prior to May 2008, it was thought that the last eruption of Chaitén Volcano occurred more than 5,000 years ago, a rather long quiescent period for a volcano in such an active arc segment. However, increasingly more Holocene eruptions are being identified...

The 2008-2009 eruption of Chaitén Volcano (Chile) involved a variety of volcanic and associated hydrologic processes that damaged nearby forests. These processes included coarse (gravel) and fine (silt to sand) tephra fall, a laterally directed blast, fl...
