Rhyolite lava dome growth styles at Chaitén Volcano, Chile (2008-2009): Interpretation of thermal imagery [PDF]

open access: yesAndean Geology, 2013
Airborne thermal images of the Chaitén rhyolite lava dome were obtained on three occasions between January 2009 and January 2010. These images were useful for understanding the nature and pace of growth of the newly extruded lava, which formed a complex ...

Effects of volcanic and hydrologic processes on forest vegetation: Chaitén Volcano, Chile [PDF]

open access: yesAndean Geology, 2013
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 ...

Overview of Chaitén Volcano, Chile, and its 2008-2009 eruption

open access: yesAndean Geology, 2013
Chaitén Volcano erupted unexpectedly in May 2008 in one of the largest eruptions globally since the 1990s. It was the largest rhyolite eruption since the great eruption of Katmai Volcano in 1912, and the first rhyolite eruption to have at least some of ...

Evidence of mid- to late-Holocene explosive rhyolitic eruptions from Chaitén Volcano, Chile

open access: yesAndean Geology, 2013
The 2008 eruption of Chaitén Volcano was widely cited as the first activity at the volcano for over 9000 years. However, we have identified evidence from proximal pyroclastic deposits for three additional explosive eruptions of Chaitén within the past ...

Late Holocene history of Chaitén Volcano: New evidence for a 17th century eruption

open access: yesAndean Geology, 2013
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.

Rapid ascent of rhyolitic magma at Chaitén volcano, Chile [PDF]

open access: yesNature, 2009
International audienceAlthough rhyolite magma has fuelled some of the Earth's largest explosive volcanic eruptions, our understanding of these events is incomplete due to the previous lack of direct observation of these eruptions.

Pyroclastic density currents associated with the 2008-2009 eruption of Chaitén Volcano (Chile): Forest disturbances, deposits, and dynamics

open access: yesAndean Geology, 2013
Explosive activity at Chaitén Volcano in May 2008 and subsequent dome collapses over the following nine months triggered multiple, small-volume pyroclastic density currents (PDCs).

Entrainment Heat Flux Computed with Lidar and Wavelet Technique in Buenos Aires During Last Chaitén Volcano Eruption

open access: yesEPJ Web of Conferences, 2016
At Lidar Division of CEILAP (CITEDEF-CONICET) a multiwavelength Raman-Rayleigh lidar optimized to measure the atmospheric boundary layer is being operated. This instrument is used for monitoring important aerosol intrusion events in Buenos Aires, such as

Holocene record of large explosive eruptions from Chaitén and Michinmahuida Volcanoes, Chile [PDF]

open access: yesAndean Geology, 2013
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.

Early Vegetation Recovery After the 2008–2009 Explosive Eruption of the Chaitén Volcano, Chile

open access: yesDiversity
In May 2008, Chaitén volcano entered an eruptive process, leading to one of the world’s largest eruptions in recent decades. The magnitude of tephra ejected by the eruption left different types of disturbances and caused diverse forms of environmental ...
