Event Trees and Epistemic Uncertainty in Long‐Term Volcanic Hazard Assessment of Rift Volcanoes: The Example of Aluto (Central Ethiopia)

Geochemistry, Geophysics, Geosystems, Volume 21, Issue 10, October 2020., 2020
Abstract Aluto is a peralkaline rhyolitic caldera located in a highly populated area in central Ethiopia. Its postcaldera eruptive activity has mainly consisted of self‐similar, pumice‐cone‐building eruptions of varying size and vent location. These eruptions are explosive, generating hazardous phenomena that could impact proximal to distal areas from ...

Acute sedimentation response to rainfall following the explosive phase of the 2008–2009 eruption of Chaitén volcano, Chile

Bulletin of Volcanology, 2013
The 10-day explosive phase at the start of the 2008–2009 eruption of Chaitén volcano in southern Chile (42.83°S, 72.65°W) blanketed the steep, rain-forest-cloaked, 77-km2 Chaitén River drainage basin with 3 to >100 cm of tephra; predominantly fine to ...

Total devastation of river macroinvertebrates following a volcanic eruption in southern Chile

Ecosphere, Volume 11, Issue 5, May 2020., 2020
Abstract Although explosive volcanic eruptions are natural disturbances that cause significant environmental repercussions and impose multiple changes on ecosystems, post‐eruption studies of rivers and streams are not common. The most recent eruption of the Puyehue‐Cordón Caulle volcanic complex (PCCVC) began on 4 June 2011 with a large explosion and ...

Volcanic ash leaching as a means of tracing the environmental impact of the 2011 Grímsvötn eruption, Iceland [PDF]

, 2016
The Grímsvötn volcanic eruption, from 21 to 28 May, 2011, was the largest eruption of the Grímsvötn Volcanic System since 1873, with a Volcanic Explosivity Index (VEI) of magnitude 4. The main geochemical features of the potential environmental impact of

Conduit Dynamics in Transitional Rhyolitic Activity Recorded by Tuffisite Vein Textures from the 2008–2009 Chaitén Eruption [PDF]

, 2016
The mechanisms of hazardous silicic eruptions are controlled by complex, poorly-understood conduit processes. Observations of recent Chilean rhyolite eruptions have revealed the importance of hybrid activity, involving simultaneous explosive and effusive
