Volcanic ash forecast – application to the May 2008 Chaitén eruption [PDF]
Natural Hazards and Earth System Sciences, 2008 We model the transport and subsequent deposition of ash from Chaitén volcano, Chile, during the first week of May 2008. The simulation couples the Weather Research and Forecasting (WRF) meteorological model with the FALL3D dispersion model.

Major fluvial erosion and a 500‐Mt sediment pulse triggered by lava‐dam failure, Río Coca, Ecuador
Earth Surface Processes and Landforms, Volume 49, Issue 3, Page 1058-1080, 15 March 2024.The failure of a 144‐m‐high lava dam on the Río Coca, Ecuador, in 2020 initiated major regressive erosion as the river evolved towards a new equilibrium grade. Erosion generated a 277 million m3, ~500 Mt sediment pulse over three years, one of the largest in modern times.

Characterizing Volcanic Ash Density and Its Implications on Settling Dynamics
Journal of Geophysical Research: Atmospheres, Volume 129, Issue 2, 28 January 2024.Abstract Volcanic ash clouds are carefully monitored as they present a significant hazard to humans and aircraft. The primary tool for forecasting the transport of ash from a volcano is dispersion modeling. These models make a number of assumptions about the size, sphericity and density of the ash particles. Few studies have measured the density of ash

Tephra stratigraphy and eruptive volume of the May, 2008, Chaitén eruption, Chile [PDF]
, 2018 On May 1st 2008 Mount Chaitén (southern Chile) interrupted a long period of quiescence, generating a sequence of explosive eruptions and causing the evacuation of Chaitén town located a few kilometers south of the volcano.
