Mobility of Magmas Within the Earth: Insights From the Elasticity and Transport Properties of Hydrous Albitic Melts

Geochemistry, Geophysics, Geosystems
The continental crust is produced by the solidification of aluminosilicate‐rich magmas which are sourced from deep below the surface. Migration of the magma depends on the density (ρ) contrast to source rocks and the melt viscosity (η).

Vegetation responses to past volcanic disturbances at the Araucaria araucana forest-steppe ecotone in northern Patagonia. [PDF]

Ecol Evol, 2022
Although past volcanic eruption might have affected the distribution of Araucaria' populations, thus its conservation status, I found no evidences that past tephra fall has impacted negatively the populations far from the volcanic source. Early succecional stages after severe tephra fall deposition were better explained by Ephedra' drought tolerance ...

Assessing woody vegetation recovery in the Rayas River following the eruption of the Chaitén Volcano in 2008

Geological Society Special Publication, 2021
We studied the recovery of the woody vegetation in a segment of the Rayas River, that drains the Chaitén Volcano, in southern Chile. Data collection in the river corridor was performed to assess the regeneration rates of the colonizing vegetation within ...

Volcano monitoring and hazard assessments in Chile

Volcanica, 2021
Volcanism in Chile occurs in a variety of tectonic settings but mostly in the context of oceanic-continental plate collision, including 92 potentially active volcanoes. There have been more than 30 documented eruptions in the last few centuries.

Post-fragmentation vesiculation timescales in hydrous rhyolitic bombs from Chaitén volcano

Journal of South American Earth Sciences, 2020
Bubble nucleation and growth dynamics exert a primary control on the explosivity of volcanic eruptions. Numerous theoretical and experimental studies aim to capture the complex process of melt vesiculation, whereas textural studies use vesicle ...

Stratigraphy of volcanic memory: Sociocultural dimensions of volcanic risk in the Southern Andes, Chile

Journal of Contingencies and Crisis Management, Volume 31, Issue 4, Page 1018-1033, December 2023., 2023
Abstract This article focuses on communities that reoccupy territories affected by volcanic eruptions to extend understanding of people's social appropriation of environments exposed to natural hazards. We take as a case study three rural settlements affected by several eruptions from the Carran‐Los Venados and Puyehue‐Cordón Caulle volcanic systems ...

Spatial and Temporal Resolution Needs for Volcano Topographic Change Data Sets Based on Past Eruptions (1980–2019)

Earth and Space Science, Volume 10, Issue 10, October 2023., 2023
Abstract Up‐to‐date topography data sets are essential for forecasting volcanic hazards and monitoring deformation. Digital elevation models are used to quantify eruption rates, used in flow modeling programs, and are necessary to accurately process interferometric synthetic aperture radar data for surface deformation.
