Impacto ambiental de la interacción agua-ceniza en la erupción del 2011 del volcán Grimsvötn (Islandia)

The Grímsvötn volcanic eruption, from 21 to 28 May, 2011, was the largest eruption of the Grímsvötn Volcanic System since 1873. The main geochemical features of the potential environmental impact of the volcanic ash-water interaction were determined using two different leaching methods as proxies (b...

The main geochemical features of the potential environmental impact of the volcanic ash-water interaction were determined using two different leaching methods as proxies (batch and vertical flow through column experiments). The main findings reveal that Na, K, Ca, Mg, Si, Cl, S and F show the largest geochemical fluxes caused by the interaction of water and ash.

It is noteworthy that the chemical release is maximal during the first few hours of contact between tephra and water due to the dissolution of soluble salts from the ash surface.
