Crystal and melt inclusion timescales reveal the evolution of magma migration before eruption

Abstract

Volatile contents in melt inclusions can be used to unravel magma migration and degassing. Here, the authors use olivine chronometry and melt inclusion data from the 2008 Llaima eruption and find that magma intrusion occurred 4 years before the eruption and reached a depth of 3–4 km, 6 months before the eruption.
