Melting Glaciers Could Trigger More Explosive Volcanic Eruptions Globally
(www.eurekalert.org)
By precisely dating previous eruptions and analysing crystals in erupted rocks, the team tracked how the weight and pressure of glacial ice alter the characteristics of magma underground.
They found that during the peak of the last ice age (around 26,000โ18,000 years ago), thick ice cover suppressed the volume of eruptions and allowed a large reservoir of silica-rich magma to accumulate 10-15 km below the surface.
