Rhyolite eruptions under ice:an interconnected web of volatiles, pressure, degassing, and eruptive behaviour
Subglacial rhyolite volcanoes demonstrate an intricate, complex, and poorly-understood connectivity between volatiles, pressure, degassing, and eruptive behaviour. We examine these relationships at different subglacial rhyolitic volcanoes at Torfajökull, South Iceland. Evidence suggests that the eru...
