The explosivity of volcanoes is largely governed by the loss of magmatic water, as explosivity decreases with increased water loss. For my PhD I have gained fresh insight into how rhyolitic (silica-rich) magma deforms during ascent, and how this influences water loss. I achieved this aim by conducting micro- to macro-scale analysis of the textures and magmatic water content in Icelandic dykes (pathways that connect magma chambers with Earth's surface).
