Volcano Geodesy: Recent developments and future challenges
Ascent of magma through Earth's crust is normally associated with, among other effects,
ground deformation and gravity changes. Geodesy is thus a valuable tool for monitoring and …

Unexpected large eruptions from buoyant magma bodies within viscoelastic crust
Large volume effusive eruptions with relatively minor observed precursory signals are at
odds with widely used models to interpret volcano deformation. Here we propose a new …
