The build-up and triggers of volcanic eruptions
More than 800 million people live in proximity to active volcanoes and could be directly
impacted by potential eruptions. Mitigation of future volcanic hazards requires adequate …

Numerical modelling of dykes deflected into sills to form a magma chamber
ZA Barnett, A Gudmundsson - Journal of Volcanology and Geothermal …, 2014 - Elsevier
Most shallow magma chambers are thought to evolve from sills. For this to happen, several
conditions must be met.(1) There must be a discontinuity, normally a contact, that deflects a …
