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 …

Field, geochronological and geophysical studies show that many igneous bodies are
emplaced incrementally, growing by accretion of successive magma sheets. The existence …

Granitoids are a major component of the continental crust. They play a pivotal role in its
evolution, either by adding new material (continental growth), or by reworking older …

The structure of upper crustal magma plumbing systems controls the distribution of
volcanism and influences tectonic processes. However, delineating the structure and …

Over the last few decades, significant advances in using geophysical techniques to image
the structure of magma plumbing systems have enabled the identification of zones of melt …

Abstract Olivier Bachmann is Professor of volcanology and magmatic petrology at the ETH
Zürich. He obtained his PhD at the University of Geneva, and held positions of post-doctoral …

Large-scale, explosive volcanic eruptions are one of the Earth's most hazardous natural
phenomena. We demonstrate that their size, frequency, and composition can be explained …

Storage pressures of magma chambers influence the style, frequency and magnitude of
volcanic eruptions. Neutral buoyancy or rheological transitions are commonly assumed to …

The formation of world class porphyry copper deposits reflect magmatic processes that take
place in a deeper and much larger underlying magmatic system, which provides the source …

The modification of magma through mixing or through assimilation of country rocks is
commonly inferred from various chemical and isotopic features of magmatic rock suites and …
