Determining the current size and state of eruptible magma reservoirs
A team of volcanologists from the University of Geneva, in collaboration with the University of Heidelberg, has devised a technique that can predict the devastating potential of volcanoes thanks to zircon crystals contained in volcanic rocks.

The Paraná large igneous province did not trigger Valanginian climatic change
High-precision zircon U-Pb agee determinations from two magmatic units of the Paraná volcanic province in Brazil are 1.5 million years younger than the global positive carbon isotope excursion and the inferred global Valanginian climate crisis.

Volcanic ash as a secondary volcanic hazard
Volcanic ash can be remobilised and suspended in the atmosphere generating an important secondary volcanic hazard. The study reveals how volcanic particles are remobilised from primary deposits and how they deplete over time, with consequences to the environment and on the exposed communities.
