500 million people live in proximity of volcanoes and eruptions have a significant social and economical impact, thus forecasting the recurrence rate of volcanic eruption remains a great challenge in science. The target of FEVER is to produce a physically based statistical model able to ForEcast the recurrence rate of Volcanic ERuptions both at regional and global scale. What are the processes that control the size and frequency of volcanism at an individual, regional and global scale? Using a range of geochemical and statistical techniques FEVER tackles this question.
New paper in Frontiers in Earth Sciences - May 2020
We use graphical models called bayesian networks to investigate the probabilistic relationships between regional tectonic parameters and the sizes of large explosive events in the volcanic eruption record. This allows us to compare different volcanic arcs and explore the possible processes that control the accumulation and eruption of magma on Earth.
New paper in Frontiers in Earth Sciences - March 2020
We use a machine learning approach to identify the relationships between the chemical complexity of clinopyroxene crystals and the thermal evolution of the plumbing system for the 2014-2015 Holuhraun-Bardarbunga eruption.
Research published in Geophysical Research Letters - December 2019
In a multidisciplinary study involving the "Istituto Nazionale di Geopfisica e Vulcanologia" (INGV, Italy) and the University of Roma Tre, we show that the cause of the deadly earthquakes at Ischia, the last of which occurred in 2017, is linked to magma degassing. This study also show that the seismicity at Ischia will continue for centuries.
At this year’s Swiss Geoscience Meeting in Fribourg, our master student Corin Jorgenson was awarded the price for the best poster.
Research published in Journal of Geophysical Research: Solid Earth - October 2019
Using chemical analysis of mineral zoning profiles and diffusion modelling, we were able to track the sequence of magmatic events and timescales prior to Plinian eruptions from Nevado de Toluca volcano in Central Mexico. Such information is critical in order to evaluate the timing and nature of monitoring signals that could emerge before to an explosive eruption in this densely populated area.
Oliver Higgins won an early Career Researcher award for the best presentation and the VoiLA workshop in Trinidad - September 2019
Oliver Higgins won an Early Career Researcher Award from Nature Communications for giving the best talk at the Volatiles in the Lesser Antilles workshop (Trinidad) in September 2019. This was presenting his PhD study which focusses on the magmatic system on St Kitts, Lesser Antilles.
New paper in Contributions to Mineralogy and Petrology - March 2019
Geochemical and structural data from the Murato sill in Japan, combined with thermal modelling, enabled us to quantify extraction timescales and the range of crystallinity at which melt extraction occurred. These results improve the understanding of the dynamics of melt accumulation in magmatic bodies.
St Kitts fieldwork - January/February 2019
Ollie, Tom & Luca spent two weeks on the volcanic island of St Kitts in the Caribbean as part of Ollie's PhD project. They collected samples to analyse back in Geneva and characterised the stratigraphy of the volcanic deposits exposed along the Atlantic coastline.
New Paper in EPSL - January 2019
Understanding the role of H20 on the extraction of residual melts from crystalline magmas. In this study we address the effect of magma water content on the distribution and volume of crystal-poor and eruptible magma that can be extracted from crystallising magma reservoirs.
Southern Rocky Mountains Fieldwork - August 2018
Adam and Greg visited the USA for a second campaign in Adam's field area. They were there to collect more samples to help constrain the processes that led to a sequence of three ignimbrite-forming eruptions.
Research published in Earth and Planetary Science Letters - April 2018
Exploring the physical and chemical changes in magmatic systems resulting from flushing of CO2.
Volcanology outreach - March 2018
Introducing volcanology to the youthful readership of Frontiers for Young Minds: Does the shape of a volcano reflect it's personality?
New paper in Contributions to Mineralogy and Petrology - February 2018
How to quantify if crystals share similar histories or experience similar processes? This research presents a methodology to correlate profiles of chemical zonation within magmatic crystals.
Mexico fieldwork - January 2018
Greg, Adam and Luca visited Mexico to perform a second sampling campaign on Nevado de Toluca. Greg also presented his research at Instituto de Geología UNAM, Mexico City. You can see his presentation by clicking on the picture to the left.
New paper in Nature Geoscience - September 2017
New research indicates sea level changes associated with the Messinian Salinity Crisis lead to increased volcanism in the Mediterranean region.
IAVCEI - Portland - August 2017
We just came back from a successful volcanology conference where we gave 6 talks and 3 posters on various aspects of our research.
New paper in the Journal of Petrology - April 2017
The Takidani pluton shows evidences of extraction of residual melt from crystallising magma and textures produced by the pressure drop associated with volcanic eruptions.
