Hydrothermal alteration is considered to promote volcano instability, but there are few data and models to robustly assess this hypothesis. MYGALE is a multidisciplinary and collaborative project that will combine laboratory measurements, geophysical techniques, and modelling to assess the role of alteration on the stability of La Soufrière de Guadeloupe (Eastern Caribbean). Time-lapse field geophysical measurements will map the extent and evolution of alteration, experiments will provide physical property data for altered rocks and timescales of alteration, and large-scale 4D numerical modelling will assess the influence of alteration on volcano stability by combing the geophysical and upscaled laboratory data. Working closely with the volcano observatory in Guadeloupe, MYGALE aims at designing optimised monitoring networks to better mitigate volcanic hazards. The results of MYGALE will be applicable for hazardous volcanoes worldwide. Ph. D one Location: Strasbourg Institute of Earth & Environment (France) Main supervisor: Mike Heap (heap@xxxxxxxxxx) Topic: The influence of alteration on the mechanical behaviour of volcanic rocks Start date: from September 2022 to January 2023 Duration: 3 years Short description: This project will involve untangling the complex influence of hydrothermal alteration on rock physical and mechanical properties. The project will involve fieldwork at La Soufrière de Guadeloupe and performing a wide range of laboratory experiments, including uniaxial and triaxial deformation experiments.

D two Location: Institute of Earth Sciences at Orléans (France) Main supervisor: Caroline Martel (caroline.martel@xxxxxxxxxxxxxxx) Topic: Timescales for the hydrothermal alteration of volcanic rocks Start date: from September 2022 to January 2023 Duration: 3 years Short description: This project will involve understanding the timescales required for hydrothermal alteration. The project will involve fieldwork at La Soufrière de Guadeloupe and performing high-pressure, high-temperature alteration experiments in the laboratory. Changes resulting from alteration will be tracked using X-ray computed tomography, X-ray diffraction, and physical and mechanical property measurements.
