<div><strong>PhD thesis on Numerical Modelling and Petrological Analyses of Phreatic Eruptions</strong></div>
<div><strong>of Copahue Volcano (Argentina / Chile)</strong></div>
<div><br>
<strong>Context</strong></div>
<div><br>
Phreatic eruptions do not necessarily involve the ascent of new magma to the surface, and often</div>
<div>occur with minimal monitoring of unrest signals or warnings. Nevertheless, they can eject rocks</div>
<div>and ash into the air and, in some cases, trigger pyroclastic density flows. Volcanoes with large</div>
<div>hydrothermal systems commonly experience phreatic and phreato-magmatic eruptions before</div>
<div>larger magmatic eruptions. Despite growing awareness of the high risk associated with phreatic</div>
<div>eruptions, many aspects of the processes leading to such events remain poorly understood. This</div>
<div>PhD project is part of an ANR-funded initiative aimed at understanding the mechanisms driving</div>
<div>phreatic and phreatomagmatic eruptions at Copahue Volcano (Patagonia). Copahue has been one</div>
<div>of the most active volcanoes of the region in the past 30 years, and is considered by the Argentine</div>
<div>Observatory of Volcanic Surveillance (<span style="color:#0000ff;"><u>https://oavv.segemar.gob.ar/monitoreo-volcanico/copahue/</u></span>) to pose the highest risk out of 39</div>
<div>active volcanos in the country.</div>
<div><br>
<strong>PhD project</strong></div>
<div><br>
The successful PhD candidate will study ash deposits from recent eruptions to quantify the relative</div>
<div>contributions of magmatic and hydrothermal sources, and analyse their temporal evolution. He/she</div>
<div>will perform numerical simulations of fluid and heat flow in the hydrothermal system to determine</div>
<div>whether the recurrent eruptions at Copahue Volcano can be driven by sealing of the hydrothermal</div>
<div>system, seasonal variations of precipitation and lake size, and/or magmatic fluid flux variations.</div>
<div>The position is scheduled to start in October 2025. It is fully funded for 3 years. The project</div>
<div>includes fieldwork at Copahue Volcano, and active collaborations and a research stay in OAVV.</div>
<div><br>
<strong>The Institut de Physique du Globe de Paris</strong></div>
<div> </div>
<div>The position is based in the Institut de Physique du Globe de Paris (<span style="color:#0000ff;"><u>https://www.ipgp.fr/</u></span>, Paris, France), a world-</div>
<div>renowned geosciences organisation. Bringing together more than 500 people, the IPGP studies</div>
<div>the Earth and the planets from the core to the most superficial fluid envelopes, through observation,</div>
<div>experimentation and modelling. The IPGP hosts powerful computing resources and state-of-the-art</div>
<div>experimental and analytical facilities and benefits from first-class technical support. The IPGP</div>
<div>provides its students with geosciences training that combine observation, quantitative analysis and</div>
<div>modelling, and that reflects the quality, richness and thematic diversity of the research conducted</div>
<div>by the IPGP teams.</div>
</div>
<p><br>
<br>
<strong>Required skills</strong><br></p>
<div>We are looking for candidates with previous experience, or strong motivation in, numerical</div>
<div>simulations, petrological analyses, fieldwork, and integrating numerical and laboratory results. The</div>
<div>candidate will also have interest to interact with the OAVV and the multi-disciplinary team of the</div>
<div>ANR project.<br>
</div>
<div><strong>How to apply</strong></div>
<div> </div>
<div>To apply please send a CV, cover letter, and contact details of two references to Marina Rosas-</div>
