   PHD THESIS ON NUMERICAL MODELLING AND PETROLOGICAL ANALYSES OF PHREATIC
ERUPTIONS
   OF COPAHUE VOLCANO (ARGENTINA / CHILE)

CONTEXT

Phreatic eruptions do not necessarily involve the ascent of new magma to
the surface, and often
   occur with minimal monitoring of unrest signals or warnings.
Nevertheless, they can eject rocks
   and ash into the air and, in some cases, trigger pyroclastic density
flows. Volcanoes with large
   hydrothermal systems commonly experience phreatic and phreato-magmatic
eruptions before
   larger magmatic eruptions. Despite growing awareness of the high risk
associated with phreatic
   eruptions, many aspects of the processes leading to such events remain
poorly understood. This
   PhD project is part of an ANR-funded initiative aimed at understanding
the mechanisms driving
   phreatic and phreatomagmatic eruptions at Copahue Volcano (Patagonia).
Copahue has been one
   of the most active volcanoes of the region in the past 30 years, and is
considered by the Argentine
   Observatory of Volcanic Surveillance
(_https://oavv.segemar.gob.ar/monitoreo-volcanico/copahue/_) to pose the
highest risk out of 39
   active volcanos in the country.

PHD PROJECT

The successful PhD candidate will study ash deposits from recent eruptions
to quantify the relative
   contributions of magmatic and hydrothermal sources, and analyse their
temporal evolution. He/she
   will perform numerical simulations of fluid and heat flow in the
hydrothermal system to determine
   whether the recurrent eruptions at Copahue Volcano can be driven by
sealing of the hydrothermal
   system, seasonal variations of precipitation and lake size, and/or
magmatic fluid flux variations.
   The position is scheduled to start in October 2025. It is fully funded
for 3 years. The project
   includes fieldwork at Copahue Volcano, and active collaborations and a
research stay in OAVV.

THE INSTITUT DE PHYSIQUE DU GLOBE DE PARIS
    
   The position is based in the Institut de Physique du Globe de Paris
(_https://www.ipgp.fr/_, Paris, France), a world-
   renowned geosciences organisation. Bringing together more than 500
people, the IPGP studies
   the Earth and the planets from the core to the most superficial fluid
envelopes, through observation,
   experimentation and modelling. The IPGP hosts powerful computing
resources and state-of-the-art
   experimental and analytical facilities and benefits from first-class
technical support. The IPGP
   provides its students with geosciences training that combine observation,
quantitative analysis and
   modelling, and that reflects the quality, richness and thematic diversity
of the research conducted
   by the IPGP teams.

REQUIRED SKILLS
  We are looking for candidates with previous experience, or strong
motivation in, numerical
  simulations, petrological analyses, fieldwork, and integrating numerical
and laboratory results. The
  candidate will also have interest to interact with the OAVV and the
multi-disciplinary team of the
  ANR project.
