The successful candidate will test the ability of existing deep neural network
picking techniques to detect and locate earthquakes during active swarm
episodes observed on volcanoes and on active faults. As a first application
case, we intend to analyze pre-eruptive volcano-tectonic swarms at Piton de la
Fournaise volcano to characterize the spatio-temporal properties of magma
migration in the volcanic edifice. Funding is guaranteed for 18 months
starting at the end of 2022 or early 2023.
The Piton de la Fournaise Volcano Observatory of the Institut de Physique du
Globe de Paris invites applications for a postdoctoral researcher in the
framework of the ERC PRESEISMIC project. The postdoctoral research will focus
on the use of machine learning techniques to improve detection and
localization of earthquakes during seismic swarms.
Seismicity is currently one of the best tools to monitor transient aseismic
processes such as slow slip on active faults or magma migration on volcanoes.
However, given the large number of earthquakes to be identified and the
increase in the number of available stations, automated approaches are
The postdoctoral research will be conducted at the Piton de la Fournaise
Volcano Observatory (OVPF) located on La Réunion Island. The observatory is
in charge of monitoring the Piton de la Fournaise volcano since 1979. Since
2020, the OVPF is also in charge of monitoring the seismo-volcanic activity of
Mayotte. The successful candidate will be integrated within a small but
multidisciplinary active team of researchers working on one of the most active
volcanoes on the planet (with more than 2 eruptions / year since 2014). The
Observatory is located on La Réunion island, a hotspot of cultural diversity
with nearly 1 million people.
A recent Ph.D. in Geophysics (defended less than two years ago) and
experience with the analysis of seismological data are required. Skills in
signal processing, machine learning and in python are highly desired.
