Offer Description

A world-renowned geosciences organisation, the IPGP is associated with the CNRS and an integrated institute of the Université Paris Cité. 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 research areas are structured through 4 main unifying themes: Interiors of the Earth and Planets, Natural Hazards, Earth System and Origins.

The IPGP is in charge of labelled observation services in volcanology, seismology, magnetism, gravimetry and erosion. The IPGP's permanent observatories monitor the four active French overseas volcanoes in Guadeloupe, Martinique, Réunion Island and Mayotte.

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 combines observation, quantitative analysis and modelling, reflecting the quality, richness and thematic diversity of the research conducted by the IPGP teams.

Team Department

The IPGP Seismology team covers the full breadth of the discipline—studying seismic sources such as earthquakes, slow and transient deformation, volcanic activity, landslides, glaciers, and oceanic movements, as well as the structures these waves traverse, from the near-surface to the Earth's deepest layers. Our research integrates the development of cutting-edge instruments, in situ sensor deployment, data analysis, and advanced numerical modeling.

Missions

Distributed Acoustic Sensing (DAS) is a rapidly evolving technology that turns standard fiber-optic cables into dense seismic sensor arrays. By detecting tiny changes in backscattered light, DAS captures ground vibrations with high spatial and temporal resolution over tens of kilometers and thousands of sensing points. This technology is being deployed at European Near Fault Observatories (NFOs)—such as the Irpinia Fault (Italy) and the Corinth Rift (Greece)—to build detailed seismic catalogs, image fault structures, and improve understanding of earthquake nucleation and interaction.

A major challenge of DAS is the enormous data volume it generates, with typical deployments producing around one terabyte per day. To address this, we will develop machine learning methods that treat DAS data as images and leverage computer vision techniques to detect seismic events. This will enable fast identification of relevant time windows, allowing selective data retention and significantly reducing storage needs.

This work is part of the EU-funded TRANSFORM² project, which aims at strengthening Europe’s NFOs through the integration of advanced sensing, fiber-optic monitoring, and machine learning to improve fault monitoring, earthquake detection, and early warning systems.

Activities

The appointed researcher will take a leading role in developing computer vision algorithms to detect seismic events within DAS record sections, treated as images. This work will build on existing tools for processing DAS data, which will be used to generate the record section images. The primary focus will be on constructing a high-quality training dataset and designing machine learning models tailored to the unique characteristics of DAS images.

Obligations and Risks

Work schedule
Full-time position, with a weekly workload ranging from 35h20 to 38h50, in accordance with institutional regulations.

Work attendance
The researcher is expected to participate in at least two team meetings per week at the laboratory. Remote work is possible one to two days per week, depending on project needs and team coordination.

Professional travel
The position may include occasional travel, particularly to attend meetings and workshops related to the TRANSFORM² project.
