The Cargèse 2023 school will be held from October 9 to 13, 2023 at the IESC in Corsica and will focus on subduction zones. A 2-day field trip in Alpine Corsica will precede the school. 

Subduction zones are convergent plate boundaries, where oceanic plates sink into the mantle. They host the largest earthquakes, but also slow slip and tremors. The dynamics of subduction zones, their ability to host episodic tremor and slip, their segmentation depend on several parameters, such as the age and structure of the incoming plate, the geotherm, the presence of fluids, or the thickness and geology of the overriding plate. The factors controlling the time of occurrence and size of the earthquakes, the nature of the link between the slow slip events and the seismic rupture, the role of fluids, the structure and geology of the subduction channel, the rheology of the mantle and its impact on the short-term dynamics of the subduction zones are active areas of research.

The objective of this school is to provide young Earth scientists (Masters, PhD candidates, post-docs) with an overview of the state of the art and current challenges in the study of active subduction. We aim at gathering specialists of different fields, including geodynamic modelers, geologists, seismologists, geodesists, geophysicists to build bridges between these different disciplines and come up with a broad overview of the processes at stake in subduction zones. We also aim at discussing their potential interaction-retroaction effects.

This thematic school is organized in coordination with the FrenSZ network, that gathers the French researchers working on subduction zones. The thematic school will also benefit from the link with the projects of the different members of its scientific committee: The ERC DEEP-trigger (PI A Socquet), the millenio CYCLO project (PI D Melnick), the Science of slow to fast earthquake project (PI S Ide), an extension of the Science of Slow earthquakes project, and the subduction zone 4D initiative.
