Last update

[24th of July]: The number of pre-registered and registered participants has reached the maximum capacity, and we thus cannot accept any more participants.

[19th of August]: A transfert by bus from Ajaccio Airport will be organized on the 2nd of November after the flight from Paris Orly arriving at 15:55 has landed. Another bus will also depart later that day, depending on the arrivals of the participants. Transfert from Cargèse to Ajaccio Airport on the 11th will be organized when the departure times of all participants are known.

[2nd of October]: The program is available.

 

School Outline

Earthquakes remain unpredictable, despite decades of intense investigations on possible precursory phenomena. Key challenges include our inability to monitor the state of stress on active faults at seismogenic depths, and to fully understand how rupture initiates and stops in a complex medium characterized by a highly variable stress field.

In the last 10 years or so, great advances have converged towards a much more complete picture of earthquake-related processes. The quality, quantity and distribution of seismic, geodeteic and geologic data have improved significantly, particularly owing to the development of very dense monitoring networks. These advances have led to greatly enhanced resolution and have revealed the ubiquitous nature of aseismic slip. Additionally, the occurrences of several mega-thrust and continental earthquakes have fed the scientific community with very rich datasets.

The goal of this school is to give PhD students, post-docs and young scientists an accurate snapshot of our current understanding of how earthquakes nucleate and can be triggered, in the light of recent improvements. About 20 scientists from all around the world (mostly Europe, US, Japan), at the cutting-edge of earthquake research, will give lectures together with ‘hands-on’ classes focusing on methods and softwares. A large spectrum of topics will be covered, from the analysis and modeling of regional-scale geodetic data, to the very detailed investigation of repeating earthquakes at the 100 meter asperity scale. Thus, as complete a description of earthquake-related phenomena as possible will be discussed. Since consensus has not yet been reached in many aspects of this domain, most topics will be covered by different lectures with contrasting views. The school is intended to stimulate the emergence of a much wider understanding of the current issues and new ideas, particularly among young scientists (PhDs and post-docs), and will thus facilitate future collective momentum towards earthquake preparedness and forecasting.
