« Analyzing and modeling foreshock sequences »
Foreshocks often precede large earthquakes, and have therefore been intensively studied as possible precursory phenomena. However, they do not systematically occur, and their relationship with the incoming mainshock is not clear. Opposite views have emerged, that
see foreshocks as either the cause of the mainshock, or as a by-product. In the latter model, the mainshock and the foreshocks all result from a common process, that some authors suggest to be pre-slip on the main fault. To discriminate between these two
models, it is important to quantify how much the foreshocks could contribute to the development of the sequence and to the loading of the main asperity.
The goal of this post-doc will be to further develop and test methods that account for both earthquake interactions and aseismic loading in the occurrence of foreshocks and the mainshock.
This work takes place within the framework of the FP7 European project REAKT. The scientist will be based at ISTerre (isterre.fr), either in Grenoble or in Chambéry, according to his/her wish. This work will be done in collaboration with David Marsan, Michel Bouchon and Agnès Helmstetter (all at ISTerre).
A PhD in Earth Sciences is required for this position. The candidate will have a strong background in earthquake physics. Some knowledge on probabilistic modelling will be appreciated.
This position is to open in spring 2012, and to end on the 31/03/2014. The salary is 2055 € per month (CNRS post-doc salary).
Further details can be obtained by e-mailing to David Marsan (firstname.lastname@example.org). To apply, candidates must provide a detailed CV at this address.
