Flagship Research Projects

The REMAKE project, funded by the French National Research Agency, aims at developing a pilot prototype of earthquake forecast model in Ecuador and Northern Peru, a region frequently affected by devastating earthquakes, such as the Pedernales earthquake of 16 April 2016. The novelty of the model is that it will integrate all existing and forthcoming knowledge on faults, including their seismic potential quantitatively assessed from geodetic, seismological, and geological approaches. The primary deliverable will address the issues of anticipation of potential future extreme events, in terms of location, size, and frequency, which will be translated into the probability of exceeding the specified ground-motion level.

SISMED lowThe southwestern segment of the Hellenic subduction zone has generated a M>8 tsunamigenic earthquake in the past (365 AD), the largest event ever reported in Europe, but fundamental questions remain about the deep geometry and characteristics of the interplate fault and connected splay faults in the overriding plate that might be rooted in the megathrust. In the Fall 2015, we chartered the R/V Marcus Langseth equipped with unmatched seismic facilities in the European academic fleet by means of a strong mobilization of the French and American involved laboratories (Géoazur, LDEO, ISTEP, ENS-Paris, EOST, LDO, Pau Univ.) and their research agencies (CNRS, NSF, OCA, and UCA).

SEISMES Vignette EPOSTThe Early POSTseismic Deformation: a Key Process in the Earthquake Cycle. From Observation to Modeling.

The main objective of the project is to better understand the complex space and time evolution of postseismic transient processes to better assess their link with the coseismic processes and how they contribute to the stress redistribution, which might lead to the generation of catastrophic seismic sequences. The originality of the project is to focus on the shorter time scale of the postseismic phase, the transition from the co- to postseismic (i.e. early postseismic, from minutes to early days) and to test to what extent the better description and knowledge of the co- and early postseismic deformation help to resolve the longer time-scale postseismic deformation (months - years).

The E-POST Young Researcher project is supported by the main French Research Funding Agency ANR over the period 2015-2019.
