Résumé

The massif of Pyrenees, who results from compressive movement between Iberic and Eurasian tectonic plates and who marks out the natural border between France and Spain, presents a moderate seismicity responsible of many destructive earthquakes over history, which maximum magnitude could probably reach 6.0-6.5. Thus Pyrenees constitute one of the Spanish and French areas where the seismic hazard is the most important, what have led to the progressive development of seismological forecasting networks around the massif. In this context, the SISPyr Interreg project has as principal objective to allow the pooling of Pyrenean seismological data and to improve the massif coverage by the networks favouring the progressive transition to real-time data transfer technologies. In order to make profit of advantages offer by real-time seismology, the SISPyr project also aims at to assess the feasibility of a Pyrenean earthquake early warning system (EEW) that could emit early warnings few seconds before destructive seismic waves in case of major regional earthquake.
