  1. Preface

    The predictability of earthquakes has been debated since many decades, particularly their long-term recurrence (when, where and which magnitude). The nonlinearlity of the governing physics behind the process, the complexity of the Earth's interior and the uncertainty of the observable parameters are all factors which make earthquake prediction almost impossible …

  2. Project objective

    Our strategy is thus to map seismic activity in space and time as precisely as possible, involving various scale phenomena (the purpose of WP1 & WP2), construct the heterogeneous fault model (WP3) and study the sensibility and predictability (periodical behaviors and randomness) (WP4 & WP5). The episodic or periodic behaviors of tiny …
