Il est maintenant communément admis que les perturbations de fluide dans la croute terrestre génèrent des tremblements de terre. Par exemple, des essaims sismiques accompagnent les montées de magmas ou les activités anthropiques d'exploitations de réservoirs. La compréhension du lien entre les fluides et les séismes reste imparfaite, même si...

Fluid induced earthquake sequences generally appear as expanding swarms activating a particular fault. The recent analysis of a swarm in the Corinth rift has revealed a dual migration pattern, with a global slow expansion (m/day) and episodes of rapid migration (km/day). Such swarms are generally interpreted as fluid diffusion, which ignores...

The primary processes driving seismic swarms are still under debate. Here, we study the temporal evolution of a seismic swarm that occurred over a 10-day period in October 2015 in the extensional rift of the Corinth Gulf (Greece) using high-resolution earthquakes relocations. The seismicity radially migrates on a normal fault at a fluid...

Wave propagation in heterogenous two dimension porous media plays an important role for subsurface investigation. We consider solving dynamic wave propagation using discontinuous Galerkin method in frequency domain. This spectral approach allows us to efficiently take into account diffusive phenomena related to Biot theory on porous medium at...
