SEM3D-High-resolution seismic wave propagation modelling from the fault to the structure for realistic earthquake scenarios. GENCI Allocation A0080410444

The main activities of the last months were intended to the wave-propagation code SEM3D [1],based on Spectral Element Method, for the analysis of the seismic response of the Cadarache nuclear site and of the European experimental site of Argostoli (to conclude the activities started with allocations A4-A7). Those activities lead to the publication of one scientific paper to the top notch Journal of Seismology [2], to the submission of two scientific papers in September 2020 (still waiting for the reviews...) [3, 4], to the completion of a PhD thesis [5]. [1] CEA and CentraleSupélec and IPGP and CNRS. SEM3D Ver 2017.04 Registered at French Agency for Protection of Programs (Dépôt APP), 2017.
