La modélisation de la propagation des ondes sismiques permet deux choses :

– Prédire l’impact d’un séisme en tout point de l’espace, en fonction de la nature du sous-sol (vitesse des ondes P et S, densité), de la topographie, et des caractéristiques du glissement sur la faille

– Mieux comprendre les caractéristiques du glissement en comparant les données de terrain avec les données simulées.

Pour ce faire, TLS Geothermics utilise le logiciel SW4 développé par le Lawrence Livermore National Laboratory .
