Résumé:	Le risque sismique résulte de l'aléa sismique et de la vulnérabilité des ouvrages. La connaissance de l'aléa repose sur la géologie et la sismicité (historique et instrumentale) de la région, mais les mouvements sismiques peuvent aussi présenter une grande sensibilité aux conditions de site. La vulnérabilité peut être liée au sol de fondation (phénomène de liquéfaction), à une mauvaise conception et surtout à une mauvaise qualité de réalisation. Les progrès de l'ingénierie permettent de bien maîtriser des ouvrages neufs.
