Notre Terre Observer, mesurer et modéliser notre Terre pour mieux la comprendre, la gérer et l'enseigner, résume la vision des sciences de la Terre à l'institut de physique du globe de Paris. Cette approche scientifique conçoit les géosciences dans leur globalité, depuis la surface du globe aux profondeurs de la Terre interne, et ce à toutes les échelles, en temps ou dans l'espace. L'aspect pluridisciplinaire des recherches est fortement développé à l'IPGP afin de répondre aux grandes questions posées par la l'étude de la dynamique de la Terre interne, de la structure et l'évolution des planètes, de la dynamique naturelle de l'environnement et l'impact des activités humaines, de la modélisation, la prédiction et la gestion des catastrophes naturelles, tremblements de terre et éruptions volcaniques. Ces thèmes transverses sont présentés dans les pages de cette rubrique, sous l'angle de la recherche, de l'enseignement et en direction du grand public.
