Summary
The study and mapping of the landslides triggered by the seismic shocks in May and in September 1976 were carried out using systematic photointerpretative observations completed by field studies. The landslides consist mainly of rockfalls which frequently took place as a result of the reactivation of phenomena which existed before the earthquake; the relationship between the landslides and the geotectonic and morphological conditions of the slopes is discussed.
Résumé
L'étude et la cartographie des éboulements provoqués par les secousses sismiques de mai et septembre 1976 dans le Frioul ont été effectuées à partir d'une photo-interprétation systématique s'intégrant aux relevés de terrain.
Les éboulements observés essentiellement des chutes de blocs, sont caractérisés surtout par la réactivation de phénomènes antérieurs aux séismes. Ils sont mis en relation avec les conditions géotectoniques et morphologiques des versants.
