Summary

The 1981 seismic paroxysm of the Corinthian gulf was well inside the framework, of the geodynamic evolution of this graben with its successive enlargement. The serious damage, the surface rupture and the secondary effects defined a seismic area of an E-W general direction, which coincides with the main tectonic axes.

The contribution of the tectonics, lithology and particular ground foundation conditions in the distribution of the seismic intensities has been clearly shown, after recording the damage, on the geological-tectonic map of a wider area and in maps, at a scale of 1∶2000, of four villages destroyed.

Les caractéristiques géotechniques du séisme de 1981 à l'est du golfe de corinthe, Grèce

Résumé

En 1981, le paroxysme séismique du golfe de Corinthe s'inscrit dans le cadre de l'évolution géodynamique de ce graben avec son élargissement progressif. Les dégats graves, la surface de rupture et les effets, secondaires ont bien délimité la région touchée, de direction générale E-W, coïncidant avec les axes tectoniques principaux.

La contribution de la tectonique, de la lithologie et des particularités des conditions de fondation, à la répartition de l'intensité séismique a été bien montrée après avoir comparé les dégâts aux levés d'une carte géologique-tectonique, et d'une carte détaillée à une échelle de 1∶2000 pour quatre villages détruits.
