THE ATHENS EARTHQUAKE SEPTEMBER 7, 1999 NEOTECTONIC REGIME AND GEODYNAMIC PHENOMENA

摘要

At September 7th 1999, an earthquake with a magnitude of M_w=5.9 struck mainly the western suburbs of Athens (Greece). In this paper, an attempt for the description of the morphotectonic evolution of the area affected by the earthquake is made. This attempt is based on observations concerning the general morphotectonic structure of Attica and on data concerning the geological - alpine and post-alpine - formations and structure. It is shown that the regional stress field has to be more complicated than a pure extensional regime, so that the geometry and kinematics of the area are interpreted sufficiently.
