3D MONITORING OF ONSHORE ACTIVE FAULTS IN THE REGION OF THE GULF OF CORINTH (GREECE)

Abstract

The Gulf of Corinth is the most active extensional feature in Europe with extension rates of 7-16 mm/year in N-S direction (ARMIJO et alii, 1996, DAVIES et alii, 1997). This extensional activ­ity is accommodated on both offshore and onshore WNW-ESE trending faults. Our project concerns with the 3D monitoring of onshore fault displacements at a sub-millimetre scale. The aim is to quantify tectonic activity of fault scarps in this region by correlat­ing fault displacements with seismic activity. This will also lead to conclusions concerning the nature of the fault displacements ( seis­mic or aseismic creeping movements) as well as the potential re]a­tion between tectonic activity and slope instability phenomena which are observed in many areas.
