Palaeoseismological investigation across the Gyrtoni Fault, Tyrnavos Basin, Central Greece

We present the preliminary results of a palaeoseismological investigation carried out along the Gyrtoni Fault, Tyrnavos Basin (Central Greece), of which the occurrence and recent tectonic activity was previously based only on non invasive techniques, like mapping, remote sensing analyses and electrical resistivity tomographies. Two palaeoseismological trenches emphasize the occurrence of 2 palaeoearthquake displacements in the past ~4.0 ka. An ongoing dating of the collected samples, using the Optically Stimulated Luminescence (OSL) and 14C methodologies, is expected to permit us to constrain the timing of the linear morphogenic earthquakes observed in the trenches and thus reconstruct the recent seismotectonic behaviour of the fault
