In this work, the results of earthquake relocation, stress inversion and seismic&amp;nbsp;traveltime tomography are presented, towards investigating the geodynamics of the study area. Inversion&amp;nbsp;of ~2300 focal mechanisms indicates obliquity by 30 ̊ between shearing and the maximum horizontal&amp;nbsp;stress along the major strike-slip faults, consistent with clockwise crustal rotation. Within the lower crust,&amp;nbsp;the stress field appears to be constrained by larger scale deformation. Seismic velocity anomalies have&amp;nbsp;been resolved by regional body-wave traveltime tomography, applying an iterative tomographic inversion&amp;nbsp;scheme using phase data from more than 5000 seismic events. Preliminary 3D tomographic models indicate the presence of gross structures related with the western Hellenic Trench, the Cephalonia Transform&amp;nbsp;Fault (CTF), the Aitoloakarnania shear zone, the Corinth Gulf and the Messinia graben. Dipping towards&amp;nbsp;the east and segmentation of CTF between Cephalonia and Lefkas is evidenced by the resolved anomalies&amp;nbsp;while a predominant NE-SW oriented low velocity zone observed in central Peloponnesus, related with&amp;nbsp;dextral strike-slip faulting, marks a 90° rotation of the extensional stress direction that is found to occur&amp;nbsp;at both sides.&lt;/p&gt;</style></abstract></record></records></xml>
