Structural characteristics of two strong earthquakes in the North Aegean :
Publication:
, Structural analysis has been carried out on the volcanics of the island of Agios Efstratios and along the highly faulted zone of SE Chalkidiki, south and north of the North Aegean Trough, respectively (northern Greece). The areas have been affected by strong earthquakes and a comparison is made between the available structural and seismological data, together with new seismotectonic information. At Agios Efstratios, the earthquake of 1968 (M7.1)occurred on a principal displacement zone with dextral strike-slip movement, while the fault geometry of the whole area supports the view of transtensional deformation. The strong (M7.0)earthquake of 1932 at Ierissos was directly connected with an E-W-trending normal fault. Striations on the seismic fault surfaces and the corresponding fault mechanism indicate a N-S direction of active extension. The hangingwall is also affected by smaller antithetic E-W-and NW-SE-trending structures (AU).
