Neotectonic structure and evolution of Lefkada island

2001

In this paper, the formations that participate in the geological structure of Lefkada island are described in detail, as well as two alpine tectonic phases that affected the island, together with the criteria for their evaluation. The tectonic fabric is then described and the mapped fault systems are analysed kinematically and geometrically through the time. The current geodynamic regime has found its expression on the island through a dense fault network that has overprinted the pre-existing thrust-related features and has been dominant throughout the Plioquaternary. The dense fault network has broken up the island in a multitude of independent fault blocks which are described; an attempt is also made to determine the relative movements among these fault-blocks. The recent geological history of Lefkada is characterized by basic periods of predominant compression, interrupted by brief extensional episodes, where gravitational movements are favoured.

“…The Pre-Apulian or Paxos zone corresponds to mixed neritic/pelagic sedimentation, reaching into the Aquitanian, overlain by Miocene marl sequence. This zone was previously regarded as the undeformed Hellenides foreland but more recent work revealed that it was dominated by shortening during Tertiary-Quaternary times (Underhill, 1989).…”

“…They constitute part of the para-autochthonous Apulian foreland of the Hellenide orogen and include rocks of the Pre-Apulian (or Paxos) and Ionian isopic zones (Aubouin, 1957;1965;Underhill, 1989). The Pre-Apulian or Paxos zone corresponds to mixed neritic/pelagic sedimentation, reaching into the Aquitanian, overlain by Miocene marl sequence.…”

“…Studies of the focal mechanisms from earthquakes within the area, have shown that the tectonic regime of the area varies from thrust and strike slip to normal (Mercier et al, 1972;King et al, 1983;Doutsos et al, 1987;Underhill, 1989;Waters, 1994;Hatzfeld et al, 1995).…”

Earthquake relocation for North-Western Greece using 3D crustal model; method comparison and seismotectonic interpretation.

A dense microseismic network was installed in Northwestern Greece for a period of eleven months. A total of 1368 events were recorded and located using a 1D model. These events were also used to derive a 3D velocity model for the area. This work presents results from further processing of the data using (a) simple location method of events in a 1D medium through Hypo71 standard procedure; (b) location via the probabilistic, non-linear earthquake location method in 3D medium; (c) relocation of the events using the Double - Difference method in 1D medium; and (d) the same relocation procedure invoking 3D medium. The application of different location methodologies results in slightly different locations, which are evaluated using as criterion the compactness of hypocenter distribution. The three point method was used in order to derive linear characteristics from the hypocenter distribution and the final results were compared against the focal mechanisms of the events as computed using the polarity method and the 3D velocity model. The combination of accurately computed hypocenters and focal mechanisms provides important information for the seismotectonics of Epirus
