“…The focal mechanisms vary from strike slip and normal for most of the earthquakes, which changes to thrust along NW-SE direction for some earthquakes. This observation agrees with the previous studies in the area performed by IGSR and IFP, (1966); King et al, (1993); Hatzfeld et al, (1995) and Tselentis et al, (2006) who mapped normal and oblique-normal focal mechanisms which became pure strike-slip and even the reverse for some earthquakes. According to them, the variety of faulting type implies the existence of two groups of faults, a group of oblique to normal faults that trend N-NW-SE and a group of almost vertical reverse faults of N-S trend.…”

“…Geomorphological work performed by King et al, (1983) using boundary-element modelling, identified a substantial left lateral strike-slip component in addition to the compressional motion. Furthermore, geological and geomorphological research which was conducted by IGSR and IFP, (1966) and King et al, (1993) as well as crustal deformation studying of the Aegean area by Papazachos and Kiratzi, (1996), implied similar results.…”

“…Cluster 9 is a small cluster of 15 events extended from 24 to 35km depth at the Doliana basin (King et al, 1993), (Figure 2). The fault plane solutions derived for these events show thrust and oblique thrust faulting with a mean strike at NW-SE direction.…”

“…The majority of earthquakes occur at shallow depths up to 5km with just a few deeper events limited at 10km. This area between Mitsikeli (M) and Kourenton (K) thrust (Figure 2) was referred by King et al, (1993) as Ioannina basin. Tselentis et al, (2006), found normal focal mechanisms in this area and related them with a set of conjugate normal faults, structures that can develop on top of evaporite domes.…”

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

“…King et al (1983), based on a boundary-element model proposed a substantial left lateral strike-slip component in addition to the compressional motion. In agreement with this idea are the results of the geological and geomorphological research performed by IGSR and IFP (1966) and King et al (1993) and the crustal deformation study of the Aegean area performed by Papazachos and Kiratzi (1996). At the Epirus area the extensional inner Aegean regime switches to the compressional outer Aegean.…”

Strain and rotation rate patterns of mainland Greece from continuous GPS data and comparison between seismic and geodetic moment release

We processed data from~100 continuous GPS stations to provide new insights into the crustal motion and deformation of central and western Greece. We used the derived velocity field to evaluate two-dimensional strain and rotation rate tensors, and we mapped the dilatation and maximum shear strain rates. In central Peloponnese and Epirus, we documented a 90°switch in the extension direction, which can be explained on the basis of the plate boundary configuration. Evidence for an extended deformation pattern in central Greece was found. Additionally, we detected two pairs of shear belts, one in Akarnania-NW Peloponnese and one in North Aegean. We delineated two rotational domains that dominate the present-day pattern. Moreover, we saw no geodetic evidence for North Anatolian Fault growth toward central Greece. We translated the geodetic strain rates into rates of seismic moment release and compared them with earthquake catalog-based moment rates. In the central Ionian Sea, the geodetic strain is completely released seismically, which is indicative of a fully coupled seismogenic zone. However, for most of the study area, the geodesy-based moment rates are at least 2 times higher than the earthquake-based rates. We attribute this mainly to earthquake catalog representativity over the long-term situation. However, for the Gulf of Corinth, it is unrealistic to associate the high ratio of geodetic to seismic moment rates only to incompleteness of the earthquake catalog; instead, long-term aseismic deformation must be an important mechanism accommodating a considerable portion of the strain budget, especially at its western part.
