Crustal deformation associated with east Mediterranean strike–slip earthquakes: The 8 June 2008 Movri (NW Peloponnese), Greece, earthquake (Mw6.4)

Hazard due to earthquake-induced rock falls: The use of remote sensing data and field mapping in the case of Skolis Mountain, NW Peloponnese

“…The historical and instrumental seismicity and geotectonic evolution of the NW Peloponnese and the Ionian Islands are in general well-known and widely reported (e.g. Hatzfeld et al, 1995;Sachpazi et al, 2000;Gallovic et al, 2009;Ganas et al, 2009;Papadopoulos et al, 2010;Royden and Papanikolaou, 2011;Vassilakis et al, 2011).…”

“…The earthquake caused the death of two people, injuries, extensive damage to the surrounding area (along a 30-km-long by 20-km-wide area) and was reported to have been felt as far away as 350 km from the epicentral area. The main shock that occurred at 12:25:28 (GMT) on 8 June 2008, was located at latitude 37.98 °N and longitude 21.51 °E and was followed by a series of aftershocks with a maximum magnitude aftershock of 5.1 (Ganas et al, 2009;Papadopoulos et al, 2010). Focal mechanisms of the main shock as well as the lateral and vertical distributions of the aftershocks imply a N35°E-striking blind dextral strike-slip fault (Ganas et al, 2009;Gallovic et al, 2009;Papadopoulos et al, 2010;Feng et al, 2010;Giannopoulos et al, 2013).…”

“…The earthquake toppled primarily old buildings and less reinforced houses and reinforced concrete buildings in the villages nearby its epicenter. The secondary effects that were caused by the Mw=6.4 earthquake, were landslides, rock falls and rock slides, liquefaction phenomena and ground ruptures, near the epicentral area providing a quite good case history to evaluate the role of the earthquakes on triggering landslides (Kokkalas et al, 2008;Pavlides et al, 2008;Koukouvelas et al, 2010;Papadopoulos et al, 2010). Seismic intensity assignments for this earthquakes based on the application of the Environmental Seismic Intensity scale (ESI 2007) and the European Macroseismic scale (EMS-98) suggest that a NE-SW trending elliptical area, including the Skolis Mountain, suffered by the event (see also Mavroulis et al, 2010).…”

The Crustal Anisotropy Pattern in the Epicentral Area of the 2008 Mw 6.4 Earthquake in Northwest Peloponnese, Greece

“…The main shock was accurately located by Konstantinou et al (2009) at a hypocentral depth of 18 km, using a shrinking grid-search relocation algorithm. Several studies have been performed to study the aftershock distribution and the rupture process of this event (Ganas et al, 2009;Gallovič et al, 2009;Konstantinou et al, 2009;Papadopoulos et al, 2010;Feng et al, 2010). Various organizations have provided moment tensor solutions (Institute of Geodynamics of the National Observatory of Athens, Harvard University, United States Geological Survey, Aristotle University of Thessaloniki, National and Kapodistrian University of Athens), which have indicated a nearly vertical dextral strike-slip fault striking NE-SW.…”
