The 2008 Movri earthquake

The 2008 mainshock (Mw 6.4) was the first modern, strong strike-slip earthquake in the Greek mainland. Using satellite interferometry techniques we detected maximum deformation in Kato Achaia and correlated it with an elastic dislocation model. Apart from Kato Achaia, no additional co-seismic movement was identified. Information on the observed uplift pattern, in conjunction with the aftershock seismicity sequence, and in-situ observations led to the conclusion that the causal association between ground displacement and increased earthquake damage in the hanging wall of the motion becomes possible not only for pure dip-slip earthquakes but also for strike-slip earthquakes with small dip-slip component.
