M6.0 earthquake Greece


This was a shallow thrust, a very destructive type, but only an M6.  Nevertheless, the PGV right on top must be high.


Quite nice, hope most of the seismic energy was directed away.


This was on the outer islands, which obviously is in compression, as opposed to the famous inner islands which is all under extension.  I haven't looked at the news yet, so fingers crossed it didn't do much.

Update:  Minor damage, an M7.2 in 1953, up the coast, was devastating.

Update2:  Now it is strike-slip along a little transform.  s-s earthquakes give little PGV for an M6, although this whole thing should produce 8's.  Here is a nice picture of the tectonics.

Now it's a strike-slip, which makes sense as it seem to have occured at the Cephalonia (Kefalonia) right-lateral transform: http://www.emsc-csem.org/Earthquake/earthquake.php?id=355461#map, intensities reached VI.
A M5.3 aftershock was widely felt, too, and there are several aftershocks to come.

Yes, apparently thrust is not common there. Also an M6 strike-slip is a weenie with regard to PGV, so there is little damage. Here is a nice link to the tectonics.
