I am currently in Greece for field work on faults in the vicinity of Athens. Sascha from RWTH Aachen University is doing his MSc. thesis on remote sensing, geophysical analyses, and mapping of some structures that we think could be active, and me and Ioannis are with him in the field for the first few days. Right on the first day we found some promising outcrops which we will map and check in detail during the next days. This one could be the best so far, it looks like we’ve found a relatively young offset here:
Also, this area is full of beautiful scarps and we will measure some topographic profiles across them and Sascha will try GPR to find out about possible sediment deformation in the hanging wall:
In Athens there have been damages caused by earthquakes repeatedly, but almost always from relatively remote events. Few significant earthquakes in the immediate vicinity of Athens are known in historical times (Ambraseys & Psycharis, 2012), but the landscape around the city is clearly a seismic landscape in terms of Michetti et al. 2005. This is a good reason to check the faults in the surroundings for their activity.

Hi, Saw your article on active faults in athens. Here in Malaysia we are also working on that and it is a relatively new field here .
