This week´s Centerfault is the famous Arkitsa Fault in Greece (38.43°N, 23.00°E). Along this about 500 m long and locally more than 40 m high excavated limestone fault plane within Mesozoic platform carbonates are uplifted against Pliocene-Quaternary sediments.
This week´s Centerfault is not a single fault or scarp but a very nice view from normal faults in an staircase style in the channel of Corinth (Corinth Canal), Greece (37.55°N, 22.59°E).The image shows the nice faults, which outcrop in the embankments of the channel.

A nice short discussion about the Lorito et al., 2011 paper regarding the seismic gap at the Chilean coast and seismic slip during the 2010 earthquake, can be found at Highly Allochthonous. The discussion highlights the paper findings under the glance of the recent Bio-Bio earthquake from Friday, which took place in this so called Darwin gap.
Today on Friday, 11 February, a magnitude 7.0 earthquake occurred offshore in Chile near Concepcion at 36.5° S and 73° W in a depth of 28km. The MMI at the nearby large cities was reported by the USGS with V.
Update: The magnitude was corrected to 6.8. The earthquake was followed one hour later by a further event with a magnitude of 5.3 and 4 hours later again by a more shallow 6.3.
