On 26 January and 3 February, two strong and shallow earthquakes of magnitude 6+ occured at the island of Kefalonia/Cephalonia in Western Greece. The events caused intense damage to buildings and infrastructure. A team of EERI (Earthquake Engineering Research Institute) scientists went to the island to map these kind of damages. Earthquake Environmental Effects (EEE) like rockfalls, landslides, and lateral spreading were also caused by the events. George Papathanassiou and his colleagues mapped these features and sent me the following photos from Lixouri.

George told me that they are currently mapping the EEEs using their Earthquake Geosurvey App, which was released recently and presented during the 4th PATA Days conference in Aachen.

Up to now, hundreds of aftershocks took place in Cephalonia, some of which were strong enough to be felt widely.
