## 3 ETL Inventory in Cephalonia Island  
### Recent Studies on Landslide Inventory in Greece  
The research for the systematic inventory of landslides in Greece is not so widespread. It mainly includes studies presenting maps with landslides throughout Greece [45; 46; 47; 48; 49] and maps of landslide-affected settlements [50] as well as several studies with results from field reconnaissance surveys in several earthquake- and landslide-affected areas, where ETL are reported and recorded among other effects. The first attempt for the development of a complete recording system of the landslides in Greece was made by [PERSON] and [PERSON] [45]. They conducted a statistical analysis on 800 case histories of landslides in Greece from 1949 to 1986. The related information was retrieved from 1500 coded engineering reports and studies conducted by different public corporations including the Hellenic Authority of Geological and Mining Research (former Institute of Geology and Mineral Exploration of Greece) and the Central Union of Greek Municipalities. Their study includes cases in villages and their surroundings as well as along the road network and refers to the landslide frequency distribution and their consequences on different geological formations, altitudes, rainfall, slope angle, etc., while certain interrelations were studied and an engineering geological map as well as landslide distribution and frequency zone maps were compiled. A similar approach was followed by [PERSON] et al. [46], who further evaluated data from 1116 case histories of landslides from 1949 to 1991, expanding the dataset of [PERSON] and [PERSON] [45]. They investigated the frequency distribution of landslide control parameters, and their results were presented in tables and graphs. Analogous extensions of the number of landslides and the time period and update of the results of the statistical analysis were conducted by [PERSON] et al. [47] with 1200 landslides from 1949 to 1995, by [PERSON] et al. [48] with 1300 landslides from 1950 to 2004 and by [PERSON] et al. [49] with 1635 landslides up to 2010. The landslide inventory map of Greece [50] and the above works present the landslide locations, but no additional qualitative or quantitative characteristics of the landslides, or information on their causes and time of occurrence. As a result of this approach, the marked landslides could not be associated with specific triggering events, e.g., earthquakes, rainfall or even human activity. For the ETL in Greece in general and for the Cephalonia in particular, the maps of the above studies are not significantly useful as it is not possible to determine whether the eight recorded landslides on the island were caused by earthquakes or rainfall or another triggering factor. Furthermore, [PERSON] and [PERSON] [17] collected data on 47 landslides induced by earthquakes from 1650 to 1995 with magnitude ranging from 5.3 to 7.9. Based on the ETL data, they presented magnitude-distance relations for ETL in Greece, which are compatible with curves proposed worldwide. They also examined the spatial distribution of ETL, the size distribution, and the maximum landslide distance from the epicenter. However, the collected data was not sufficient or accurate to be used for studying other parameters, such as the area affected by landslides and correlation with earthquake magnitude, as well as the minimum intensity for generating ETL. According to [PERSON] and [PERSON] [17], the historical descriptions of ETL in Greece are usually not precise enough to provide a reliable basis for a modern scientific analysis. Furthermore, after examining hundreds of documents, they supported that a database with data from the 16 th century onwards can be exploited.
