Abstract
The paper gives a short overview of the historical earthquakes on the territory of Slovenia since AD 792, with the 1511 Idrija Earthquake (MM = 6.8 ± 0.3) as the strongest earthquake in this record. Firstly, seismotectonic characteristics of Slovenia are presented together with the seismological map of Slovenia. Secondly, a national landslide database and landslide occurrence map (cadastre) is discussed. Furthermore, different (statistical) models are presented that have been used to prepare landslide (also debris flows and rock falls) susceptibility maps of Slovenia at scale 1:250,000. The role of earthquakes as triggering factors in these models is discussed. Moreover, a field case study is discussed; the conclusions reached by the analysis of the numerous rock falls initiated during the 1998 Posočje earthquake (ML = 5.6; the strongest earthquake in the 20th century with the epicenter in the territory of Slovenia) and the 2004 Posočje earthquake (MLV = 4.9) is presented. A short final section on legislative framework in Slovenia with regard to hazard and risk mapping of slope instabilities respectively mass movements (including earthquake-induced landslides) is given.
