摘要：In Slovenia, the large natural geographical units of the Alps, the Dinara Mountains, the Mediterranean, and the Pannonian basin come into contact. There have been many destructive earthquakes in this region in the past. A hundred years ago (1895), a strong earthquake with a magnitude between 8 and 9 on the MCS scale severely damaged Ljubljana. Because Ljubljana is the capital of Slovenia with the largest density of population and numerous important central functions, we consider it the zone most threatened by earthquake. A map of the microseismic zones of Ljubljana has been formulated. With the help of statistical data and other sources, we elaborated a quite detailed data base that we included in the Geographical Information System. This is the first example of such a detailed study in Slovenia, on a city area that includes about 0.9% of Slovenia's territory and 13.4% of its population. The main aim of the study was an assessment of the possible consequences of a destructive earthquake. In the most endangered zone of 9 degrees MCS are 15.23% of all the buildings in which almost 10% of Ljubljana's residents live. The assessment of earthquake vulnerability showed that in an earthquake of magnitude 9, an earthquake stronger than the one in 1895, as much as 26.3% of all the dwellings would be destroyed, and 44.9% of the dwellings would be severely damaged. In less powerful earthquakes, the consequences would naturally be correspondingly smaller.
