The 1998 Krn Mountains earthquake with a maximum intensity of VII-VIII on the EMS-98 scale caused extensive environmental effects in the Julian Alps. The application of intensity scales based mainly on damage to buildings was limited in the epicentral area, because it is a high mountain sparsely populated area. On the other hand the effects on the natural environment were prominent and widespread. These facts and the introduction of a new ESI 2007 scale motivated a research aimed to evaluate its applicability to this event. All environmental effects - rockfalls, landslides, secondary ground cracks and hydrogeological effects - were described, classified and evaluated by a field survey, analysis of aerial images and macroseismic questionnaires. It was realized that only rockfalls (78 were registered) are widespread enough to be used for intensity assessment, together with the total size of affected area. They were classified into five categories according to their volume. Distribution of very large, large and medium size rockfalls has clearly defined an elliptical zone, elongated parallel to the strike of the seismogenic fault, for which the intensity VII-VIII was assessed. This isoseismal line was compared to the EMS-98 isoseism derived from damage-related macroseismic data and a similar shape was obtained. The ESI 2007 scale has proved to be an effective tool for intensity assessment in sparsely populated mountain regions not only for very strong, but for moderate earthquakes as well.

An analysis of antecedent rainfall and the rainfall total on the given day revealed a distinct relationship between the rainfall patterns and landslide events, in the study area Škofjeloško Cerkljansko hills. Landsliding is seen to be generally related to the amount of rainfall in a certain period over which accumulated rainfall initiates a slope failure. Therefore, based on the available data of rainfall events and landslides and their occurrence from 1990 to 2010, two distinct antecedent periods are suggested. It was found that shallow landslides have been initiated by intense short and long duration rainfall.

The Carnian carbonate succession in the Mežica area called “Raibl Beds” (Karavanke Mts, Slovenia) includes three clastic horizons of marly–shaly rocks. Only one single sample yielded well preserved Carnian (Julian) conodonts. The monospecific conodont fauna is marked by elements of Nicoraella ? budaensis that enables us to reconstruct a multielemental apparatus. The recovered conodont fauna verifies the Julian age of the second clastic horizon in the Mežica area and it provides new significant information for definition of the Carnian Pluvial Event in the Karavanke Mts.

The monograph was written by specialists from every national institution working in the field of geology. In more than 600 pages, a comprehensive summary of the discoveries made by geologists in Slovenia has been systematically compiled for the first time. This book forms basic reading on the geology of Slovenia for experts, students and nature lovers involved in researching the Earth's lithosphere. The bilingual edition enables one to combine more easily the data relating to the geology of Slovenia with the broader European and international community. Member of the PG Matevž Novak was one of the three editors and technical editor of the first monograph on geology of Slovenia. Members of the PG are authors or co-authors of 6 out of 12 chapters in the monograph. According to very positive response of the professional public as well as of the general public, the monograph is a monumental piece of high quality work.

We studied well exposed Middle Triassic (Anisian – Ladinian) sections in the Julian Alps (Mt. Prisojnik) and in KamnikSavinja Alps (Mt. Križevnik and Mt. Ute). In the Upper Anisian, start of the tectonic movements, extensional rotation of blocks triggered formation of the smallscale and limited halfgrabens, filled with material from the tectonically predisposed footwall escarpments. Volcanism associated this turbulent environment. Coevally, red pelagic limestones with rich radiolarian and conodont fauna deposited, which enabled us precise datations of event and consequently installed it in the broader paleogeography of the Southern Alps.
