Vajont landslide, which affected the northern slope of Monte Toc in the Dolomites (NW Italy), is one of the most famous examples of a natural disaster induced by human activity. A wave, generated by displaced material that filled the Vajont reservoir, overtopped the dam and destroyed a few villages in the nearby Piave valley, resulting in death of approximately 2000people. In this review paper, some facts about the disaster are presented and its triggering factors are discussed. Information related to tourism development in the area is also provided.

The paper provides a description of primary geological logs, characteristics and formal lithostratigraphy of the uppermost Emsian and lower Eifelian of the Kielce Region of the Holy Cross Mts., central Poland. Nine sections of this interval, representing the whole area of the Kielce Region, and ranging between the Lower Devonian clastics of the Winna Formation and the Middle Devonian carbonates of the Kowala Formation were studied. The succession is divided into the Barania Góra Dolomite and Limestone Formation and the Wojciechowice Dolomite Formation. Six members are distinguished within the former. In the western part of the region these are (in stratigraphical order): Porzecze Claystone Member, Dębska Wola Dolomite Member, Dąbrowa Limestone Member, and Brzeziny Dolomite Member. In the eastern part, the formation is divided into the Janczyce Dolomite Member and the Jurkowice Dolomite Member. Additionally, the Wszachów Dolomite Member and Nowy Staw Dolomite Member are distinguished within the overlying Wojciechowice Formation. The thickness of the uppermost Emsian–Eifelian succession ranges from ca. 200 m in the eastern part to ca. 130 m in the western part of the Kielce Region.

Marian Smoluchowski (1872-1917) was an eminent physicist of international renown. His research in the field of the Kinetic Theory of Matter (e.g. the Brownian motion) contributed to strengthen the nuclear science. He is considered a pioneer of the statistical physics. Childhood and the years of study he spent in Vienna. From an early age, he was associated with mountains and was a prominent mountaineer. Along with his brother, Tadeusz, he climbed many unclimbed peaks in the Eastern Alps: Dolomites, Ortler group and Hohe Tauern. Those achievements passed into the history of Alpine mountaineering. In addition to sports and aesthetic aspects (he painted mountain landscapes), Smoluchowski found his scientific inspirations in the mountains. He was interested in the mechanics of tectonic movements and joined the discussion on the concepts concerning the nappe structure of orogens at the beginning of the 20th century (1909). Research on the physicalfoundations of tectonic movements in the Tatra Mountains, that he planned to undertake, was thwarted by the outbreak of World War I in 1914, and his premature death in 1917.

New stratigraphic and palaeoenvironmental data are presented for the northeastern part of the Trento Plateau (Puez area, Southern Alps, Italy). The studied section corresponds to the upper Hauterivian Balearites balearis and "Pseudothurmannia ohmi" ammonite zones and normal palaeomagnetic chron upper M5. A c. 30-cm-thick bed is identified as the equivalent of the Faraoni Level, based on its position within the Pseudothurmannia mortilleti Subzone, the composition of its ammonite fauna and the peak of a minor positive trend in the [delta]13 Cbulk record. Microfacies and geochemical proxies compare well with those of the southeastern part of the Trento Plateau and indicate palaeoceanographic continuity along the eastern margin of the plateau. The abundances of radiolarians and nannoconids suggest a turnover in the trophic structure from eutrophic conditions around the Faraoni Level equivalent to oligotrophic conditions. Low organic matter and sulphur content and frequent bioturbation indicate a well-oxygenated environment. Ammonite diversity and life-habitat groups document the influence of sea level on the plateau: while epi- and mesopelagic ammonites occur commonly during sea-level highstands, all life-habitat groups become reduced during a sea-level lowstand in the Spathicrioceras seitzi and P. ohmi subzones. The Faraoni event is heralded by a faunal turnover expressed as the diversification of epipelagic ammonites. Palaeoenvironmental conditions along the eastern margin of the Trento Plateau during the Faraoni event contrast with those of the organic-rich black shales in the west. A re-evaluation of the depositional model based on the new results suggests a general water depth of 300-500 m for the plateau. The severe reduction of mesopelagic ammonites during the sea-level lowstand indicates a shallowing towards the epi-/mesopelagic boundary. During the Faraoni event, the eastern areas of the Trento Plateau were located at the upper limit of the oxygen-minimum layer and were thus only occasionally affected by oxygen depletion, whereas the western areas were located well within the upper part of the oxygen-depleted layer.
