This work is a multi-disciplinary research aimed to develop common approaches to estimating the current state and forecasting evolution of coastal geosystems. From 2010 to now, the state of coastal zone geosystems of the Crimean and Caucasian Russian coast has been studied. The research tasks are solved using up-to-date IT based integrated analysis of historical and new observational data.

Explosive volcanic eruptions pose certain danger for natural environment, transport communications and other objects of human economic activity due to the fact that during such eruptions, up to several cubic kilometers of volcanic ash and aerosols can enter to atmosphere in long time. The research of extent of the impact of volcanic eruptions on surrounding area and the determination of their consequences contributes to reasonable assessment of volcanic hazard and possible risks in time conduct of economic activities and ensuring for safe location of settlements, enterprises, sea way and air lines. Chikurachki volcano is one from most active on territory of the Kuril Island Arc. In articles of volcanologists is information about eruptions in 1853–1859, 1958, 1961, 1964, 1973, 1986, 2002, 2003, 2005, 2007, 2008, 2015, 2016. The vegetation index (NDVI) used as means of assessing state of the natural environment. The boundary dividing areas with disturbed and healthy vegetation cover taken along isoline with NDVI value of 0.4. Schematic maps of the dynamics of boundary isolines according for the vegetation index from 1972 to 2020 has been compiled. The dynamics of vegetation cover in the north-eastern, south-eastern and southern sectors relative to Chikurachki volcano is revealed. The north-eastern sector experienced strong negative impact of eruption of the Chikurachki volcano in 1853, at later (2007 and 2015) only ash falls were observed in this direction. The vegetation cover outside the isoline NDVI = 0.4 has almost completely recovered to 2020. The south-eastern sector damaged during eruption of 1986, and was also subject for periodic tephra precipitation and ash falls during 2002–2016. Vegetation was completely destroyed at distance of 9 km from the crater of the volcano, and also valley forests on Tukharka River were destroyed. In southern sector in upper part of the Vernadsky Ridge, harsh growing conditions do not allow vegetation to recover for decades. At the same time, on eastern and western slopes of the ridge, after eruptions with deposition of tephra by layer of small thickness, alder elfin restoration few years. The results of the recearch can be used in forecasting volcanic hazards and rapid assessment of impact on natural environment of territories adjacent to volcanoes of this type as a result of volcanic eruptions.

Byzantine Constantinople was structured upon arcaded streets of shops, or emboloi, and formal public fora, which usually served the purpose of housing various kinds of markets. The largest and perhaps oldest of these was the Strategion, which consisted of two courts that were adjacent to the inlet of the Golden Horn, and the Neorian and Prosphorian harbours giving access to the Bosphorus, and thus to the Mediterranean and Black Seas, in the period up to the seventh century. However, the exact location and scale of the Strategion has not yet been determined, and the location of the streets connecting from the central Mese road to the Strategion has been the matter of debate. In this paper, I shall examine field drawings executed by the Swiss archaeologist Ernest Mamboury in the 1920s of building foundations uncovered during council canalization works for the new sewer system in Istanbul, in order to propose a new layout of the street system in the north-eastern sector of Byzantine Constantinople leading to the Strategion. The paper is based upon analysis of digital maps that place the found remains in relation to site contours, modern and existing Byzantine buildings, and current streets. Notably, the study locates what appear to be two major streets with what appear to be shops and courtyards aligned along them. These streets will be reconciled with known buildings and structures, such as the Milion, and churches of St Sophia and St Mary Chalkoprateia. I shall argue that locating the streets has enabled determination of the entrance to the forum, and thus adds to knowledge of the topographical layout of this district of Constantinople.

The article presents data concerning prevalence of sarmidosis in Tomsk and the Tomsk region for 16 years and impacting of ecological and geochemical factors (elemental composite of incrustation of snow, soils) on disease. The sarmidosis morbidity of individuals without undergoing impact of occupational hazards is reliably higher in areas with increased anthropogenic loading (the Oktiabrskii district of Tomsk, the Tomsk rural district, the North- Eastern sector, city of Seversk, Parabelskii and Kolpashevskii districts, Strejevoii). The positive associations were established between sarmidosis morbidity and content of sodium in incrustation of snow, cerium in soil. The sarmidosis with severe recurrent course correlated positively with lutetium and chrome of soils and negatively with barium in incrustation of snow.

TheRānī Pokhrī (Queen Lake) is situated at the northern end of the Ṭuṇḍkhel, the large parade ground of Kāṭhmāṇḍu, and near Kamalāchiṭol, the north-eastern sector of the town. The lake is rectangular in shape, and the lines of its banks run roughly north-south and east-west. In the middle of the lake is a Śaivite temple, which is connected to the western bank by a straight causeway. A few years ago the lake was enclosed by a high metal fence, built some ten yards back from the edge of the water.
