Analyzing the seismic hazards of the Crimea and North Caucasus and adapting the obtained assessments to the GSZ-2014 set of maps . . .12

This article is a continuation of papers on improving the general seismic zonation (GSZ) of the Russian Federation territory. Particular attention is paid to assessing seismic hazards of the Crimea and North Caucasus and adapting the obtained results to the GSZ-2014 (OSR-2014) set of maps. The developed new approaches to the zonation technology made it possible to assess the seismic hazard degree of the Crimean-North-Caucasian region and to single out its zones with various earthquake intensities for the normative repeatability periods of 500, 1000 and 5000 years more objectively.

Key words: earthquake; seismic geodynamics; seismic hazard; general seismic zonation; Crimea; North Caucasus; GSZ-2014 (OSR-2014) set of maps.

The role of soil liquefaction in macroseismic consequences of strong earthquakes  . . .28

The paper considers some features of damages of buildings and structures revealed at macroseismic surveys of the consequences of the Spitak (Armenia, 1988), Neftegorsk (Sakhalin, 1995), Chuya (Bel’tir, Altai, 2003) and Olyutor (Korf, Kamchatka, 2006) earthquakes. Particular attention is paid to increasing the damages and destructions of buildings and structures within the epicentral areas due to soil liquefaction at those strong earthquakes. The author considers that it is necessary to take into account such effects when constructing seismic zoning maps.

Key words: strong earthquakes; macroseismic consequences; soil liquefaction; land subsidence; fissures; degree of damage; Spitak; Neftegorsk; Bel’tir; Korf.

Domestic and international experience of studying weathered rocks and eluvial soils for engineering-geological purposes . . .34

The article deals with the domestic and international experience of studying weathered rocks and eluvial soils. Classifications of division of the weathering crust into zones are presented. The causes of spatial variability of physical-mechanical properties of weathered rocks and eluvial soils are analyzed. Similarities and differences between investigations of weathering products in various countries are established.

Key words: weathering; eluvial soils; weathering profile; classification schemes; variability of physical-mechanical properties; weathered rocks and eluvial soils; disintegration; geochemical zonality.

On features of the Hoek-Brown rock behavior model and determining its initial parameters  . . .42

The article considers the features of the Hoek-Brown rock behavior model, its advantages and disadvantages. The initial parameters of the model are analyzed. Their physical meanings and assignment mechanisms are described. Possible errors and inaccuracies of their determination due to different methodological approaches to the investigations abroad and in our country are pointed out. It is shown that determination of the initial parameters for the Hoek-Brown model is possible if the requirements of the normative documents of the Russian Federation are satisfied. At that, it is necessary to analyze the obtained data in accordance with the features of E. Hoek’s method.

Key words: numerical simulation; rock; empirical model; Hoek-Brown model; initial parameters of the Hoek-Brown model; geological strength index (GSI); classification of rocks by the geological strength index (GSI).

Features of reclamation of oil-polluted areas in the western Siberian Conditions . . .48

The article substantiates the need to change the existing approaches to reclamation of oil-polluted areas by the example of a number of oil fields in Western Siberia. The authors show that application of bacterial preparations in the natural-climatic conditions of this region does not permit to realize effective reclamation but rather promotes burial of the oil pollution in the soil strata lying below the specified sampling depth. In this connection, soil sampling from the depth of more than 0.5 m is required at the biological reclamation stage using bacterial preparations. Besides that, reclamation of areas polluted by oil longer than 4–5 years is untenable from the ecological-geological positions. These circumstances should be taken into account at planning programs of reclamation of oil-polluted territories.

Key words: oil pollution; territory reclamation system; bacterial preparations; territory self-regeneration; ecological-geological estimation.

Search of microspheres in an ash disposal area by the methods of electrical resistivity tomography and electromagnetic profiling . . .58

The goal of the presented survey was development of a technique for search of microspheres (gas-filled aluminosilicate microballs forming at coal combustion) using geoelectrical methods at a site in the ash disposal area of the Tom’-Usinsk state district power station (Kemerovo Region) which is promising for microspheres extraction. Two methods of electrical prospecting were used, namely electrical resistivity tomography and electromagnetic profiling. As a result, correlation between the microspheres concentration and electrical resistivity of the medium was found at the qualitative level.

Key words: electrical resistivity tomography; electromagnetic profiling; ash disposal area; microspheres; Tom’-Usinsk state district power station.

Assessment of the state of lithotechnical systems of historical-cultural structures for substantiation and realization of their monitoring . . .62

The article discusses assessment of the state of lithotehnical systems relating to historical-cultural buildings (HLTS) in the context of analysis of their functioning sustainability. The most significant aspects of the sustainability such as the spatial, temporal, mechanical, geodynamical, microclimatic, microbiological, ecological-geological, historical-look-stability ones are considered. The authors single out categories of the state of historical-cultural buildings. These categories allow to characterize HLTS comprehensively. On the basis of this characteristic the composition and time schedule of the observations and investigations in the HLTS monitoring framework can be substantiated.

Key words: monitoring; lithotechnical system (LTS); historical-cultural ithotechnical system (HLTS); sustainability of functioning; state.

Ecological geology: theory, practice and regional problems: The fourth international research and practice conference  . . .70

The report briefly describes the 4-th International Research and Practice Conference “Ecological geology: theory, practice and regional problems” held in the city of Petrozavodsk from 30 September to 2 October 2015.

Key words: ecological geology; research and practice conference; Petrozavodsk city.
