In the middle of the XX century a small ravine emerged on the Yana Plateau in the Batagaika River valey. It began to grow rapidly and by now has turned into a huge thermokarst depression, which is now called the Batagai Crater. Its emergence was favored by a combination of factors, both natural and anthropogenic origin

Recent advances in the development of super-power lasers are reviewed. A number of possibilities that the newly available petawatt power level lasers open up in the physics of extreme light éelds are discussed.

We proposed to use multipetawatt multibeam systems that reproduce a dipole wave of the electric configuration to maximise the electric field in the interaction region and the energy of accelerated particles. The breakdown of vacuum in fields of this configuration leads to the formation of beams of electrons and positrons accelerated to several GeV. It is shown that when use is made of 12 laser pulses with a duration of 30 fs and a total power of 36 PW, the total charge of accelerated electrons (positrons) can reach 250-270 nC, and the charge of particles with energies above 1 GeV can exceed 1 nC. It is demonstrated that the electric dipole structure of the fields makes it possible to obtain an extremely narrow (several mrad) distribution of particles over the polar angle measured from the field symmetry axis. It is also shown that the distribution of particles over the azimuthal angle can be used to diagnose interaction regimes during vacuum breakdown. The obtained results can be useful in preparing experiments on the promising XCELS laser system.

Currently, the scienti c community faces the task of identifying and minimizing the negative impact on the natural environment and related environmental risks caused by the impact on ecosystems, especially anthropogenic factors related environmental risks. The determining role in the assessment of environmental risk is to determine the probability of occurrence of effects of different nature in ecosystems because of anthropogenic factors and to take measures to prevent their negative impact. The purpose of the presented theoretical study was to study and analyze the principle of system-wide methodology of quantitative assessment of biogeocenosis quality within the boundaries of anthropogenic in uence on the sustainability of industrially developed territory. The considered principle can provide prerequisites for making changes in the norms of nature management in Russia.

Within early warning and technological hazards, the need to notify, and to identify, assess and provide the necessary information about the sources of potential hazards is of particular importance. Since there may be causal links between natural and technological disasters, there are increasing concerns that the available knowledge base does not allow for timely warning or relief measures for many hazards. Any early warning system aims to reduce risk as a measure of potential environmental and economic damage. Such reduction, as a rule, is achieved by continuous study of information on the state of functioning of the natural-technical system. Hence the task of systematic collection, accumulation, processing and analysis of information arises. The system of continuous observation, control and analysis of the environmental situation for subsequent diagnosis and forecasting of the state of natural objects is realized within the framework of monitoring, which is performed at three levels - global (planetary), regional and local. The Sakha Republic (Yakutia) is the largest region of the Russian Federation with a highly concentrated natural-resource potential, providing full-scale projects of national economic development of interregional and federal signi cance. Yakutia, the area of which is 20 % of Russia’s territory, is a giant natural enclave in geotechnical terms, the administrative boundaries of which cross many geographically heterogeneous ecosystems of seven neighboring territories (administratively independent subjects of ownership). The article considers and reveals the main directions of the early warning system to prevent socio-natural risk as applied to Yakutia, taking into account its natural-territorial uniqueness.

Extratropical cyclones over the Sakha Republic (Yakutia) bring rains and reduce the probability of forest res, but can cause fast rain ood events caused by heavy precipitation. In this study, recurrence of cyclonic events over the Sakha Republic (Yakutia) in summer months between 1950 and 2022 is considered. Recurrence of cyclonic events was de ned as the count of cyclone centers over Yakutia or subregions at a standard time of observations. Extratropical cyclone centers database from University of Manitoba (Canada) based on ERA5 reanalysis was used in this study. Cyclonic weather over the territory of the Sakha Republic (Yakutia) persists for 27.5 days on average. The largest count of cyclonic events is noted in the North-Eastern and North-Western sub-regions, while the smallest is in the Southern and Central sub-regions. Across summer months, cyclones are most active in June in all regions except for the Southern sub-region. Here, increased July cyclonic activity is determined by conditions favorable for atmospheric blocking, limited zonal transport promoting the northward intrusion of southern cyclones. There is no pronounced trend in the frequency of occurrence of cyclones except for some regions and months: Western Area, June, increasing; the Sakha Republic (Yakutia), August, decreasing. An absolute minimum in the number of cyclonic events was established for 2019-2021, which, as we believe, was one of the main reasons for the maximum of forest re activity in the Sakha Republic (Yakutia) observed in these years, along with the Lena River extremely low ows of 2019. An analysis of the circulation conditions leading to such extremes will make it possible to assess the risk of recurrence of similar situations under the future climate.

The article provides an analytical review of the results of direct geochemical studies of the Vilyui syneclise, one of the promising areas for oil and gas in the east of the Siberian Platform. The work objective is to demonstrate the high ef ciency of direct geochemical sampling for the search for oil and gas deposits in the conditions of a terrigenous section of the studied territory. It is shown that pro le contrast anomalies were identi ed above productive structures. At the same time, a general increase of light hydrocarbon (LH) components from the anks to its center and the con nedness of the most noticeable microconcentrations of heavy hydrocarbons (HH) to the periclinal sections of productive structures have been established. This phenomenon, apparently, indicates the predominant effect of ltration migration through various weakened zones from the source of hydrocarbons (deposits). The results of our own reconnaissance work carried out in 2016 on the southern pericline of the Middle-Vilyui gas condensate deposit are presented. The veri cation work was carried out to evaluate the effectiveness of the equipment and research methods. Relatively high values of benzene and toluene were recorded above the zones of occurrence of deposits T1-IIа and T1-III. It is assumed that the maximum values of B/T can be con ned to the zones of oil accumulations. Based on the conducted geochemical samplings and historical experience, it is concluded that in combination with other geological and geophysical methods, direct geochemical studies will increase the reliability of forecasting the prospects of oil and gas potential of poorly studied territories. A recommendation has been made for the use of geochemical samplings in adjacent territories with a similar geological section.
