Общий статистический анализ многолетних изменений числа дней с градом на фоне изменения климата в Восточной Грузии
No full textModern climate changes can affect the microphysical and electrical properties of clouds, such as the conditions that cause intense hail and lightning. At the same time, the effect of the impact largely depends on the physical-geographical conditions and the ecological situation. It should be noted that global warming that has occurred in recent decades has a significant impact on the dynamics of hail processes.
For the statistical analysis of the number of hail days against the background of modern climate change, the average number of hail days at the stations according to decades was used, which allows to weaken short-term fluctuations and reveal long-term changes. In order to determine the dynamics of hail days in Eastern Georgia, the observation data of some meteorological stations from 1961-2000 and 2014-2020 were analyzed.
In total, the data of 17 meteorological stations of Eastern Georgia about hail for the period of 1961-2020 have been processed.თანამედროვე კლიმატის ცვლილებამ შეიძლება გავლენა მოახდინოს ღრუბლების მიკრო¬ფიზი-კურ და ელექტრულ თვისებებზე, როგორიცაა ძლიერი სეტყვა და ელვის გამომწვევი პირობები. ამასთან, ზემოქმედების ეფექტი დიდწილად დამოკიდებულია ფიზიკურ-გეოგრაფიულ პირობებზე და ეკო¬ლო-გიურ მდგომარეობაზე. აღსანიშნავია, რომ ბოლო ათწლეულების განმავლობაში მომხდარი გლობალური დათბობა მნიშვნელოვან გავლენას ახდენს სეტყვის პროცესების დინამიკაზე.

При этом эффект воздействия во многом зависит от физико-географических условий и экологической обстановки. Следует отметить, что глобальное потепление, произошедшее в последние десятилетия, оказывает существенное влияние на динамику градовых процессов.
Для статистического анализа количества градовых дней на фоне современных изменений климата использовалось среднее количество градовых дней на станциях по десятилетиям, что позволяет ослабить краткосрочные колебания и выявить долгосрочные изменения. Для определения динамики градовых дней в Восточной Грузии были проанализированы данные наблюдений некоторых метеорологических станций за 1961-2000 и 2014-2020 годы.
Всего обработаны данные 17 метеорологических станций Восточной Грузии о граде за период 1961-2020 годы

In particular, on average, for the mean daily values of effective air temperature with the category “Comfortable”, the largest number of days are observed from June to September (15, 18, 17 and 13, respectively). For the maximum daily values of effective temperature - in June, September and October (14, 13 and 12, respectively)

Dynamics of the Aftershock Zone of the 1988 Spitak Earthquake Based on 35 Years of Data
No full textThe features of aftershock manifestations of the 1988 Spitak earthquake have been studied in sufficient detail, but based on data for the first 2-3 years. The aftershock process is divided into highly active (1988-1991) and weakly active (1992 – present) periods. The overwhelming majority of 14,000 aftershocks (95%) and the predominant part of their energy (98%) were released during the active period. During the weakly active period, relative activation is observed in all the identified segments. Against the general background of attenuation of the number and strength of aftershocks, no patterns in their manifestation are observe

From Initial Design to Present Standards: Seismic Sources and Catalogues for the Enguri Dam
No full textThe Enguri High Dam, the highest arch dam in Europe and one of the tallest worldwide (271.5 m), was originally designed in the 20th century for a seismic input corresponding to PGA up to 0.56 g. However, recent probabilistic seismic hazard models developed within the GEM–EMME frameworks suggest higher ground motions, with PGA values approaching 0.9 g [1-2,3]. This discrepancy raises critical questions regarding the robustness of the existing hazard assessments and the seismic safety of the dam.
To address this issue, we initiated a comprehensive investigation combining local and regional seismic data. Spatial clustering of microseismicity allowed us to identify active faults[4]. At the regional scale, we compiled a new unified Georgian earthquake catalogue by merging and harmonizing recently published datasets [5-6]. For consistency, we also evaluated the completeness and derived Gutenberg–Richter parameters for three independent catalogues: new national catalogue, the EMME dataset, and the GEM-ISC compilation. The comparison highlights both commonalities and discrepancies in seismicity rates and recurrence characteristics, which are crucial for subsequent hazard modeling.While the current study focuses on catalogue development, source characterization, and preliminary seismotectonic insights, the next step will be a probabilistic seismic hazard assessment that integrates the refined catalogues and updated source models
The strategic importance and challenges of the eastern coast of the Black Sea, the way to the economic development of Georgia
No full textGeorgia is an important part of the Europe-Caucasus-Asia transport route (TRASECA). For the coastal country, it is an opportunity for economic, maritime, and other economic development. Since ancient times, our country has been connected to Asia and European countries through the Silk Road. In recent years, Georgia's role as a middle corridor connecting countries that do not have access to the Black Sea (Azerbaijan, Armenia, and Kazakhstan) has significantly increased. The construction and development of the "Anaklia Deep-Sea Port" will contribute to the development of Georgia as a transport and logistics hub.
“The Black Sea Submarine Cable” project is a project of strategic importance and offers great opportunities for Georgia, Romania, and other neighboring countries. The project aims to export energy from the South Caucasus (SC) countries to Romania, Bulgaria, and South-Eastern Europe (SEE) via a submarine cable crossing the Black Sea. It will support the development of the renewable energy sector, increase transit opportunities between Georgia and the European Union.
The purpose of our research is to find out what economic and political benefits our country will receive in the case of the implementation of these two important projects. How attractive and profitable Georgia can become as an economy if this project is implemented. We will also assess the current situation and challenges of the eastern coast of the Black Sea
