    Predictive estimates of the number of hail days (HD) and their moving averages (for 3, 5, 7, 9 and 11 years โ€“ HD_3โ€ฆHD_11) per warm period of year to 2050 and 2085 an example of Tbilisi was performed. Forecasting was carried out using the AAA version of the exponential smoothing (ETS) algorithm taking into account the periodicity in the pre-forecast time series. In particular, the following results were obtained. For the time series of the measured number of days with hail and HD_11 years, no pronounced peak in periodicity is observed. For time series HD_3, the periodicity is 14 years, HD_5 โ€“ 32 years, HD_7 and HD_9 โ€“ 31 years. In the period from 2022 to 2050, the range of variability of the average values of the central points of the forecast for the number of days with hail and the values of their 95% upper level is as follows: HD - from 0.9 to 3.8, HD_3 - from 1.0 to 3.0, HD_11 โ€“ from 1.0 to 1.6. In the period from 2022 to 2085, the range of variability of the average values of the central points of the forecast for the number of days with hail and the values of their 95% upper level is as follows: HD_5 - from 0.4 to 3.0, HD_7 - from 0.7 to 1.8, HD_9 - from 0.5 to 3

    A statistical analysis of data on number of days with hail (annual and for period from April to October) in 43 locations of Georgia in 2006-2021 are presented. In particular, the following results are obtained. The max average annual number of days with hail in Akhaltsikhe is observed (3.4). The max annual number of days with hail in Mirveti is observed (16). The max average number of days with hail in warm period in Akhaltsikhe also is observed (3.3). The max number of days with hail in warm period in Khashuri is observed (9). The climate change influence on the number of days with hail during the warm period has been studied. Comparison of the number of days with hail for 30 meteorological stations in 2006-2021 and 1941-1990 showed that in the second period of time, compared to the first period, the number of days with hail at the 18 stations decreased, at the 10 stations - did not change, and increased at only one station (Keda). The data of this work will be used to compile a Natural Hazards Catalog in Georgia

    In the book a new synthesis of 44 earthquakes for each of which parameters such as date, location, magnitude and focal depth are summarized. The detailed description of the individual earthquakes enables the reader, on the bases of citations of historical descriptions, to obtain an overview on basic quantities of information used for individual events. Furthermore, the reasoning for the individual intensity classification is justified. The total compilation of these data leads to an improved map of the maximum damage distribution for historical earthquakes in Georgia, which is important as contribution to modern seismic hazard and risk assessment.แƒฌแƒ˜แƒ แƒœแƒจแƒ˜ แƒฌแƒแƒ แƒ›แƒแƒ“แƒ’แƒ”แƒœแƒ˜แƒšแƒ˜แƒ 44 แƒ›แƒ˜แƒฌแƒ˜แƒกแƒซแƒ•แƒ แƒ˜แƒก แƒแƒฎแƒแƒšแƒ˜ แƒ’แƒแƒœแƒ–แƒแƒ’แƒแƒ“แƒแƒ”แƒ‘แƒ แƒ“แƒ แƒ›แƒแƒ—แƒ—แƒ•แƒ˜แƒก แƒ“แƒแƒ“แƒ’แƒ”แƒœแƒ˜แƒšแƒ˜แƒ แƒ˜แƒกแƒ”แƒ—แƒ˜ แƒžแƒแƒ แƒแƒ›แƒ”แƒขแƒ แƒ”แƒ‘แƒ˜, แƒ แƒแƒ’แƒแƒ แƒ˜แƒชแƒแƒ แƒ—แƒแƒ แƒ˜แƒฆแƒ˜, แƒแƒ“แƒ’แƒ˜แƒšแƒ›แƒ“แƒ”แƒ‘แƒแƒ แƒ”แƒแƒ‘แƒ, แƒ›แƒแƒ’แƒœแƒ˜แƒขแƒฃแƒ“แƒ, แƒ™แƒ”แƒ แƒ˜แƒก แƒกแƒ˜แƒฆแƒ แƒ›แƒ”. แƒ˜แƒœแƒ“แƒ˜แƒ•แƒ˜แƒ“แƒฃแƒแƒšแƒฃแƒ แƒ˜ แƒ›แƒ˜แƒฌแƒ˜แƒกแƒซแƒ•แƒ แƒ”แƒ‘แƒ˜แƒก แƒ“แƒ”แƒขแƒแƒšแƒฃแƒ แƒ˜ แƒแƒฆแƒฌแƒ”แƒ แƒ แƒ›แƒ™แƒ˜แƒ—แƒฎแƒ•แƒ”แƒšแƒก แƒแƒซแƒšแƒ”แƒ•แƒก แƒกแƒแƒจแƒฃแƒแƒšแƒ”แƒ‘แƒแƒก, แƒ˜แƒกแƒขแƒแƒ แƒ˜แƒฃแƒšแƒ˜ แƒแƒฆแƒฌแƒ”แƒ แƒ”แƒ‘แƒ˜แƒก แƒชแƒ˜แƒขแƒแƒขแƒ”แƒ‘แƒ˜แƒก แƒกแƒแƒคแƒฃแƒซแƒ•แƒ”แƒšแƒ–แƒ”, แƒ›แƒ˜แƒ˜แƒฆแƒแƒก แƒ–แƒแƒ’แƒแƒ“แƒ˜ แƒฌแƒแƒ แƒ›แƒแƒ“แƒ’แƒ”แƒœแƒ แƒซแƒ˜แƒ แƒ˜แƒ—แƒแƒ“แƒ˜ แƒ˜แƒœแƒคแƒแƒ แƒ›แƒแƒชแƒ˜แƒ˜แƒก แƒ›แƒแƒชแƒฃแƒšแƒแƒ‘แƒ˜แƒก แƒจแƒ”แƒกแƒแƒฎแƒ”แƒ‘, แƒ แƒแƒ›แƒ”แƒšแƒ˜แƒช แƒ˜แƒงแƒ แƒ’แƒแƒ›แƒแƒงแƒ”แƒœแƒ”แƒ‘แƒฃแƒšแƒ˜ แƒ˜แƒœแƒ“แƒ˜แƒ•แƒ˜แƒ“แƒฃแƒแƒšแƒฃแƒ แƒ˜ แƒ›แƒแƒ•แƒšแƒ”แƒœแƒ”แƒ‘แƒ˜แƒกแƒ—แƒ•แƒ˜แƒก. แƒ’แƒแƒ แƒ“แƒ แƒแƒ›แƒ˜แƒกแƒ, แƒ›แƒแƒชแƒ”แƒ›แƒฃแƒšแƒ˜แƒ แƒ“แƒแƒกแƒแƒ‘แƒฃแƒ—แƒ”แƒ‘แƒฃแƒšแƒ˜ แƒ›แƒกแƒฏแƒ”แƒšแƒแƒ‘แƒ แƒชแƒแƒšแƒ™แƒ”แƒฃแƒšแƒ˜ แƒ›แƒแƒ•แƒšแƒ”แƒœแƒ˜แƒก แƒ˜แƒœแƒขแƒ”แƒœแƒกแƒ˜แƒแƒ‘แƒ˜แƒก แƒ™แƒšแƒแƒกแƒ˜แƒคแƒ˜แƒ™แƒแƒชแƒ˜แƒ˜แƒก แƒจแƒ”แƒกแƒแƒฎแƒ”แƒ‘. แƒแƒ› แƒ›แƒแƒœแƒแƒชแƒ”แƒ›แƒ”แƒ‘แƒ˜แƒก แƒ’แƒแƒœแƒ–แƒแƒ’แƒแƒ“แƒแƒ”แƒ‘แƒ แƒกแƒแƒจแƒฃแƒแƒšแƒ”แƒ‘แƒแƒก แƒ˜แƒซแƒšแƒ”แƒ•แƒ แƒแƒ˜แƒ’แƒแƒก แƒกแƒแƒฅแƒแƒ แƒ—แƒ•แƒ”แƒšแƒแƒจแƒ˜ แƒ˜แƒกแƒขแƒแƒ แƒ˜แƒฃแƒšแƒ˜ แƒ›แƒ˜แƒฌแƒ˜แƒกแƒซแƒ•แƒ แƒ”แƒ‘แƒ˜แƒ— แƒ’แƒแƒ›แƒแƒฌแƒ•แƒ”แƒฃแƒšแƒ˜ แƒ›แƒแƒฅแƒกแƒ˜แƒ›แƒแƒšแƒฃแƒ แƒ˜ แƒ“แƒแƒ–แƒ˜แƒแƒœแƒ”แƒ‘แƒ”แƒ‘แƒ˜แƒก แƒ’แƒแƒœแƒแƒฌแƒ˜แƒšแƒ”แƒ‘แƒ˜แƒก แƒ’แƒแƒฃแƒ›แƒฏแƒแƒ‘แƒ”แƒกแƒ”แƒ‘แƒฃแƒšแƒ˜ แƒ แƒฃแƒ™แƒ, แƒ แƒแƒ›แƒ”แƒšแƒกแƒแƒช แƒ›แƒœแƒ˜แƒจแƒ•แƒœแƒ”แƒšแƒแƒ•แƒแƒœแƒ˜ แƒฌแƒ•แƒšแƒ˜แƒšแƒ˜ แƒจแƒ”แƒแƒฅแƒ•แƒก แƒ—แƒแƒœแƒแƒ›แƒ”แƒ“แƒ แƒแƒ•แƒ” แƒกแƒ”แƒ˜แƒกแƒ›แƒฃแƒ แƒ˜ แƒกแƒแƒจแƒ˜แƒจแƒ แƒแƒ”แƒ‘แƒ˜แƒก แƒ“แƒ แƒ แƒ˜แƒกแƒ™แƒ˜แƒก แƒจแƒ”แƒคแƒแƒกแƒ”แƒ‘แƒแƒจแƒ˜

    A statistical analysis of data on the number of days with hail in the warm half of the year (from April to October) in 10 settlements of Kvemo Kartli (Georgia) - Bolnisi, Dmanisi, Gardabani, Manglisi, Marneuli, Rustavi, Sadakhlo, Shulaveri, Tetri Tskaro, Tsalka - is presented. The observation period is from 30 (Sadakhlo) to 93 (Bolnisi) years. In addition, an analysis of data on damaged areas of agricultural crops in 34 locations of the specified region in 1982, 1985-1989 is provided (total 56 cases with hail). In particular, the following results were obtained. The maximum number of days with hail in the warm half-year is observed in Manglisi (16), the minimum - in Rustavi and Sadakhlo (2 each). The maximum average number of days with hail is observed in Manglisi (4.6), the minimum - in Sadakhlo (0.2). The maximum total area of agricultural crops damaged by hail was noted in Asureti (8.15 kmยฒ), the minimum in Tbisi (0.2 kmยฒ). The maximum area of agricultural crops damaged by hail by 100% was noted in Sadakhlo (6.18 kmยฒ), the minimum - in Tbisi (0.07 kmยฒ). In the whole region, for one incident with hail, the total area of damage to agricultural crops was 1.64 kmยฒ, and for 100% - 0.95 kmยฒ. The results of this work will be used to construct a visual map of the distribution of hail cases and hail damage of agricultural on the territory of Kvemo Kartli

Kura and its tributaries, which caused enormous damage and casualties. It is noted that the increase in damage is caused by an increase in the frequency of high rains, strong anthropogenic changes in the underlying surface, as well as a decrease in the infiltration capacity of the soil and the water permeability of river channels. Under the conditions of global warming, the expected increase in the intensity of precipitation will cause more frequent catastrophic floods. In order to ensure safety and reduce losses, appropriate preventive measures should be taken

The temporal variability of the measured values of the number of days with hail, as well as the moving averages of the number of hail days for 3, 5, 7, 9, and 11 years, has been studied. It is found that the time course of all the indicated series of observations is negative and is described by the linear regression equation. At the same time, the level of linear correlation between years and the measured number of days with hail, as well as moving averages of the number of hail days, increases as the averaging range increases up to 11 years (from -0.22 to -0.63, respectively)
