Database includes a parametric catalogs of five types of natural hazard events (landslide, debris flow, flash flood, windstorm, and hailstorm) causing significant economic loss and casualties in Georgia over the last decades and centuries, respectively. The compilation of catalogs of these events is innovative as the entire country is covered, and it is timely and may be used by civil protection, risk managers and other stakeholders in order to provide information for natural hazard and risk management as well as decision-making with respect to effective and efficient mitigation measures. The data included in the database was collected based on minimum requirements of data quality. Data quality included information on the order of magnitude for each hazard type and the corresponding recurrence periods, a magnitude classification and harmonization of the corresponding data was carried out. For each natural hazard type and event, the most reliable values of the main parameters were collected, determined from the set of available information. These included date of occurrence (year, month, day), time of occurrence (hour), location of occurrence (geographical coordinates), magnitude and intensity (see VarazanaSvili et al., 2012; 2022) where appropriate, affected area, and associated loss (number of fatalities; losses in terms of economic values) In the Catalog of Landslides (catalog authors - G. Gaprindashvili, O. Varazanashvili) were collected for the period from 1900 to 2022, 1636 events. The magnitude of landslides (MLL) was taken as the logarithm of its volume (in m3), with a resulting range between 2.00 and 8.70. In the Catalog of Debris flows (catalog authors - G. Gaprindashvili, O. Varazanashvili) were collected for the period from 1776 and 2022, 880 events. Debris flow magnitudes (MDF) were taken as the logarithm of the maximum volume (in m3) of debris material discharged during a single event, with a resulting range between 2.30 and 7.40. In the Catalog of Flash floods (catalog authors - Ts. Basilashvili, O. Varazanashvili) were collected for the period from 735 and 2022, 1098 events. Flash flood magnitudes (MFF) were taken as the logarithm of the water peak discharge (in m3 /sec), with a resulting range between 1.06 and 3.78. In the Catalog of Windstorms (catalog authors - E. Elizbarashvili, O. Varazanashvili) were collected for the period from 1946 and 2022, 1563 events. Windstorm magnitudes (MWS) were taken as wind speed (in m/s) divided by ten, with a resulting range between 3.00 and 5.60. In the Catalog of Hailstorms (catalog authors - A. Amiranashvili, O. Varazanashvili) were collected for the period from 1891 and 2022, 2186 events. Hailstorm magnitudes (MHS) were taken as the hail grain size (in mm) divided by ten, with a resulting range between 0.10 and 11.00.
