H. Abstract: To assess the intensity of strong historical earthquakes on the territory of Armenia, a special macroseismic scale was compiled based on statistical data on the damage to the buildings of Armenian churches by the devastating 1988 Spitak earthquake. It is important that the stored data covers a long period of time (about 2000 years) without big breaks. The absence of a macro-seismic scale made it impossible to accurately determine the severity of these earthquakes. Therefore, this information was interpreted differently by different seismologists, and the strength of earthquakes was largely underestimated. A new preliminary special scale was created based on the damage analysis of church buildings located in the 7-10 intensity zone of the 1988 Spitak earthquake. It was necessary to improve this scale with other, well-studied, similar studies of earthquakes. We chose the 1926 Leninakan earthquake having studied in detail the technical condition of the church buildings damaged by this earthquake, the injuries received local factors affecting the seismic intensity (soils, relief, groundwater level, etc.), types of church buildings and written sources about their damage, and summarizing them, we tried to improve a special macroseismic scale.

S. Abstract: The results of the study of the consequences of the 1988 earthquake in Spitak showed that many illegal modifications were carried out by the residents in the apartment buildings, which led to the reduction of the seismic resistance of the buildings. For example, the reason for the collapse of at least 10% of stone apartment buildings in Gyumri was also one of those illegalities. This issue remains relevant to this day, so these illegalities must be prevented, and those committed in the past must be eliminated. In this work, we tried to identify the allowed illegal modifications, dividing them into groups according to the danger of affecting the seismic resistance of the building.

Abstract: The main goal of this research was the analysis of dynamic changes in dam foundation displacement according to the periodic variation in water level in the lake around the Enguri Arch Dam. We used a database, for the information collected from 1974 to 2021. In this work, we have tested and analyzed the dynamical changes by modern several nonlinear methods. We choose one of the most effective methods Multifractal Detrended Fluctuation Analysis (MF-DFA). From the results of our research, we can see that dynamic changes in dam foundation displacement are connected with the process of dam behavior. One of the main facts is that water level change in the reservoir behind the Enguri high dam also affects this process.
