S. Abstract: Destructive earthquakes can have a certain impact on the environment, conditioned by both the strength of the earthquake and local conditions, especially at the level of urbanization and seismic risk and the organization of disaster zone recovery. Based on the investigation data of the 1988 Spitak earthquake (intensity 9-10 points by EMS-98, M=7.0) these impacts can be divided into two groups based on the destruction of buildings and structures, activation of geological processes, and earthquake zone recovery period. The first group includes the collapse of buildings, activation of landslides, rock falls, soil liquefaction and subsidence’s, and activation of other geological processes that lead to changes in the environment. Larger scale earthquakes may have significant impact on the environment. For example, more than 50% of destruction of urban areas (especially buildings), major landslides (millions of tons of mass), collapse of reservoir dams resulting in floods, damages to lifelines (especially the main water supply and sewerage system), etc. The second group includes human activities during the earthquake recovery operations: selection of places to accumulate rubble, creation of temporary residential areas for the homeless and new settlements and districts, construction of new structures and infrastructure (transport, industrial, agricultural, etc.) especially in non-urban areas, destruction of green areas, cutting of trees, use of new areas for keeping domestic animals or setting up households, etc. Fri, 01 Jan 2021 00:00:00 GMT https://openlibrary.ge/handle/123456789/9585 2021-01-01T00:00:00Z https://openlibrary.ge/handle/123456789/9584 Title: Large Ancient Landslides of Armenia Formed During Strong Earthquakes, and Their Manifestation in the Relief Authors: Boynagryan, V. R. Abstract: The territory of the Republic of Armenia is located within the Mediterranean-transasian seismic belt and at the present stage of its development is characterized by high seismicity. This circumstance provokes the formation of landslides. At the same time, large landslides-blocks and landslides-flows up to 5-8 km long, up to 1-2 km wide and up to 100-170 m or more can form during strong earthquakes. On the slopes, such landslides associated with strong earthquakes of the past are distinguished by a characteristic relief, a relatively small amount of vertical displacement (100-200m, rarely up to 300m). At the same time, the amplitude of their horizontal movement in places reaches 0.5-1 km. This is due to the excessive horizontal acceleration obtained by a landslide during an earthquake. The report will consider examples of such landslides and their distinctive features.

Abstract: It is known that variations of water level represent itself an integrated response of aquifer to different periodic as well as non periodic influences, including earthquake related strain generation in the earth crust. The article deals about detected anomalies at the Oni borehole, during preparation of strong earthquake, with long epicentral distance. For this purpose, were developed the data of water level for Oni borehole. Were registered the hidrodeformation anomalies caused by the earthquake preparation processes. As a result, have been identified precursory anomalies and has been confirmed high sensitivity to the geodynamic processes.
