ANALYTICAL REVIEW OF GLOBAL AND DOMESTIC SOURCES ON THE STUDY OF SEISMIC PROCESSES IN GLACIERS UNDER THE INFLUENCE OF CLIMATE CHANGE

Global climate change affects almost all spheres of human activity and the world ecosystem as a whole. Temperature rise, in particular, leads to accelerated melting of glaciers, which in turn leads to changes in the flow of glacier-fed rivers. This phenomenon inevitably affects the livelihood of settlements that use water from these rivers. Seismic and infrasound stations of the NNC monitoring network have been recording ground and air vibrations for many years. The accumulated database of instrumental observations contains information on climate changes in previous decades, such as the frequency and spatial distribution of glacial earthquakes. In this regard, it is proposed to analyze the changes in the glacier destruction regime based on the study of seismic and infrasound data obtained over the last two decades by the Kazakhstan monitoring network and to study the relationship of the found patterns with global climate change. This paper describes modern ideas about climate influence on mountain glaciers, general information about changes in the size and condition of glaciers in Kazakhstan. The possibility of using cryoseismology as a new tool for studying the dynamics of glacier changes is considered. The paper concludes with the results of the study of glacier dynamics using seismic methods in the Tien-Shan area according to the literature data.
