SEISMOLOGICAL STUDIES OF GLACIAL PROCESSES IN THE HIGH-ALTITUDE TIEN SHAN

In recent years, cryoseismology has become an important area of research, providing new opportunities to study the dynamics of glaciers and their interaction with climate change. This interdisciplinary science, combining seismology and glaciology, opens up new perspectives for the analysis of processes in the cryosphere. In 2023, research of the Tien Shan glaciers using seismic and infrasound methods began at the National Nuclear Center of the Republic of Kazakhstan within the framework of the Targeted Financing Program (TFP) “Application of nuclear, seismic and infrasound methods for assessing climate change.” Three temporary seismic and infrasound stations have been installed in Kazakhstan, 70– 150 km from the large-scale glaciers of the high-altitude Tien Shan. Additionally, data from two stationary stations located at distances of 130 and 160 km from glaciers were used: the Shalkode station (130 km), which is part of the network of the National Scientific Center for Seismic Observations and Research of the Ministry of Emergency Situations of the Republic of Kazakhstan (NSCSOR MES RK), and the Podgornoye station (160 km), owned by the Institute of Geophysical Research The National Nuclear Center of the Republic of Kazakhstan (IGR NNC RK). These stations, located on rocky foundations, have demonstrated high efficiency in recording weak signals of glacial activity. Research confirms the importance of cryoseismological approaches for analyzing glacial processes and their relationship to climate change.
