Abstract

In 2018–2019, the seismic monitoring in Kazakhstan was conducted by the Seismological Experience-Methodical Expedition of the Committee of Science of the Ministry of Education and Science of the Republic of Kazakhstan and the Republican State Enterprise «Institute of Geophysical Research of the Ministry of Energy of the Republic of Kazakhstan». The paper presents detailed information on seismic observation networks. The joint catalogue based on the data of two organizations was compiled. It includes 1050 earthquakes with energy class KR=6.6–12.8. The strongest earthquake within the considered territory occurred on February 1, 2019, KR=12.8, MPVA=5.6, Mw=5.0. Its epicenter was located on the territory of Xinjiang (China), near the Kazakhstan-Chinese border. The earthquake was felt in numerous settlements in Kazakhstan. On so-called “Northern Tien Shan” territory, the strongest earthquake occurred on March 26, 2018, KR=12.0, MPVA=5.5, the epicenter was near Kapchagay water basin on the territory of Iliy depression. For the period 2018–2019, on the territory of Kazakhstan there were induced and natural-induced earthquakes at the west, central, and east Kazakhstan. In whole, the period of 2018–2019 was characterized by moderate seismicity for the major part of the country’s territory.
