Kazakhstan:

Abstract

In 2013, seismic monitoring in Kazakhstan was conducted by two organizations: the Seismological Experience-Methodical expedition of the Ministry of Education and Science of the Republic of Kazakhstan (SEME), and the Institute of Geophysical Research of the Ministry of Energy of the Republic of Kazakhstan (IGR). The station network consists of three-component stations and seismic arrays. The work presents detailed information on seismic observation networks. The catalogue of seismic events of Kazakhstan is made by da-ta of above mentioned Organizations. It includes 1036 earthquakes with energy class КР=6.6–14.7. The catalog contains several additional sheets with Attachments: Microseismic data on felt earthquakes, parameters of focal mechanisms of 55 earthquakes, information on coordinates of 29 urban areas with felt shakes, parameters of 1123 aftershocks, and two forshocks of Saryzhas (Narynkol) earthquake in the range of energy classes КР=4.5–11.8. Two maps of earthquake epicenters are shown in the paper: for the whole Kazakhstan territory with КР≥8.6 and for Northern Tien Shan territory with КР≥6.6. The largest earthquake of the year was the Saryzhas earthquake that occurred in Northern Tien Shan on January 28, MS=6.0, КР=14.7. The earthquake was felt on the territory of Kazakhstan and China and was followed by numerous aftershocks. For the first day, only its number exceeded 500. It was noted that the total released seismic energy in 2013 exceeded significantly the same parameter of 2012.
