KARAGANDA (KARABASS) EARTHQUAKE onJune 21, 2014, KP=11.7, MS=4.0, I0р=5 (Central Kazakhstan)

Abstract

The work shows the results of macroseismic analysis of the earthquake with mb=5.2 occurred near Karaganda on June 21, 2014 and recorded by seismic stations of the Institute of Geophysical Research ME RK. Basing on the data of macroseismic examination that included acquisition and analysis of information on the dam-aged houses and industrial buildings, the shaking intensity on MSK-64 scale was estimated for 34 settlements on the territory of ≈100 km radius around the earthquake epicenter. For the Karaganda earthquake localized in the area that was previously considered aseismic the basic parameters is studied, the focal mechanism is constructed, and the isoseismal map is compiled. Basing on the analysis of seismic records, focal mechanism and geological and tectonic features of the region, it was concluded that the natural-induced nature of the earthquake is most probable.
