Abstract
The capability to record events of different magnitude at various epicentral distances (magnitude sensitivity of the station) was studied basing on representative statistical material ontained by the results of Karatayu seismic array operation for more than 10 years period. The dependence of magnitude sensitivity on azimuth of seismic waves arrival was studied. It is shown that depending on the direction, the station has different capabilities in recoding of small earthquakes at the same distance. The examples of small events recorded by Karatayu station are shown by a series of two explosions of shells at military warehouses in the south Kazakhstan in 2019 and 2021.
