In 1994, a contemporary digital network of seismic and infrasound stations was established in Kazakhstan. Successfully operating network is located throughout the perimeter of the Republic territory. At the present time, KNDC receives in real time and processes data from 4 infrasound arrays: Aktyubinsk IS31 (in the west of Kazakhstan), Kurchatov KURIS (in the east of Kazakhstan on the territory of the Semipalatinsk Test Site), Makanchi (in the east of Kazakhstan), and Zalesovo IS46 (Russian Federation). Using data of these stations, infrasound events are detected automatically, and an infrasound events bulletin is created on a regular basis. At the present time, the issue of appropriate parameters selection for events location and identification of infrasound sources is topical. In this regard, it was decided to create a database of infrasound events basing on the infrasound signals from powerful quarry blasts with known parameters.
The created database can be used for solving different monitoring tasks, such as calibration of infrasound stations, discrimination of infrasound signal source, precision of explosion parameters, determination of explosion yield and other.
