Makanchi (MKIAR)

Makanchiinfrasound station (MKIAR)

Makanchi infrasound array (MKIAR) is located at Urdzhar region of the East Kazakhstan area, 25 km eastward of Makanchi settlement; the array elements are inside Makanchi seismic array exceeding it by aperture. The station was constructed by the IGR together with AFTAC in 2016; the KNDC archive has the station’s data from August 2016.

The infrasound sensors, microbarometers Chaparral Physics Model 25 and digitizers AIM24S, are installed in the bunkers. In total, there are nine such equipment vaults. As for the configuration, the central station is surrounded by 4 stations, and 5 other stations are installed along a large circle. The wind interference suppression devices are connected to the microbarometers inputs. The sample rate is 40 samples/sec/channel. Timing scale is GPS. Infrasound data are transmitted to the Center Processing Facility via radio modems – a repeater is used. After that the information is transmitted to the CAPSSI via the satellite channel. And from Almaty the data of Makanchi infrasound array are transmitted to the National Data Centre of the USA (USNDC) in Florida (USA).
