“Borovoye” (BORK) seismic station of IRIS/IDA network

A new seismic station BORK started its operation on August 22, 2019.

From 1994 near this station there was BRVK station. The information on BRVK station is available at http://ds.iris.edu/mda/II/BRVK/?starttime=1994-09-01T00:00:00&endtime=2019-08-21T23:59:59.

BORK seismic station of the global IRIS/IDA stations network is located at “Byurabay” settlement of Byurabay region, Akmola area. “Borovoye” seismic station is located within Borovoye intrusive massif of alaskitic granites of late Silurian – early Devon period breaking formations of Archean, upper Riphean and Cambrian periods.

Seismic sensors of the station – STS-5, STS-6 are installed in the wells located in the equipment vaults. The wells depth is 40 meters for STS-6, and 10 meters for STS-5. The accelerometer Episensor ES-T is rigidly tightened to the concrete floor of the equipment vault. The recording instruments - 26-bit ADC (for seismometers) and 24-bit ADC for the accelerometer Quanterra Q330HR are installed near the sensors. Sample rate: 40 samples/sec/channel for seismic channels, and 100 samples/sec/channel for the accelerometer. The accelerometer operates in gated mode. Time scaling is GPS. All equipment is installed in the equipment vault. Internet connection is through the DSL modems. For this purpose, there is a cable laid between the equipment vault and administrative building (~650 m).
