“Kurchatov” seismic station (KURK) of IRIS/IDA network

A new seismic station KURK has been run on September 1, 2019. From 1995 almost at the same place there was KURK station operating with other instruments. The information on the old station is available at http://ds.iris.edu/mda/II/KURK/?starttime=1995-03-26T00:00:00&endtime=2599-12-31T23:59:59.

  KURK seismic station of the global IRIS/IDA stations network is located near Kurchatov town at the East-Kazakhstan area.The equipment vault is in alluvial-proluvial sand and rubbly-pebble sediments of Quaternary period.

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. The recording equipment is installed in the equipment vault, the processing instruments – in the building.
