“Ortayu” seismic station (OTUK)

 


OTUK seismic station was put into operation under CAREMON Project; it is located on the skirts of Ortayu settlement, Shetskiy region, Karaganda area. The equipment vault in which seismic sensors and recording equipment are installed is constructed on sloping ledge of bedrock exposure of dense potassic-feldspathic granites of Kyzylrayskiy complex αγP2 – T1kz and represents a bunker of 3 m depth.

Seismic sensors of the station: seismometer CMG-3ESPC and accelerometer CMG-5TC are installed on a pedestal in the equipment vault of 3 m depth. Recording instruments: 24-bit ADC CMG-DM24S6 is installed near the sensors. Sample rate: 100 samples/sec/channel for all channels. Seismic data are digitized according to GPS. Seismic data are processed by a field computer CMG-EAM and are transferred to the satellite modem via local network. At the same time data are accumulated in the hard disk of this computer.

Response and phase characteristics of the installed seismometers are here.
