Station Details
OBN operational status:
2022.03.01
The station operator replaced the STS-1 seismometers with a Trillium360 seismometer day 2022,060.
2017.04.05
The station operator installed a second Q330HR digitizer and connected the CMG-3T to it.
2012.06.07
The station was upgraded to a Quanterra Q330HR system on day 2012,159. Sensors include an STS-1 and a CMG-3T seismometer.
2009.03.24
The vertical channels from the STS-1 seismometer were non-seismic from about day 2009,082-2010 to 2009,083-0828 due to a damaged circuit board in the DAS.
2008.12.20
The north-south BHN-10 channel from the CMG-3T seismometer was restored about day 2008,355.
2008.11.23
The north-south BHN-10 channel from the CMG-3T seismometer is non-seismic as of about day 2008,328 for reasons yet to be determined.
2008.05.30
The north-south BHN-10 channel from the CMG-3T seismometer was non-seismic from about day 2008,112-0940 to 2008,119-0852 for reasons yet to be determined.
2007.10.09
The East-West channels from the FBA-23 accelerometer are non-seismic as of about day 2007,282 for reasons yet to be determined.
2007.02.06
The North-South high gain short period channel was restored after the station operator recentered the masses for the CMG-3T seismometer.
2007.01.17
The North-South high gain short period channel (SHN) is nonseismic as of day 017-19:10 for reasons yet to be determined.
2005.12.26
The East-West high gain short period channel (SHE) is out as of day 360 (Dec.26) for reasons yet to be determined.
2005.11.25
An IDA engineer visited the station to upgrade the ISP, upgrade the hub computer systems, and train station operators on the configuration, installation, and operation of new systems for use at Russian IDA stations.
2004.07.11
The microbarometer data are back to normal.
2004.07.03
The microbarometer data are flatlined. Investigation is in progress.
