  1. Current Issues
    Station is still down. We have shipped equipment and CTBTO personnel are planning on upgrading to Q330 and restoring telemetry this year.
  2. 2014-09-25
    Spiking present on strong motion channels. Timing at the station was bad from Aug 2012 through April 2013 due to a bad GPS antenna. The 00 channels are currently not transmitting. Telemetry has failed.
  3. 2012-06-08
    Restored telemetry which was lost on 31 January 2012 due to a failed power supply.
