Operations Status

Known Performance Issues:

ASCN –  The T360-BH sensor is showing high frequency noise due to conditions external to the sensor.

BORK - Data quality for all channels from the STS-6 is poor as of day 2020,162-04:27.

CMLA - The horizontal channels from the STS-6 are showing long period noise.

DGAR – The response of the STS1-N is anomalous. 

ERM - The M2166 sensor is showing long period noise on the vertical channels.

JTS - All channels from the STS-2.5 are showing long period oscillations.

KURK - The STS-6 horizontal channels are noisy.

KWJN - The infrasound and weather station channels are not being emitted due to issues with the QEP.

MSEY - Data quality for the "2" component channels from the KS54000 is poor. 

NIL – KS-54000 Z’s response is anomalous following flooding in spring 2013.  KS-54000 channels are nonseismic (bit noise) after faulty Q330 replaced.

NNA - The STS-2 is showing excessive long period noise since August 2018. 

NRIL – EME wishes to delay upgrade until the station can be relocated.

OBN - The CMG-3T vertical channels are noisy.

PALK - Data from the STS-6 is bit-noise since day 2021,350.

RPN - STS-1E channels are non-seismic following a large offset day 2019,163-18:46.  Data quality from the STS-1N is poor as of day 2020,187-05:51.  The STS-2.5 horizontal channels are noisy suspected to be caused by a water supply pump near the station.  The NOAA provided VSAT link is inoperable.

SACV - The T360BH channels are noisy.  Comms issues between the wellhead and recording room are causing data gaps since October 2021.

WRAB - The T240 horizontal channels are noisy.
