Known Performance Issues:
ASCN – The T360-BH sensor is showing high frequency noise due to conditions external to the sensor.
BORK – STS-6 channels showing long period pulses with a period of approximately 53m 41s.
CMLA – The horizontal channels from the STS-6 are showing long period noise. The “2” components from the STS-5 are showing occasional offsets.
DGAR – The response of the STS1-N is anomalous. The STS-1 horizontals are showing intermittent sensitivity changes, at times reducing to roughly 0.5 of nominal.
ERM – The M2166 sensor is showing long period noise on the vertical channels.
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.
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. Data quality for the LN200/EN200 channels from the Episensor is poor.
NRIL – EME wishes to delay upgrade until the station can be relocated.
OBN – The CMG-3T channels are noisy since March 2020.
RAYN – All channels from the T360 are pulsing and show occasional long period noise.
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. The station is currently down due to power issues.
SACV – The T360BH channels are noisy.
WRAB – The T240 horizontal channels are noisy.
