Known Performance Issues:
ASCN – The T360-BH sensor is showing high frequency noise due to conditions external to the sensor.
BORK – The STS-6 sensor failed on day 2024,135. Data is still being acquired from the STS-5 and Episensor.
CMLA – The horizontal channels from the STS-6 are showing long period noise.
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.
JTS – There are frequent pulses on the horizontal channels from the STS-6 and T240 sensors since Oct.2023.
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.
MBAR – All channels from the STS-6 are non-seismic since day 2024,102-14:57.
MSEY – All channels from the STS-6 are non-seismic since day 2023,365-13:24.
MSVF – Large offset on T120PH data day 2023,343-20:15, data quality deterioriated and BB210 channels non-seismic.
NIL – KS-54000 Z’s response is anomalous following flooding in spring 2013. KS-54000 channels are nonseismic (bit noise) after faulty Q330 replaced.
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. The station is down as of day 2024,135 due to ongoing uplink / communications issues between the wellhead and station computers.
SACV – The T360BH channels are noisy.
TLY – Station is down due to GPS issue 2024,217 (Aug4).
WRAB – The T240 horizontal channels are noisy.
