Operations Status

Known Performance Issues:

ABPO - There are problems yet to be determined preventing remote calibration of the STS-2 seismometer.

ASCN – Streams from the KS-54000-Z are non-seismic.

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

JTS - The STS-2.5 is showing small amplitude oscillations on the LHZ-10 channel.

MBAR - The horizontal channels from the KS54000 are noisy.

NIL – KS-54000 Z’s response is anomalous following flooding in spring 2013. The station is currently experiencing intermittent power outages.

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 STS1-N is very noisy.

PALK - All channels from the Episensor strong motion sensor are non-seismic starting day 2017,321.  There is a problem with the KS-54000 seismometer preventing it from responding to calibration commands.

PFO – The STS1-N is very noisy.

TLY - The station is down since 2015,360 due to power problems.

WRAB - There is excessive background noise on the vertical channels from the KS54000 seismometer since day 2017,329-15:33.
