Operations Status

Known Performance Issues:

AAK - The STS-1N and STS-1E channels are noisy.

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

CMLA - Data quality for the vertical channels from the CMG-3T are poor since day 2016,238.

COCO – The KS54000 is not operational.

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

JTS – The STS1-Z and STS1-N are noisy.  The STS-1s were disconnected on day 2017,145 after equipment at the station was damaged due to lightning. Data from the STS-2 is still seismic and it is connected to a temporary digitizer installed until new equipment is shipped to the station.

KAPI – The KS-54000 horizontal elements are exhibiting tilt-like events. All channels from the KS-54000 are showing infrequent periods of offsets.

KDAK – KS-54000-N output is anomalously low since mid-2009 for reasons unknown. 

KIV - The North-South and vertical channels from the CMG-3T are noisy.

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 - Cannot calibrate or re-center STS-1s remotely due to e300 connection issues.

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

OBN - The STS1-N is very noisy.

PFO – The STS1-N is very noisy.

RAYN - The STS-2 N-S channels are showing step impulses since day 2016,243.

RPN - The STS1-E sensor is not calibrating correctly. The centering motors for the STS1-N and STS1-E sensors have failed.  

SACV – All channels from the KS54000 seismometer are non-seismic due to a faulty cable to the sensor.

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

UOSS - There is long period noise on all channels from the STS-2.5 seismometer.
