Thread: Error with 1997 data from XA Network, Anatomy of an Archean Craton, South Africa

To whom it may concern,

I am having trouble obtaining BHZ data from network code XA,
description, Anatomy of an Archean Craton, South Africa. This network
ran from 1997 to 1999. I am having trouble with some of the events
from 1997. When I run rdseed, I encounter a segmentation fault error.
I tried viewing some of the 1997 events as seismograms on JWEED, and
received this error for multiple events.

Error detected decoding data to ints.
Error:IDL:iris.edu/Fissures/FissuresException:1.0 Codec Exception:

I didn't have any trouble using rdseed with XA network data from
1998-1999. I suspect some of the 1997 event data may be corrupt.

  • Thank you for letting us know, Kameron. We'll take a look at the XA dataset and see if there is an issue with the data encoding markup. The waveform data comes with some kind of encoding, and we mark this in the records with a number to indicate the type (Steim2, CDSN, etc.). A value of 0 used to map to nothing, but SEED 2.4 indicates that it can mean ASCII text. Whether or not this is true remains to be seen.

    • Kameron-

      If you have time, can you provide an event date and time that you saw the error? This will help us to focus on that specific area for troubleshooting.

      Thanks!
