I am interested in an unusual grouping of earthquakes in the 1960's. However when I request station data I get the message:

"Error: There don't appear to be any stations active during this event."

Every earthquake I have clicked on between 1960 and 1969 gives this message. I notice that the IRIS browser does not show any quakes prior to 1970. Despite this I have been able to download data in this interval using Wilber 3 "Custom Query" mode.

My question is: Is this downloaded 1960s data suspect?

    Hi John,

    1970 is the earliest extent of our archived waveform data, but we have earthquake and station records going back further than this. This can lead to the dead-end that you encountered, where Wilber allows you to pick a pre-1970 event and the "suddenly" discovers that there isn't any data available.

    Wilber could put a limit on the age of earthquakes it shows -- this is what the IEB browser tool does, by the way -- but I can envision some conflict between this idea and some of the other features being planned for Wilber (mainly allowing federated requests across multiple data centers, whose available time ranges might be different). I will think about how we might handle this better.

    Cheers,
    Adam

      Thanks Adam

      That's fine, I am not that interested in waveform data. I presume the data
      I downloaded is okay itself. That is the important thing. I don't want to
      be criticised for using "bad data".

      Can you tell me how I should reference this data in a journal? The citation
      given for IRIS on the Web site is too verbose for most journals.

      Thank you for your prompt reply.

      Cheers

      John

        Hi John,

        Data citations should be for the network(s) that the data came from. This is an FDSN standard, and there is a tool for generating citations on the FDSN web site:
        http://www.fdsn.org/networks/citation/

        Cheers,
        Adam
