Hi,

I work for a small R & D firm in Germantown, MD. We are investigating methods to distinguish man-made events such as chemical or low-yield nuclear explosions from natural events such earthquakes.
I know how to request data resulting from earthquakes but have not idea how to get waveform data resulting from man-made events. Does IRIS hold data for man-made events? If yes, may I get some guidance as how to get them?

Any response is appreciated.

Thank you.

    Hi Hua-mei Chen,

    Unfortunately we don’t have a single service that is specifically designed for serving man-made event data. We do have a few areas that may be of interest to you however:

    In our PH5 archive we have a collection of active source experiments that include data from active source (explosive, airgun, vibrator truck, etc) events. The PH5 web services can be used for accessing this data:

    http://service.iris.edu/ph5ws/

    Additionally there are a number of assembled data sets. Some of these may include active source experiment data, but you’ll have to manually look through the list:

    http://ds.iris.edu/mda#adata

    Lastly IRIS hosts an Exotic Seismic Events Catalog (ESEC https://ds.iris.edu/ds/products/esec/) that contains information about non-earthquake seismic sources. These are mostly naturally occurring events, such as landslides, avalanches, floods, etc.., but you may find it useful.

    Thanks,

    Nick

      Nick,
      Thank you very much for your help and guidance. I will look into the links you provided.
      If you don't mind, may I have another question for you?
      From the events returned from Wilber 3 service, is there a way to figure out if the source is an earthquake or explosion or some other natural or man-made event?
      I will need this type of ground truth to test our approaches. 
      Thank you very much.
      Regards,
      Hua-meio

        Hi Hua-mei,

        I consulted a colleague of mine who showed me to a better source of man-made events.

        He said that you should use the IASPEI Ground Truth events database.

        http://www.isc.ac.uk/gtevents/

        As the page indicates - "GT1 and GT2 events are typically explosions, mine blasts or rock bursts either associated to explosion phenomenology located upon overhead imagery with seismically determined origin times, or precisely located by in-mine seismic networks.”

        These reference events would be more appropriate for your use case.
