Hi,
I do some rudimentary moment tensor "beachball" work with my high school freshmen, and I was wondering if there are alternative sources for moment tensor solutions. I'm waiting to see if the N. Korea nuke test, which showed up on the world seismicity map, will get a moment tensor posted. A solid color beachball would be interesting to observe, especially because I show it to them as an example of a non-tectonic seismic source. Also, do all the earthquakes in the USGS lists eventually get solutions posted (NEIC, Harvard)? Thanks.

    Craig,

    There will probably be special studies of the seismic data from the
    test, but since it was so small, I doubt anything will be posted on
    the USGS site. I'm not sure that there were enough stations
    recording the event to do a proper moment tensor analysis.
