Still, it's an earthquake in the region. I wonder if the depth is reported as being too low, would an actual shallower depth allow for a quake that is further away? Or, if it's not really a quake but an underground explosion, could the seismic readings from the USGS confuse the depth and location, making it look like it was further away and deeper than it really was?

Ah.... now I know what my THIRD mistake was. (they always come in threes, for some reason)
Could/would you please share your link to that 2013 01 21 seismic data? The log would be useful, but I also want to look at actual 3-axis seismograph signals. I no longer have a travel time chart, but probably still can trace back to the event on data from more distant seismic stations...
Thanks in advance!

Here is the link for the correct day. The first one I listed was the wrong year (I goofed).
This second one shows a tremor, but it is apparently not centered where this ‘incident’ took place. (Thanks to Political Junkie Too)
Here ya go.

The signal we would be looking for in this case would be in the 1-3 range. (more dififcult to ID -- and much more difficult to see if signals for other events were arriving at the seismo station at the same time...)
That's why I want to look at the raw, 3-axis data/ seismograms...
My meteorology professor used it a few times. I had never heard it used before.
