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...
