I always wonder when I see an earthquake reported at 5.0km or 10.0km depth if that's a signature of some DUMB house cleaning. I suspect the CIA built several of these and with Gina's recent unplanned vacation it's a little more interesting to see a pop of round numbers. I think a bunker buster would register around a 3.0 - 3.5 mag depending on factors, I suppose, but I think we are in the ballpark with regard to magnitude.
So, here's the short list from the last week: USGS Earthquake Monitor
M 3.5 - 55km ESE of St. Cruz, VI, 10.0km depth <= St. Cruz is right next to Epstein's Little St. James
M 2.8 - 5km W of Andover, KS, 5,0km depth
M 3.2 - 16 km WSW of Stanley, Idaho, 10.0km depth
M 2.5 - 22 km WNW of Stanley, Idaho, 9.4km depth (close-by location, so included)
M 3.1 - 187 km W of Bandon, Oregon, depth 10.0km
M 3.2 - 12 km NNW of Bowdle, South Dakota, 5.0 km depth
Total speculation anons, but an interesting possibility given recent events.

Approximately, what kind of scale of damage would a 15.0 EQ do? Understand it depends on location and depth, etc., but am looking for a general account. They say such a level is impossible but was curious what someone that follows this topic closely thought. Thank you!

10km is awfully deep to be cleaning out DUMB.

Compared to any other depth, 6.2 miles (10 km) appears way more frequently on the earthquake app I use. Assuming the earthquakes are occurring randomly, I wouldn't expect to find too many at similar or same depth. I can't say definitely it means DUMBs but there is some reason they seem to cluster at that depth.

You have a good point anon, and doing some looking around I find that 10.0 is the 'fixed depth' value for when the data is poor, so that could be one explanation for the spike in 10.0 values. In prior observations I've seen several 5km clustered so that's really the pattern I'm referring to. Thanks for the comment, I learned more today!
