Two things odd: one is the obvious, that they're all at a depth of 10km. The standard answer from USGS is that this is a "default depth" -- which interestingly enough, they use even when other sources (eg the quakes in Iceland on the Iceland website) show varying depths. Odd mindset, that.
The second is more bothersome, because it shows that while the latitude is near-stationary, the quakes are shifting progressively in longitude. In other words, these are seismic events along a line, in proceeding in one direction, not just popping up in and around a central region more-or-less at random. To put it another way, it's like watching a crack opening up in slow motion.
