Note: expanding the imaging region to the SW may reveal even further/later, weak but coherent, rupture.

Using the plentiful aftershocks as empirical corrections is probably helpful. If you can crack the triplication complication, I'll guess it'll be an excellent paper!

To all young seismologists with more time and (higher-frequency) energy: F-net/Hi-net is 15-30* away along strike and China maybe 15-40?*. This rupture is begging to be carefully analyzed at multiple frequencies.

More careful analyses might reveal something interesting (these are automated), but along strike BPs can be funny so it might be nothing. Often there are lots of constructive interference artifacts esp in the direction of rupture, but these BPs are among the cleanest smoothest that I've ever seen

AU are my favorite, the separation up dip and down dip at 148s is something I've never seen. I'm hesitant to immediately dismiss it as artifact since it "moves" so slowly and appears stable.

These results are close to the current USGS FFM, but put the late large coherent energy release maybe 60ish km further away along strike. What makes these so "nice" is that it's rare for so much agreement between different azimuths and between the regionals and lower frequency GSN results.

And here's a pretty movie of surface waves going across North America:
