The USGS isn't giving a fault plane solution, and I don't think there is much coverage, but this is one of those random events that happens in relatively stable geology. I did get a streetview.
Very mountainous, so you'd expect a lot of internal stress adjustments. The felt area shows a uniform pattern of very low ground motions.
This is what you'd expect for something that is more than 20 km deep. I'm doubting they'll see another one soon.
Update: Normal (tension), the least of ground motions.
