There is now a summary at the link:
https://earthquake.usgs.gov/earthquakes/...#executive
Similar to what I wrote except they say the right-lateral quake is on the plate boundary, implying no subduction. Not sure of they are correct; there seems to be a trench. I suppose a slab may be imaged or not imaged and it is known if there is subduction, so I could be wrong and USGS could be correct. But remember 2004 Indonesia: the northern part of that rupture is highly oblique plate motion yet it still had a subduction quake. I recall that most seismologists thought it could not have a Great subduction quake in the north.
