However, I would not think that one could say that it was not directly or indirectly related to the Chile Quake.
Subduction thrust quakes involve normally two plates...lol
In this case the south american and nazca.
That’s kind of what I thought, too, but the gist of what I got from that guy is that the Salta quake is just along a fault line that’s well on the South American plate. I don’t know the seismology, so I just present it as the “expert” says it.
