Thoughts on my impressions?
It seems the M7.5 #TurkeyEarthquake aftershock ruptured a different fault (or segment?) than the M7.8.
M7.8 -most likely a left-lateral event on a NE-SW fault (blue circle on image, from USGS)
M7.5 -95km to the N, most likely along an east-west left lateral fault
Now trying to place these over the known fault maps and it's messy!
