What's up with the tie, and don't you think it might be more than coincidental that this is occurring around the tie?
That was my first question...seen many dead or dying trees girdled because the installer forgot to take off the top of burlap or wire basket/ didn't come back and loosen the straps...sad.
It looks like this tree had low tie wraps and wind or whatever might have cracked the trunk
