This is a current discussion topic in the Australian Arborist Network.
The general consensus is on the predictability of the trees failure, though
this is no surprise as trees are brutally managed across the City (plenty
of other examples like this one in the same park).
Australian arborists seldom get the support to sustainably manage trees.
Though is this not a global reality...

I agree with Jim about the hazards of surveying by photo, however I'll
make a suggestion based  on what I can see.

There is a root barrier in the form of a road.  The kerb closest to the
tree is lifting and the tree has a lean away from the road that appears to
be relatively recent.  The kerb lift could have been just the effect of
secondary growth of the roots.  However, the combination of lifting and
lean suggest the tree has started to fail when the Google StreetView images
were taken.
