That is definately a hazard tree and will likely split in a wind storm. It should be removed. http://www.na.fs.fed.us/spfo/pubs/howtos/ht_haz/ht_haz.htm Newt
Actually, there is a bark ridge so it may not split anytime soon, if ever, especially if in a location where heavy, wet snow does not accumulate on trees. If valued enough it might also be possible to hire an arborist to cable it together, or find out how to do it yourself.
With no disrespect to Ron, cabling and bracing are best done on valuable trees and are usually temporary at best. Wind and rain can also cause a heavy load on a tree.

If in doubt a certified arborist should be consulted. Newt
Michael, are you referring to the tree in the picture by POPO? If so, I would say "yes" if it splits and falls on someone. It's next to a sidewalk. Imagine a baby in a stroller and it falling on top. Not a nice scene. Newt
Hi Newt, Maybe one of us is misjudging the size - it looks to me like the whole thing is about 2m tall, with a trunk maybe 5cm diameter.
Michael, sorry I didn't answer sooner but I don't think I received a notice on your response this time. I'm thinking the tree isn't much larger then that either, but it will grow eventually. As the limbs get larger and heavier the risk gets greater too. Even if it were to be kept at the height you suggest, there would still be a risk of failure. The split goes all the way to the rootflare. Newt
The diameter of the tree is about 6-7cm now, they are planted just next to the Alhambra city Hall and Police Dept, I believe their gardener will monitor these tree's growing.
