Ground Zero

I'm sure everyone has heard about the explosion at Glorietta 2. What on earth is Mike Enriquez thinking calling that site ground zero? That bomb in luk yuan is a dud. I don't think it could be linked to something as massive as a nuclear explosion.

Ground Zero is often defined as the surface directly above or below the point at which a nuclear explosion takes place. The term ground zero is also used for the site of the collapsed World Trade center twin towers.

Can't you people come up with something original instead?
