I think it's worth pointing out that not all sandboxes are location-based. One can fill a sandbox with location-agnostic "plots" (each consisting of a series of scripted/improvised/player-initiated events) as easily as one can fill it with locations with attached "situations".
From my standpoint the salient feature of a sandbox is that the choice of what setting elements to engage with belongs to the players. Those setting elements can be location-based or event-based or some mix of the two.
To be clear, when I'm talking about "event-based (or plot-based) games," I'm referring to storylines like a group trying to play HotDQ and RoT or a homebrew in that fashion. When I'm talking about "location-based games," there is no storyline, just places to poke around and adventure. For the purposes of this discussion, I think that's a clear delineation that is necessary to understand each other's point of view. I see both sides because I run games with both approaches. Of course plot-based games have to take place at a location of some kind and of course locations may have some kind of situation unfolding within them. We can take that as a given in order to focus on the clear differences between the aforementioned approaches.
