[Predator 2] What happened to the apartment building and all of its inhabitants after the Predator spaceship took off at the end of the movie?

It appears the Predator spaceship was underneath the apartment building and after the spaceship took off, we see Lt. Harrigan in a desolate area with burning fires in Los Angeles with no apartment building in sight.

While it's true that the spaceship was below the apartment building, the actual structure it was in was an abandoned tunnel of some kind. To make its escape, it needed to travel some distance down the tunnel; evidently, that distance was great enough that the apartment building was no longer readily visible at the point where Danny Glover emerged -- at least from the angles we could see.
