I've seen this movie. It doesn't go well for people.
Looks like it is heading toward Addis Ababa.
Edit: Yes. I found this photo of the person who located it.
Which element leaves a green trace in its wake while it burns? It's not iron, is it?

It could be copper, barium, and/or boron, as all of these burn green. Copper tends to be more blue green, with copper chloride burning an emerald green. Barium is often a pale green and a boron flame will have a green hue as well.
