I have some photos of lights--standing in rows--on the side of Mt. Etna, moving about, they were there for about three hours in early November.

Since that time I have monitored six Etna sites, and never seen anything like the above, before nor since.

Lava simply doesn´t "stand up" in columns and move around like actors on a stage.

I honestly don´t know what it is that I photographed up there on the side of Etna.
