This rise was hot gas being released to the surface. If the gas is about 800° C hot, it heats the rocks at the vent to incandescence and
you can actually see this on the cams at night. Ash and steam are also ejected. I could.'t see the incandescence last night though. It looks like
Popo is doing the same thing which is worrying. I haven't studied her but incandescence in Etna is usually a sign of near eruption.
