Etna has had one of the more memorable paroxysms. The tramor peaked at 190/106. The Paroxysm (eruptive phase) was short and very energetic.
At the end of it it looks like the ash-column failed rapidly as the heat driving it stoped. As the heated ash and suspended tephra fell down it took the same route as the lava flow. The lava flow had melted now and created a trail of clear white steam. It is rather easy to discern from the dark grey ash and tephra. Note what looks like orange glow in the material on a couple of the pics.
