First, this one is not from Etna; it shows the effect called a "skylight", where lava is flowing underneath the cooled surface rock. Would you walk on that platform?
There seem to be no end of excellent video images coming out of Etna, but my usual haunts don't have many good shots. At least, everything I've seen has been relatively uninteresting. This might be the best of the lot; a cable car hut that was just eaten. A real, live human structure taken out.
Another satellite image as the ash plume almost makes it across the Mediterranean. This makes me think of ancient people that didn't know of volcanoes across the seas, and what they would think if an incredible plume of smoke appeared on the horizon and eventually blew into their town.
