Mount Etna in Sicily had a pretty spectacular short eruption a couple of days ago. In addition to the fairly routine (but beautiful and fascinating) lava fountains, Etna also launched a few small pyroclastic flows, which is not something it's noted for. They may have occurred partly due to interaction with newfallen snow. Whatever the cause, it was quite a display.
Also it's high-definition; looks great at full screen.
