Mount Etna Eruption

Here's  the latest post from the website of Our Amazing Planet two days ago on the eruption of Italy's Mount Etna that took place on the morning of February 19, 2013. The dramatic scene was captured in a video by Klaus Dorschfeldt, a videographer and webmaster at Italy's National Institute of Geophysics and Volcanology. :




The article was written by Becky Oskin as
Mount Etna, one of the world's most active volcanoes, had emitted signs of an imminent paroxysm in recent weeks. On Jan. 22, lava and strong flashes in the volcano's New Southeast Crater were clearly visible from the Sicilian foothills; these often herald a new paroxysm: short, violent eruptive bursts.
Dorschfeldt said he knew Mount Etna's recent signals could precede new activity.  "[I've] followed the activity of Etna for many years, and with time you learn to know it as if it were your friend," he said in an email interview. "Following it constantly [you] learn to be a keen observer and a minor change can lead to something important," he told OurAmazingPlanet.
The tallest volcano in Europe, Mount Etna is almost constantly spewing gas or lava. Its Bocca Nuova crater also erupted earlier this year, from Jan. 10 to Jan. 20. In 2011, Etna's violent bursts were spotted from space.
I got it from Sigma Xi's Science Smart Brief this morning.
