Italy’s Mount Etna, the highest and most active volcano in Europe, erupted on Monday, December 24, sending an enormous column of ash into the sky and causing closure of Catania airport on the eastern coast of Sicily.

A chain of about 130 earth tremors rocked the volcano since around 0800 GMT, Italy’s National Institute for Geophysics and Volcanology revealed, with the strongest posting magnitude of 4.0.

So far, there have been no reports of injuries.

The 3,330-metre high volcano can burst into action several times per year, spewing lava and ash high over the island in the Mediterranean. The last major eruption happened in 1992.
