Mount Etna: Why scientist fears 1000 degrees volcanic FIREBOMBS pose threat 

The last event, in December 2018, was a lateral eruption that spewed volcanic ash into the air and triggered a 4.8 magnitude earthquake.

However, volcanologist Boris Behncke, from the National Institute of Geophysics and Volcanology, has warned of another threat Etna poses.

Mr Behncke detailed during Amazon Prime’s “Volcano Stories” series, how 1000 degree “bombs” of molten rock are constantly shot up into the sky.

He said in 2018: “You can see the snow here has melted because it was so hot – that’s caused by a bomb – it came here and melted a hole in the snow.
