Mount Etna spews hot ash and lava after four years of dormancy

An eruption of Italy’s Mount Etna has disrupted flights at Catania airport in Sicily. The 3,330-metre high volcano is the tallest in Europe and is believed to have the longest documented history of eruptions among all volcanoes.

  1. This radiation-induced nucleation can lead to the pre-eruptive exsolution of H2O in the silica-rich magma. We note the possibility that the 1991 Mt. Pinatubo eruption was triggered by the same mechanism: an increase in cosmic-ray flux triggered by Typhoon Yunya, as a decrease in atmospheric pressure results in an increase in cosmic-ray flux. We also speculate that the snowball Earth event was triggered by successive large-scale volcanic eruptions triggered by increased cosmic-ray flux due to nearby supernova explosions."

  2. You need to update your info, as others have said, Etna erupts frequently and had an active period last year.
