Last year, 80 eruptions occurred at 75 volcanoes, with 32 new eruptions recorded. This is pretty much par for the course, interestingly, and looking at the year-on-year figures for the past few decades, there is no indication that volcanic activity is increasing.
MOUNT ETNA, ITALY
Something’s always happening at Sicily’s Mount Etna. Etna demonstrates two different types of activity: ash explosions and over-spilling lava flows from one or more of the four summit craters, and larger volume lava flows lower down on the flanks. During 2021, the action was all at the summit, where spectacular lava fountains up to 1km high often lit up the sky over eastern Sicily. Periodically, more violent blasts launched huge columns of gas and debris high into the stratosphere, deluging surrounding communities in ash, and closing Catania airport at the foot of the volcano on a number of occasions.
