Europe’s most active volcano erupted in spectacular fashion sending smoke and ash into the sky and forcing a nearby airport to close.
There were no reports of injuries or damage and authorities said nearby towns were not at immediate risk.
Despite this, they are monitoring the volcano in Sicily closely as it poses a significant threat in the event of more extreme activity – like the Plinian eruption of Mount Vesuvius in 79AD that buried Pompeii under a blanket of ash.
But it is not the only threat the Italian volcano possesses. Scientists previously discovered that it appears to be slowly sliding into the Mediterranean Sea at a steady rate, according to measurements.
The readings were taken in 2018 and it was the first time scientists were able to observe the movement of a volcano in its entirety, thanks to more than 100 GPS stations dotted around the sides of Mount Etna.
The slide was reported as slow but, according to the report, had “become unstoppable”.
Lead researcher Dr John Murray added in 2018: “Previous studies of long-extinct volcanoes found those sliding downslope in a similar way have resulted in catastrophic landslides later in their history.
“Constant movement could contribute to a major landslide along Etna’s coast, causing devastating tsunamis to the surrounding areas.”
Geophysicist Heidrun Kopp from the Geomar Helmholtz Centre for Ocean Research in Germany added that it was “quite possible that it could collapse catastrophically, which could trigger a tsunami in the entire Mediterranean”.
Experts previously thought the slide was due to a build-up of magma inside the volcano. To investigate the anomaly further, researchers set up a network of underwater transponders to continuously monitor seafloor displacement.
Researchers continue to probe Etna and monitor its activity closely.
