Volcanic eruptions or lava flows you’ve heard of, but what about a volcano sliding into the sea? Scientists say that’s exactly what’s happening to Mount Etna, which The Open University described as the most active volcano in Europe. It’s the first time scientists have directly observed anything like it, and it could have disturbing consequences in the future. “Constant movement could contribute to a major landslide along Etna’s coast, causing devastating tsunamis to surrounding areas.” Mount Etna in Italy is headed towards the Mediterranean Sea. Researchers have observed parts of volcanoes move, but according to the BBC , these scientists think this is the first time anyone has directly observed basement sliding of a whole active volcano. They drew on 11 years of GPS measurements all over Etna to make the discovery.

Should we be worried? Etna might not slide into the sea in our lifetimes, so local residents needn’t be afraid, but “continued sliding for hundreds or thousands of years could cause it to become dangerously unstable,” Murray said. He told the BBC scientists should monitor the motion to see if it accelerates. Mount Etna’s movement may impact research today, however; Murray said it could interfere with signals that clue scientists into where magma is. It could be trickier to monitor the likelihood of an eruption. The Bulletin of Volcanology published the research online late last week; scientists from Université Clermont Auvergne in France and Nottingham Trent University in the United Kingdom contributed. + The Open University + Bulletin of Volcanology Via the BBC Images via Depositphotos and Wikimedia Commons
