Europe ALERT: Fears of huge earthquake or volcanic eruption after RISE in seismic activity

The latest quake came on Saturday in Greece when a 5.2 tremor took place in the Mediterranean country.
Italy was also subject to a huge earthquake earlier this year, when a 6.0 magnitude quake occurred in the middle of the country, taking the lives of 297 people.
More, smaller, earthquakes have been felt across Europe, and what is worrying experts even further is that the seismic activity could trigger volcanic eruptions.
An evacuation strategy is being put in place for Italy’s Mount Vesuvius which is due to blow, while small tremors around Iceland’s Katla volcano and Tenerife’s Teide have exacerbated fears the two are about to erupt.

Europe, particularly in the south, is extremely prone to earthquakes as two huge plates – the Eurasian, which covers Europe and most of Asia, and the African plate which goes all the way down to Antartica – are slowly colliding.
The fault line between these two plates is located in central Italy, which is what caused August’s deadly earthquake.
However, it’s not just Europe which is currently under threat from devastating earthquakes.
Mt Vesuvius also poses a risk to Italy
UTS Geotechnical and Earthquake Engineering senior lecturer Dr Behzad Fatahi warned that “no one is safe” around the globe from huge tremors.
Nonetheless, what is particularly concerning is that tremors where the Eurasian and African Plates meet are increasing as the historic fluctuation between the two is currently on the rise as tension increases beneath the surface.
Where the Eurasian and African Plates meet
Associate Professor of Earthquake Science in the School of Earth Sciences at the University of Melbourne, Mark Quigley, told news.com.au that the middle of Italy is currently undergoing “crustal extension”.
He added: “Eastern central Italy is moving to the NE relative to Rome. As a result, this region experiences normal faulting earthquakes as the land is torn apart.
“The fault systems are short and structurally complex, so the earthquakes are not overly large by global standards (almost always < magnitude 6.8 to 7).
“But because the earthquakes are shallow and structurally complex, and because many of the local towns and cities contain vulnerable buildings, strong shaking from these earthquakes has the potential to inflict major damage and loss of life in urban areas.”
What makes matters worse is beneath these plates there is a huge build-up of magma.
Dr Fatahi added: “The Eurasian Plate and African Plate both have a very big fault line where they meet somewhere under Italy.
“Below that plate you have got magma... if the fault opens there’s a chance magma will come up.”
