Sicily: mount Etna eruption provides more quake

Several from the volcano Etna triggered earthquakes have shaken the earth in Parts of Sicily. In the night of Wednesday, residents were startled around the volcano, a violent earthquake with the strength of 4.8. “Fortunately there are no dead, only slightly injured,” said interior Minister Matteo Salvini. The news Agency Ansa, according to tens of people were injured by falling debris.

Since the beginning of the new activity of the volcano on 23. December were registered 60 earthquakes, which were greater than 2.5, such as the National Institute for Geophysics and volcano announced technology. Mount Etna is one of the most active volcanoes in the world. It always comes back to smaller and larger eruptions.

During a volcanic eruption earthquakes were frequent, said Professor Marco Bohnhoff, Director of the section geomechanics and rheology at the German research centre for Geosciences GFZ in Potsdam. “This is due to the fact that the volcano is continuously fed from below with Magma. If the pressure is too large, it breaks the Magma on their way.“ Volcano-tectonic earthquakes can be triggered when it comes in the underground, for example, to a discharge or a break-up.

earthquakes are an indicator, to be able to volcanic eruptions to predict, said Bohnhoff. These occur mostly in the 3 to 8 kilometers deep, because there magma chambers are. It comes down to Sicily to quake in greater depth, explain this with the Dive of the African under the European continental plate.
