The previously unknown presence of magma in the southern part of the Apennine Range was discovered by specialists from the National Institute of Geophysics and Volcanology of Italy and the University of Perugia.
A new igneous source capable of throwing out gas can be the cause of earthquakes, including high-power, according to a study released Tuesday.
As the scientists explain, such conclusions were reached after a long and detailed study of the seismic phenomena in December 2013 – early 2014 in the area of Sannio Mateza on the border of the regions of Campania and Molise.
As project coordinator Francesca Di Luccio explained on Radio 1 on Tuesday, earthquakes in mountain areas are usually explained by the shear and fault of tectonic platforms.
“However, the greater depth of the source of the earthquake, lying at a depth of 10-25 km from the surface of the earth, in contrast to the less deep (10-15 km), suggested that such tremors are similar to phenomena in volcanic zones,” said the geophysicist.
At the same time, the Apennine zone is not volcanic, although scientists do not exclude the possibility that a volcano may appear in the geological time frame, which can be estimated in thousands of years.
Similar signals of magma rise in non-volcanic zones are recorded in the largest mountain system of Iran Zagros on the border with Iraq, as well as in the Andes.
According to scientists, this discovery allows us to better understand the evolution of the earth’s crust, and also better evaluate seismic risks.
Apennines are considered a young seismic zone. The whole history of Italy is marked by the strongest earthquakes, only in the twentieth century the elements claimed thousands of lives.
The last major earthquake occurred in August 2016 in the center of the peninsula, when about 300 people died. Behind the earthquake, which resulted in the destruction of the cities of Amatrice (Lazio region) and Arquata del Tronto (Marche region), in October new powerful earthquakes followed, leading to destruction, including historical monuments, but the victims were avoided.
Earthquakes occurred in 2009 in L’Aquila (Abruzzo) and in 2012 in the Emilia-Romagna region. As scientists insist, it is impossible to predict the tremors.
The only precautionary measure is the strengthening of the housing stock in accordance with the anti-seismic norms in order to avoid strong collapses.
