(Finance) – Sea level rise projectionspublished in 2021 by the Intergovernmental Panel on Climate Change (IPCC) in AR6 Report, they would be underestimated along the coasts: this is what emerges from the research “Sea level rise projections up to 2150 in the northern Mediterranean coasts”published in the international journal Environmental Research Letters by a team of researchers from the National Institute of Geophysics and Volcanology (INGV) and the Radboud Radio Lab of the Department of Astrophysics of the University of Radboud (Holland).
Marco Anzidei, INGV researcher and co-author of the study explains that “subsidence, i.e. the slow downward movement of the soil due to natural or anthropogenic causes, has a crucial role in accelerating the rise of sea levels along the coasts, triggered by global warming since the 1880s”.
Antonio Vecchio, researcher at the Radboud Universiteit Nijmegen and first author of the study underlines that “Our analyzes show that, precisely because of subsidence, in some areas of the Mediterranean the sea level is increasing at an almost triple speed compared to stable areas”.
Meanwhile, a team of seismologists from the Etna Observatory of the National Institute of Geophysics and Volcanology (Ingv – Oe), observing the data coming from distant earthquakes (i.e. those which occurred more than 1000 km away from the observation site), obtained new information on the architecture of the upper mantle of southern Italy and, above all, on the possible correlations between faults already known at the level of the earth’s crust and deep structures affecting the upper mantle.
In the study “Seismic anisotropy to investigate lithospheric-scale tectonic structures and mantle dynamics in southern Italy” just published in the journal Scientific Reports of the Nature group, researchers have identified the existence of a discontinuity in the Earth’s mantle up to about 150-200 km deep , which would appear to be at the origin of an important system of faults that propagates across the whole of Sicily, from the area south of Etna, in a west-northwest direction, up to the northern coast.
