Earthquake in the Cosentino area, the Civil Protection: «This is why the 3.5 magnitude shock was clearly felt»

A shock of contained energy, but clearly felt: the reduced depth and the characteristics of the subsoil of the Crati valley contribute to explaining the effects of the magnitude 3.5 earthquake recorded at 8.38 on 10 November in Cerisano, in the Cosentino area. The earthquake occurred at approximately 8.5 kilometers depth. Added to this element is the presence of alluvial sediments from the Crati river, especially sands and clays, which can amplify seismic waves and make the shaking on the surface more intense. The perception of an earthquake, therefore, does not only depend on its magnitude: the depth and nature of the terrain crossed by the waves also contribute to determining its local effects. The episode is part of the seismic activity of Calabria, a region crossed by numerous active faults and historically marked by earthquakes of strong intensity. The Crati valley has also seen important events, including those of 1184, 1854 and 1870.
