A strong earthquake shook Sicily in 21:27 from this night. The epicenter was located off the coast of Scoglitti, in the province of Ragusa. The impact was magnitude 4.4 (as rectified by the INGV which initially indicated a magnitude of 4.6), but fortunately a 29.6 km depth. The moderate depth of the hypocenter has allowed the seismic tremors to dissipate going up through the subsoil, without serious effects in the epicentral zone. Fortunately, no damage has been reported, as confirmed by the Fire Brigade by specifying that operating rooms have received many calls for information only but no requests for help or reports of damage.
The depth of the shock, however, pushed the seismic waves a great distance: the earthquake felt like this also in malt and in Calabria southern.
So much fear in the population, especially a Victory, Abide, Gela, Ragusa, Modica, Syracuse and in the south / east of Sicily, with a resentment of up to 5th grade Mercalli. Fear also of Catania where the population was immediately frightened thinking of a resurgence of the volcanic activity of Etna, already particularly restless in recent days. The shock was also sensibly felt Palermo me Messina.
The President of the Region Nello musumeci is in contact with the prefect of Ragusa Filippina Cocuzza and with the head of the Sicilian Region – Regional Department of Civil Protection Except Kitchen for a constant update of the recognition of the consequences.

Earthquake in Sicily, unrelated to the activity of Etna
The earthquake that struck eastern Sicily at 9:27 p.m. is unrelated to the ongoing activity of Etna. “Absolutely notWas the response to the AGI of Stefano Branca, director of the Ingv of Catania, when asked if there is a relationship with the eruption. “From the point of view of magnitude – he added – it was not significant, as it was very deep (about 30 km). We are in the presence of the displacement of the African plate, which moves one millimeter a year. It is the dynamics of the earth’s crust.“.
Tonight’s earthquake was determined by the millimeter displacement of the African plate. “The outermost layer of the Earth called the lithosphere – explains Ingv’s website in a detailed column – is made up of several fragments called plates. These plates are in motion, so their edges are subject to sliding, traction or compression. When compression occurs, it can happen that one of the two plates slides under the other. This process is called subduction and generates earthquakes, sometimes very strong, both due to friction at the interface between the two plates and due to the deformations to which both plates are subjected. From a geological point of view, Italy is largely the result of the subduction of the African plate underneath the European plate, with the consequent deformation and uplift of the sediments found on the ocean floor and on the continental margin ” . The African plate was also questioned five days ago, when a 3.8 magnitude earthquake was felt in Milan. “I can’t rule out anything,” the geologists had said in that case.
