The quake was localized by the seismographs of the Ingv of Rome and of the Institute of Geophysics and Volcanology, two kilometers from Bonate Sotto, Municipality of Bergamo, to one depth of 26 kilometers. The earthquake was clearly felt in the center of Milan, but also in the hinterland of Segrate, Vermezzo, Como, Pavia and in Brianza. The earthquake would have been felt more strongly in the Vimercatese area.
Second shock in Osio Sotto
A second earthquake, less strong than the first, was recorded in the Bergamo area: this time the epicenter was located in Osio Sotto, at 11.57, at a depth of 24.9 kilometers, according to data from the National Institute of Geophysics and Volcanology. The aftershock was of magnitude 2.2, therefore half of the previous one with its epicenter in Bonate Sotto: it was perceived, but with less intensity than the first. The two countries are about ten kilometers apart. There are no damages or injuries not even for this second shock. Many calls to firefighters and law enforcement agencies.
The president of Eng
“It’s a tearthquake that we define light, between 4 and 5 are relatively low, in Italy earthquakes usually cause damage when they are over 5.5 “: this is how Carlo Doglioni, president of Ingv, analyzes the earthquake this morning. If the quake did not cause damage it is also thanks to the depth of the epicenter: “An earthquake that occurs in depth the energy that reaches the surface decreases, because – explains the president of the Ingv – the cone of energy that radiates to the surface becomes larger “. As for today’s earthquake,”we are not sure about the depth, we try – says Doglioni – to give an estimate as reliable as possible, but we do not know the speed of the seismic waves that cross the rocks, we estimate an average speed and on the basis of that average we hypothesize the depth. The earthquake could be even beyond 30 kilometers, no one can descend to that depth, which we estimate even with past earthquakes. It is not easy to have a CT scan of the whole national territory “.
No critical issues in Milan
At the moment “no particular critical issues” in Milan due to the earthquake felt distinctly in the city. The firefighters communicate this, adding that “the teams are still inside their premises”. “At the moment there are no reports of damage in Milan. Operations centers are careful to monitor every possible critical situation. “This was reported by the councilor for safety Marco Granelli.
