Earthquake in Milan: “Never a shock so strong in the last 500 years” – Chronicle

Milan, December 17, 2020 – The earthquake was felt today in the Milan area it was the most trembling strong earthquake with epicenter in the Milan area of ​​the last 500 years. According to Lucia Luzi, head of the Milan section of the National Institute of Geophysics and Volcanology (Ingv), that of Milan “is an area that historically has never experienced great seismicity.” “Looking at the historical catalog of earthquakes, we have to go back 500 years to find a ‘twin’ shock to the current one, with an epicenter in Milan and magnitude 3.7. Other major historical earthquakes occurred in neighboring areas, such as Monza in 1396, with a earthquake with an estimated magnitude of around 5, and then an earthquake on the border with Piedmont in 1918, with a magnitude of 4.6 “. The epicenter was found in Trezzano sul Naviglio. the mayor Fabio Bottero reported numerous messages from citizens concerned about the earthquake. Fortunately, no particular critical issues were recorded.

The area affected by this afternoon’s seismic event is considered a moderate seismic hazarda, reports the National Institute of Geophysics and Volcanology. Looking at the seismic history of Milan (DBMI15) – explains INGV -, which are the intensities produced by the different earthquakes and for which we have precise information about the locality, it is observed that only in one case there was an intensity equal to VII Degree MCS in Milan, on the occasion of the 1117 earthquake in the area of ​​Verona of magnitude 6.5. Intensities equal to VI or V-VI MCS degree in Milan were produced by the earthquakes of 1222 in Bresciano-Veronese (M 5.7), of 1806 in Reggiano (M 5.2), of 1851 in Valtellina (M 4.7) and of 1951 in Lodigiano (M 5.2). In the recent period, from 1985 to today, the region has been affected by moderate seismicity: there have been 9 earthquakes with a magnitude equal to or greater than 3.0 and about 100 with a magnitude equal to or greater than 2.0 in a radius of 50 km around Milan. At present, there have only been 2 earthquakes in the vicinity of the epicentral area: a magnitude 3.0 event in 2002 and a magnitude 3.4 event in 2005, both southwest of Milan.
