On February 5, 1783, Calabria (Southern Italy) began one long and disastrous seismic sequence

"On February 5, 1783, Calabria (Southern Italy) began one of the longest and most disastrous seismic periods that have ever occurred in the earthquake history of Italy. Between 5 February and 28 March there were 5 very strong shocks (5 February, 6 February, 7 February, 1 March and 28 March 1783) and several hundred minor aftershocks, whose overall effects were devastating on most of the Calabrian territory and in north-eastern Sicily. The most violent shocks first struck (February 5 and 6) the southern Calabria, investing the whole area of the Aspromonte and the Strait of Messina, then (February 7, March 1 and 28) the Stretta di Catanzaro, that is the area included between the Gulf of Sant'Eufemia and the Gulf of Squillace."

The colored circles correspond to the epicentres of the 5 earthquakes stronger than the long seismic sequence of 1783 (5 February, 6 February, 7 February, 1 March and 28 March). The color and the dimensions of the circles indicate the maximum intensity observed Imax (Source: CPTI11).
