Résumé en anglais
In its history many earthquakes have hit the Basilica of St. Francis, which was built in the 13th century. Important earthquakes occurred in 1279, 1328, 1703, 1747, 1781, 1799,1832, 1859, 1917, 1979, and yet none produced damage as great as that which hit central Italy during the night of September 26, 1999, as well as the second that struck the Basilica at 11,42 a.m. The result was the destruction of the vaults close to the façade, of those close to the transept, of a portion of the left transept and the production of large cracks and permanent deformation all over the vaults of the Basilica, leaving them ina very precarious and dangerous condition. Besides the differing impact that the earthquakes of different characteristics, which followed each other during the centuries, may have produced on the Basilica, other factors have increased the vulnerability with respect to the past.
