| Video Discription | San Francesco in Assisi is an Italian Gothic building begun c.1228 and consecrated 1253. "The sequence of events for this seismic event is as follows: At about 2:30 AM, a 5.7 magnitude earthquake hit the basilica. Coincidentally, Ghigo Roli, a photographer who had been photographing the Upper Basilica’s frescoes for months, happened to be in the basilica during the event. In his testimony of the first tremor, he recalls that immediately after the first tremor the air was filled with dust, and the floor was littered with chips of frescoe paint. Upon his initial inspection of the church, Roli notes that a large crack had formed on the great arch along the south face of the transept and a large stone had fallen from the double lancet from a column on the North side of the basilica. This was all of the damage witnessed by Roli that night, which by his testimony, seems to have been limited to non-structural damages. The next morning at about 11:42 AM, a second tremor of magnitude 8.5 hit the basilica. This time, Roli was just outside the doors of the Basilica and a camera crew from Umbria TV was at the front of the nave videotaping. Roli reports that the jambs of the Basilica’s doors rose, then fell while “lurching first forward then back...” (quote from BA thesis by Emidio Piermarini, https://core.ac.uk/download/pdf/18321813.pdf ) Much of the fresco on the vault's surface (St Jerome, early 1290s by the Roman Masters of the St Francis cycle) was recovered and was partly reconstructed. The structure has been fitted with devices that allow the facades to flex in any future quakes, and the roof above, largely of masonry and reinforced concrete (latter of 1953) strengthened with steel. Four people died under this collapse, two surveyors and two friars. |
