There is little information about earthquake damages prior to the 20th century. In 1957, the sphere at the top of the bell tower fell. The August 28, 1973 earthquake cracked several walls and left two walls off balance. The earthquakes of 1985, 1999, and September 7, 2017 did not cause serious damage to the building, but the September 19, 2017 earthquake did. The bell tower was almost completely separated from the main building, and the cupola was completely destroyed. Other damages were so severe that it is possible the building will no longer be used as a church.
