Many historical documents, manuscripts and archives from the old church had been moved to the new church of Santa Maria del Principio, and were also lost in the destruction caused by the eruption. Ironically the hilltop church was not as badly damaged. However very few buildings in the town were spared, including another church, "San Giorgio Vecchio" and the Torre Ummarino – a newly constructed tower. It is not known how many people from San Giorgio, if any, were killed in the 1631 eruption, but records indicate the population was decimated. Whether this was from loss of live, or evacuation is unclear. It has been estimated though, that more than 3,000 people were killed throughout the region in the December 1631 eruption, and from the physical destruction within San Giorgio a Cremano, it can be surmised that many of the dead may have lived there.
