An earthquake, rated at IX (Violent) on the Mercalli intensity scale, struck northern Italy and Germany on 3 January 1117.Damage in southern Germany and Pisa were initially attributed to this single event in the works of early scholars, however, they are now widely accepted that three distinct earthquakes occurred within the span of several hours.The first earthquake affected the towns of Augsburg, Dissibodenberg, Freising, Petershausen, Saint Blasien and Zwiefalten of Germany, and Melk and Salzburg in Austria.[6] The Milanese chronicler Landolfo Iuniore reported that the church synods needed to be carried out in the open air due to the destruction.The Michaelskirche in Bamberg, the abbey at Brauweiler, and buildings in Rottenburg am Neckar, Constance, Meersburg, and Fénis were all reported damaged.
