The Armedea GIS database has been defined in order to collate archaeological evidence relating to medieval seismic activity, such as data from excavations, architectural evidence preserved on standing buildings, and environmental effects such as tsunamis and landslides. The database therefore presents a hierarchical structure that, for each event, allows the organisation of general information relating to the earthquake (level 1: name, date, epicenter, magnitude, intensity, sources, references, etc.), the related affected places (level 2: name of the locality, intensity, type of information, etc.), shown as Macroseismic data points (MDP; data source: AHEAD archive), and the archaeological effects (or the documentary sources that recorded them) within each MDP point (level 3: data from excavations, architectural evidence, tsunami, landslide, with details). This catalogue will allow us to implement queries about the quality and geographical distribution of information, the nature of the damage and strategy of response relating to the medieval earthquakes in Europe during the period 1000-1500 AD from an archaeological perspective.
Earthquakes occurring up to the beginning of the 12th century have been recorded so far, and the images show some examples from the Veronese earthquake (1117, highest intensity = 9) file. Within the map on the top, points indicate some of the places affected by the earthquake (the yellow star symbolises the epicenter), whereas the screenshot on the bottom shows the damaged buildings in Verona, according to the historical evidence (from Guidoboni, Comastri 2005, Catalogue of Earthquakes and Tsunamis…, pp. 84-126).
