1703 Apennine earthquakes
[1] A total of about 10,000 people are estimated to have died as a result of these earthquakes,[2] although because of the overlap in areas affected by the three events, casualty numbers remain highly uncertain.The central part of the Apennines has been characterised by extensional tectonics since the Pliocene epoch (i.e. about the last 5 million years), with most of the active faults being normal in type and NW-SE trending.[6] Modern estimates give a maximum Mercalli intensity of XI (Extreme).Marine ridge, a large slope failure near Posta and liquefaction along the Aterno River.[9] Details taken from Catalogue of Strong Earthquakes in Italy (461 BC – 1997) and Mediterranean Area (760 B.C.
