The 1511 Eastern Alps earthquakes: a critical update and comparison of existing macroseismic datasets

Three earthquakes condition the seismic hazard estimates of the Eastern Alps: the 1348 "Villach", the 1511 "Idrija", and the 1976 Gemona events. Only the last one can be well documented, while doubts remain for location and size of the other two. New documents have been found about the 1511 quake that, together with a complete revision of the information already available, offer some new indications on the location and size of the event.
