| Abstract: | This paper tackles the problems connected with the use of macroseismic scales, with particular attention to MSK. Intensity estimates are in principle affected by uncertainties which are seldom quantified in practice. In the case of two localities (Scisciano and Orciano) damaged by two Italian earthquakes (1741, Fabriano and 1846, Orciano), which have a good historical documentation, the difficulties of obtaining the data necessary for MSK evaluation have been analysed. In order to assess the maximum range of uncertainty the data have been analysed in two extreme scenarios. Finally a comparison between intensity assigned using the MSK and MCS scales is analysed. |
