Subject Classification: | 04. Solid Earth::04.06. Seismology::04.06.05. Historical seismology | Abstract: | The 13 april 1558 earthquake was located midway between Siena and Florence (Tuscany) with epicentral intensity VI-VII MCS and magnitude 4.6 by the CPTI Working Group (1999) catalog. The historical data set from which these epicentral parameters were derived is extremely scanty: two low macroseismic intensity data points (Florence and Siena) and vague mentions of "more damage" in the intermediate area. By mean of a targeted archive research, the data set has been very much improved (from 2 to 21 macroseismic intensity data points) and a new set of epicentral parameters has been assessed, turning a comparatively minor damaging event into one with epicentral intensity IX MCS and magnitude 5.8, located in Valdambra, an area with no extant record of seismic activity before this study. |
