In spring 2018 Guidoboni et al. published CFTI5Med, a new, largely revised and updated version of the Catalogue of Strong Earthquakes in Italy and in the extended Mediterranean area (http://storing.ingv.it/cfti/cfti5/). CFTI5Med collects the results of over three decades of research and comprises the reference study for most damaging earthquakes in the Italian parametric earthquake catalogue (https://emidius.mi.ingv.it/CPTI15-DBMI15/).

CFTI5Med supplies not only parametric data, but also 42,663 macroseismic intensities assigned to individual localities, plus a set of 39,924 historical-critical comments providing general descriptions for each earthquake sequence and for each affected locality. CFTI5Med hence provides a synthetic account of the territorial impact of the earthquake and of the resulting social and economic upheaval. This information is complemented by 2,337 descriptions of earthquake-induced effects on the natural environment.

For every investigated earthquake sequence CFTI5Med supplies the relevant bibliography in an organized form, allowing the reader to navigate upstream from the parameters of a specific earthquake to the original sources used to investigate it. Overall CFTI5Med makes available as searchable PDF files 23,538 of the 47,211 witnesses used for compiling it, many of which are extremely rare or kept in rather inaccessible repositories.

A totally re-designed, more efficient web-GIS interface allows both expert and inexperienced users to fully appreciate the information stored on over 1,259 Italian and 475 Mediterranean damaging earthquakes. The new CFTI5Med website is in fact an advanced e-infrastructure that was designed to navigate its diverse contents at different levels and that can be replicated in any country endowed with a rich pre-instrumental earthquake history.

Finally, starting from CFTI5Med we developed CFTILab, a virtual historical seismology lab offering recently developed tools for locating historical earthquakes, comparing different events or investigating complex earthquake sequences in space and time.
