380 GNGTS 2022 Sessione 2.2 Conclusion. The assessments of the coverage of seismic and strong motion networks (and consequently their performance) are not only desirable but also of crucial importance to find areas where the networks need to be concentrated or, conversely, where the networks are redundant. the approach of Siino et al. , (2020), based on descriptive spatial statistics, could be a very informative tool to assess the degree of coverage of already developed networks as a function of the spatial distributions of other parameters (including complex and irregular distributions. It also can be exploited to compare different strategies in earthquake monitoring developed in different countries. References Chang, C. H., Yih-Min, W., Da-Yi, C., Shin, T.
