Session 2.2 GNGTS 2023 On the other hand, with equal cost, cheaper sensors allow high-density applications, exactly what is desirable for urban networks (Fig. 1). Urban networks can be established in relatively short times with respect to large-scale networks. Also the costs for their maintenance is comparatively contained. Urban seismic networks can be integrated with other networks in order to achieve multi-parametric infrastructures in a smart-city perspective. Possible integration includes data useful during the phase of post-disaster decision (e.g. structural monitoring, power and water grids, transportation), but also climate and environmental parameters (Ristvej et al., 2020). Remarks Conversely to country-scale seismic networks, the urban networks developed only recently and have been mostly carried out as experimental or temporary systems. Because of their tasks and their contained cost, their implementation should be considered at least the urban areas characterized by the highest seismic risk. They enable several crucial functions, either in the mitigation phase before a strong event, but most of all when the event is ongoing (e.g. early warning system) and just after the event, when the support to decisions and rescue operations are crucial. The urban seismic network should be considered as a component of a, multi-scale, multi-parametric system which carries out several roles in the disaster cycle, both in the pre-event (preventions) and post-event (recovery) phases (Fig. 3). The potential outcomes of an integrated multi-scale system for the earthquake risk reduction would be for the civil society, for the civil protection and decision makers, and for the scientific community.
