Description:
Local-scale seismic networks within urbanized areas have been usually employed for short-living seismological experiments or studies. However the possibility, to install permanent (or long-term) earthquake monitoring networks within urban contexts began in the mid '90s.If, from one hand, this possibility was certainly boosted by the support coming from technological developments (digital devices for acquisition and transmission), from the other, the necessity was also driven by the recent global expansion of many urban centers into large metropolitan areas. Also the awareness of the seismic risk in urban center resulted in the increasing interest in the monitoring these areas, with particular focus the most exposed or the most vulnerable ones. Earthquake monitoring networks especially designed may reveal important tools for several tasks related to the seismic phenomena: from earthquake warnings, to emergency operational tasks during emergencies, or scientific studies. In this paper we refer to such earthquake networks as "Urban Seismic Networks" (USN).Because of the increasing resorting USNs for several applications, we consider useful to provide a comprehensive view of the state-of-the-art of the use of USNs, looking at their global distribution and objectives but, most of all, at their design and at their technical characteristics. We retrieved information about 71 USNs worldwide. The USN objectives, as well the other characteristics, have been classified into prearranged groups in order to provide to easily synthesize the various features of the USNs. This review will represent a reference and a guideline for future implementation of USNs.
