    Description: We present an analysis of the reliability of focal mechanisms obtained through moment tensor inversion at the Irpinia Seismic Network, southern Italy. Our analysis is based on the methods proposed by Zahradník and Custódio (2012) and Sokos and Zahradník (2013). We present two different studies: (1) we compute maps of theoretical focal mechanism resolution for the Irpinia region and (2) we study the reliability of the solutions obtained from waveform inversion of five regional earthquakes. Theoretically, we find that when data error is the dominant source of error, focal mechanism resolution is better close to the spots of higher station density rather than at the center of the network. Using real data, we were able to successfully study four of the five regional events, in spite of the large source–station distances (up to ∼280  km) and significant azimuthal gaps (〉319°). We used variance reduction, double‐couple percentage, signal‐to‐noise ratio, condition number, and focal mechanism variability index to assess the quality of the solutions. Our quality assessment is validated by comparison with independent focal mechanism solutions.

Primarily driven by governmental mandates to detect local seismicity and provide earthquake information to civil protection agencies and the general public, this monitoring effort also results in a tremendous amount of high‐quality data—more than 12,000 stations presently contribute to the European Integrated Data Archive (EIDA)—which is made available to scientists and practitioners. This lively community of seismic data providers and users is at the core of the success of this focus section: 30 groups responded enthusiastically to our call for papers, providing high‐quality contributions that describe the state of the art in observational seismology in the greater European region, addressing all components of the life cycle of seismic data, from station design to open dissemination of data and seismological products (Amato et al., 2021; Bono et al., 2021; Bragato et al., 2021; Büyükakpınar et al., 2021; Cambaz et al., 2021; Carrilho et al., 2021; Danecek et al., 2021; Evangelidis et al., 2021; Galea et al., 2021; Heit et al., 2021; Lanzano et al., 2021; Lenhardt et al., 2021; Lund et al., 2021; Mărmureanu et al., 2021; Margheriti et al., 2021; Masson et al., 2021; Mader and Ritter, 2021; Ottemöller et al., 2021; Quinteros, Strollo,et al., 2021; Quinteros, Carter, et al., 2021; Rudzinski et al, 2021; Péquegnat et al., 2021; Schweitzer et al., 2021; Senturk et al., 2021; Shahvar et al., 2021; Spallarossa et al., 2021; Stammler et al., 2021; Strollo et al., 2021; Veikkolainen et al., 2021).
