n seismology, the swift deployment of seismic stations following an earthquake event is crucial for optimizing network coverage, facilitating accurate aftershock localization and characterizing the ongoing seismic sequence. SISMIKO [Moretti et al., 2023; DOI 10.3389/feart.2023.1146579] at Istituto Nazionale di Geofisica e Vulcanologia (INGV) is an operational group specifically designed for the rapid installation of seismic stations in post-earthquake scenarios. Comprising trained personnel equipped with state-of-the-art technology, this group operates with the primary objective of augmenting existing seismic networks in epicentral area to capture aftershock activity comprehensively. Since 2008, thanks to the experience acquired during a series of destructive seismic sequences (i.e. L’Aquila in 2009, Po Plain in 2012 and Central Italy in 2016), SISMIKO worked for codifying a set of procedures that are now in place and that allow to provide a rapid response after an earthquake, managing preconfigured metadata parameters, the real-time centralization of all temporary seismic stations and a dedicated data acquisition system. This guarantees fast data availability for research purposes without any restrictions, and, if necessary, supports the INGV monitoring room 24/7 seismic surveillance system. For example, after the Mw 5.5, 9 November 2022 Costa Marchigiana offshore earthquake, data from seven rapidly deployed seismic stations were online within twelve hours from the event occurrence, aiding seismic emergency response. The scientific community can get high-quality data acquired by the SISMIKO group through the Italian node of the European Integrated Data Archive (EIDA [Danecek et al., 2021; DOI: 10.1785/0220200409.]). To better support the Open Science paradigm and the FAIR principles, data streams related to each seismic sequence are identified through Digital Object Identifier (DOI) assigned by the Data Registry [INGV DMO, 2020; DOI: 10.13127/data- registry], and they integrate those available from the permanent Italian National Seismic Network. Furthermore, these procedures also facilitate the recovery and standardization of continuous digital waveform datasets from the past 20 years, supporting global seismic activities and hazard studies. This rapid dissemination of data can support activities of the global seismological community, enhancing timely comprehension of earthquake sequences and facilitating seismic hazard studies.
