Le résumé fourni par la source

Abstract. This paper illustrates the activities of EMERSITO, an emergency task force of the Istituto Nazionale di Geofisica e Vulcanologia (INGV, Italy) devoted to site effects and microzonation studies, during the seismic sequence that occurred close to the Adriatic coast in Central Italy since November 9th, 2022, following the Mw 5.5 mainshock localised in the sea. In particular, we describe the steps that led to the deployment of a temporary network of seismic stations in the urban area of Ancona, the main city of the Adriatic coastline. Data collected by the temporary Ancona network (identification code 6N, doi: 10.13127/sd/qctgd6c-3a, EMERSITO Working Group, 2024) from November 2022 to the end of February 2023 have been preliminary analysed with different techniques to characterise the deployment sites, and are now available for further and detailed studies.
