Earthquake emergencies in Italy: SISMIKO operational task force for seismic networks rapid deployments and integration in the monitoring system

Abstract

SISMIKO is the operational task force at the Istituto Nazionale di Geofisica e Vulcanologia aiming at the rapid deployment of temporary seismic stations in the area hit by a significant earthquake or a seismic sequence causing concern and interest with impact on people. Decreasing the average distance between the seismic stations improves network detection, accuracy of the earthquake locations, shakemaps and strong motion parameters. The data acquired by SISMIKO are available, without any constraints, to the entire scientific community through the EIDA portal Italy node, which assures a high level of data quality. A national diffusion of the preconfigured seismic stations in different headquarters and a ready acquisition system, guarantee rapid response after an earthquake and allow the immediate acquisition of the data as soon as each seismic station is installed. An international FDSN network code is registered in advance and a five char codification for the station names is applied to request the ISC station codes (T<emergency identifier><headquarter identifier>). The last emergency (no. 17) in 2022 was caused by an earthquake of Mw 5.5 in the Costa Marchigiana region, where we installed eight stations of the Y1 network the same day as the mainshock (DOI: 10.13127/SD/TBLKBA-3U6). We present the organization and the objectives of the SISMIKO operational group and the analysis of the dataset of the latest seismic sequence carried out by the seismic surveillance service, the Italian Seismic Bulletin (BSI) and SISMIKO.
