Data have been recorded by the National Accelerometric Network (RAN), operated by the Italian Civil Protection Department - Presidency of the Council of Ministers (DPC), the National Seismic Network, operated by Istituto Nazionale di Geofisica e Vulcanologia (INGV) and regional and international networks operated by several providers. The ITACA portal allows users to query earthquake and station information and ground motion parameters, and to select and download accelerometric (processed and unprocessed) waveforms and response spectra upon user registration. The metadata relative to seismic events and recording stations are revised on a yearly basis according to authoritative sources. Events after January 1st 2017 with magnitude greater than 4 are available at the European Strong-Motion database. This release includes about 8000 strong-motion data recorded during the 2016 Central Italy seismic sequence. Furthermore, it contains the station metadata compiled in the framework of the Annex B of the Agreement 2012-2021 DPC-INGV – “Convenzione” B2. About 600 photos, 450 geological maps, 400 noise measurements and 190 velocity profiles are available. ITACA 2.2 has been compiled under the co-ordination of INGV Milano, thanks to the following contribution: 1) Agreement between INGV and DPC (2012-2021); 2) EU Project EPOS." ; schema:identifier "10.13127/itaca.2.2" ; schema:inLanguage "ITA" ; schema:includedInDataCatalog [ a schema:DataCatalog ; schema:description "Portale dei dati aperti Open Data Portal" ; schema:name "ISTITUTO NAZIONALE DI GEOFISICA E VULCANOLOGIA" ; schema:url "https://data.ingv.it" ] ; schema:keywords "terremoti" ; schema:license "http://creativecommons.org/licenses/by-nc/2.0/" ; schema:name "ITalian ACcelerometric Archive (ITACA), version 2.2" ; schema:publisher ; schema:spatialCoverage [ a schema:Place ; schema:geo [ a schema:GeoShape ; schema:polygon "{\"type\": \"MultiPolygon\",\"coordinates\": [[[ [6,47], [20,47], [20,36], [6,36], [6,47] ]]]}" ] ] ; schema:url "https://data.ingv.it/dataset/10" ; schema:version "2.2" . a schema:Organization ; schema:contactPoint [ a schema:ContactPoint ; schema:contactType "customer service" ; schema:name "Istituto Nazionale di Geofisica e Vulcanologia (INGV)" ; schema:url "https://data.ingv.it" ] ; schema:name "Istituto Nazionale di Geofisica e Vulcanologia (INGV)" .
