Abstract
In August 2016, a magnitude 6.0 earthquake struck Central Italy, starting a devastating seismic sequence, aggravated by other two events of magnitude 5.9 and 6.5, respectively. After the first mainshock, four Italian institutions installed a dense temporary network of 50 seismic stations in an area of 260 km2. The network was registered in the International Federation of Digital Seismograph Networks with the code 3A and quoted with a Digital Object Identifier (https://doi.org/10.13127/SD/ku7Xm12Yy9). Raw data were converted into the standard binary miniSEED format, and organized in a structured archive. Then, data quality and completeness were checked, and all the relevant information was used for creating the metadata volumes. Finally, the 99 Gb of continuous seismic data and metadata were uploaded into the INGV node of the European Integrated Data Archive repository. Their use was regulated by a Memorandum of Understanding between the institutions. After an embargo period, the data are now available for many different seismological studies.
Highlights
Background & SummaryTemporary seismic networks, installed few hours after high-magnitude earthquakes, are important tools for understanding the seismic phenomena under several perspectives[1,2].In particular, the continuous ground motion recordings, organized in a standard international format, can be used to: improve the ability to detect the seismicity as well as to follow its spatial-temporal evolution[3]; www.nature.com/scientificdata/ ITALY VissoMw 6.5 2016/10/30 06:40 GMT NorciaMw 5.9 2016/10/26 19:18 GMTMw 5.4 2016/10/26 17:10 GMT Amatrice RomeMw 5.4 2016/08/24 02:33 GMT
We present the temporary seismic network installed in the Amatrice and Accumoli municipalities (Fig. 2b) and the stages to prepare the large amount of data to be shared with the scientific community
The recorded data has been already analysed with standard techniques[19] to produce synthetic reports (Supplementary Fig. 1) for the aims of the CentroMS, and considerable information have been used for the seismic microzonation studies of the involved municipalities
Summary
Temporary seismic networks, installed few hours after high-magnitude earthquakes, are important tools for understanding the seismic phenomena under several perspectives[1,2]. The recorded data has been already analysed with standard techniques[19] to produce synthetic reports (Supplementary Fig. 1) for the aims of the CentroMS, and considerable information have been used for the seismic microzonation studies of the involved municipalities. This large dataset is really valuable, because it is characterized by a very dense network deployed in the most damaged hamlets and close to the seismic sources of the mainshocks.
