[S05-1-03] The contribution of the Sismos project to the preservation, dissemination and scientific usage of the material heritage of instrumental seismology of Euro-Mediterranean area

Graziano Ferrari (Istituto Nazionale di Geofisica e Vulcanologia, Rome, Italy)

invited

In view of the long Italian tradition in instrumental earthquake observation, on 2001 INGV officially started the Sismos project for the research, recovery, high resolution scanning and dissemination of seismograms recorded in Italian and Euro-Mediterranean area observatories during the period 1895 -1984 (sismos.rm.ingv.it/en/). The Sismos High resolution scanning laboratory is equipped with 3 flat bed A0 format scanners, and the seismograms are scanned at 1016 dpi grey scale.
A major effort was made to intervene in the different sectors (scientific, historical, cultural and popular dissemination) with the disciplinary rigour of the different disciplines and synergies involved as compared with analogous initiatives at the national and the international level.
During the period 2006-2010 SISMOS was part of the facilities of the European project NERIES, from 2010 and 2012 participated to the GEM project, and is also a seismological infrastructure (History and data of instrumental seismology) of the European Plate Observing System (EPOS).
SISMOS pays also particular attention to the recovery, restoration and conservation of historical materials relating to Italian and international seismology with scientific as well as cultural aims.
Since 2008, two restoration laboratories have been set up at Sismos, one for historical papers (i.e. seismograms, bulletins, etc.) and one for historical instruments.
Since 2005, SISMOS has developed a specific software for the viewing and processing of raster images of historical seismograms into a vectoral form: Teseo2 - Vectorizer of historical seismograms (teseo.rm.ingv.it/). The program has been extensively used by SISMOS researchers and foreign colleagues.
A new database and a new interface of the SISMOS portal make more efficient the request and download of some of the over 200,000 seismograms' raster images (seismogramrequest.rm.ingv.it) and relevant instrument's constants (over 20,000) and station bulletins (over 500,000 pp).
