• Resumen

  • The availability of an extensive dataset of seismological data, together with the description of the recording site, can help improve studies on the causes and effects of earthquakes, such as studies on seismic hazard, site-response analysis, soil-structure interaction, seismic source properties, shallow and deep earth structure, and so on.

    The number of seismological stations installed worldwide for either monitoring seismicity at regional or national scale or deployed for specific studies has dramatically increased in the last years. As a consequence, there is a growing need on one hand to archive the huge quantity of acquired data in a safe and organized way and, on the other hand, to provide suitable access and search-capability tools to those data. Several research institutions from different countries currently collect their seismological data into databases, making them available on the Web. Embedded Image A list of the main worldwide, national, and Italian seismological databases is provided in the electronic supplement to this article.

    In this article, we present the OGS Archive System of Instrumental Seismology (OASIS), the new information system developed at the National Institute of Oceanography and Experimental Geophysics (Istituto Nazionale di Oceanografia e di Geofisica Sperimentale [OGS]), settled in Italy, with the aim of organizing, archiving, and providing access to the whole set of its seismological instrumental data.

    OGS is a research institute located in Trieste, northern Italy, which has a well-established seismological tradition and had a relevant growth after the 1976 Mw 6.4 Friuli earthquake with the development of the northeast Italy seismometric network (rts.crs.inogs.it; last accessed February 2015). During the last decades, and especially after 1995 when OGS switched its regional network from analog to digital...
