意大利强震数据库包含了1972年至2004年期间1004次地震产生的2182个三分量波形，最大震级为6.9级（1980年伊尔皮尼亚地震）。该数据库致力于为地震学和工程界提供服务，可以在http://itaca.mi.ingv.it上在线访问，其中广泛的搜索工具使用户能够交互式地搜索事件和记录站，并检索具有特定特征的波形。用户可以通过图形用户界面（GUI）指定参数。一系列显示选项允许用户在不同的背景下查看数据，并提取和下载时间序列和光谱数据。
The Italian strong-motion database contains 2,182 three-component waveforms generated by 1,004 earthquakes with a maximum magnitude of 6.9 (1980 Irpinia earthquake) for the period from 1972 to 2004. The database is devoted to serving the seismological and engineering communities and can be accessed online at http://itaca.mi.ingv.it, where a wide range of search tools enables the user to interactively search events and recording stations and retrieve waveforms with particular characteristics. The user can specify parameters through a graphical user interface (GUI). A range of display options allows users to view data in different contexts and to extract and download time series and spectral data.
The database was created during a joint project between the Istituto Nazionale di Geofisica e Vulcanologia (Italian Institute for Geophysics and Volcanology, INGV) and the Dipartimento della Protezione Civile (Department of Civil Protection, DPC). The aim of the project was the collection, homogenization, and distribution of data acquired over the time period 1972–2004 in Italy by different Italian institutions, namely Ente Nazionale per l'Energia Elettrica (Italian Electricity Company, ENEL), Ente per le Nuove Tecnologie, l'Energia e l'Ambiente (Italian Energy and Environmental Organization, ENEA), and the DPC. The project had multiple purposes, such as permanent strong-motion monitoring and temporary monitoring during seismic sequences or before permanent installation.
This database updates the ENEA strong-motion data collection, which ended in 1993, and the European database, where the most recent Italian data pertain to the Umbria-Marche sequence of 1997–1998 (Ambraseys et al. 2002). In addition, we reviewed strong-motion metadata and data processing to increase data quality and reliability.
This article describes the project and provides an overview of the search capabilities available at the database interface Web site.
The database was created and implemented in three main steps:
1. Definition of the database schema
2. Collection and processing of waveforms
3. Review of …
