Internet-Site for European Strong-Motion Data

Structure

During the past decade Imperial College of Science Technology and Medicine, London, Ente Nazionale per l'Energia Elettrica, Rome, Ente per le Nuove Tecnologie, l'Energia e l'Ambiente, Rome and Institut de Protection et de Sûreté Nucléaire, Fontenay aux Roses attempted to retrieve, process and analyse strong-motion records, chiefly analogue, from the European, Mediterranean and Middle Eastern regions. This dataset contains information for 1,089 record sets from 482 separate earthquakes and 352 individual strong-motion stations and, in the frame of the EC-project "Dissemination of European Strong-Motion Data" (CD-ROM project), was extended with more than 1,400 new strong-motion records, giving a total of more than 7,500 European component records now held at the Imperial College strong-motion databank. Many of the new records were extracted from the databank of the participants of the CD-ROM project, others were directly provided by network operators, agencies or organizations or were downloaded from the Internet.
It has to be stated, that the growth of this databank depends entirely on contributions from owners of strong-motion stations or data.

The CD-ROM "Dissemination of European Strong-Motion Data" contains:

a databank with 1,068 uncorrected and uniformly corrected strong-motion records and elastic response spectra from Europe and adjacent regions.

a database with associated earthquake-, station- and waveform-parameters.

a browser-program for searching, selecting, visualising and exporting the records and associated parameters.

user documentation.

The databank, database and browser program are the result of our effort to process, archive and uniformly present European "ground response" acceleration time histories that have been recorded between 1971 and 1999. The compilation and processing of this dataset were supported by the European Commission, Directorate General XII, Science, Research and Development, Environment, and Climate Programme, contract ENV4-CT97-0397 (Dissemination of European Strong-Motion Data).

The structure of the data archived on the CD-ROM is shown in the following figure.
