Strong-Motion Databases
-> The European Strong Motion Database (ESD)
This platform provides an interactive, fully relational database and databank with more than 3.000 uniformly processed and formatted European strong-motion records and associated earthquake-station and waveform-parameters. The user can search the database and databank interactively and download selected strong-motion records and associated parameters. Information about European organizations involved in strong-motion recordings are also available.
The objectives of this project in the frame of the 5th Framework Programme of the European Commission, Research-Directorate General, Environment and Climate Programme are:
i) to establish a freely accessible platform of a reliable strong-motion databank and associated database of seismological parameters of earthquakes in the greater European area.
ii) to install the platform on the Internet at Imperial College of Science, Technology and Medicine in London (United Kingdom) with identical sites at University of Iceland in Reykjavik, at University of Trieste (Italy) and at the Institute of Engineering Seismology and Earthquake Engineering in Thessaloniki (Greece)...
-> PEER Strong Motion Database
The PEER Strong Motion Database contains 1557 records from 143 earthquakes from tectonically active regions, processed by Dr. Walt Silva of Pacific Engineering using publicly available data from Federal, State, and private providers of strong motion data.
The Pacific Gas and Electric Company, the California Energy Commission, and the California Department of Transportation have sponsored the development of the strong motion database as part of the PEER Directed Studies program on lifelines. The National Information Service for Earthquake Engineering, sponsored by the National Science Foundation, is responsible for programming and distribution of the database.
The processing of the strong motion records in the PEER database is in general different than the processing done by the agency that collected the data. Although the processed records may be different, the differences should be small within the frequency passband common to both processing procedures.
-> Consortium of Organizations for Strong Motion Observation Systems (COSMOS)
The purposes of COSMOS are to:
1. Develop national policies and foster innovative ideas for the urgent improvement of strong-motion earthquake measurements and their applications;
2. Promote the advancement of strong-motion measurement on the ground and in structures and lifelines in densely urbanized areas and other locations of special significance to society likely to be struck by future earthquakes;
3. Encourage and assist the rapid, convenient, and responsive distribution of strong ground-motion data according to standards of the Consortium;
4. Serve as a consortium through which programs, institutions, and engineers can work to solve mutual problems with recording instruments of all appropriate types, data formatting and dissemination, and data utilization; and
5. Improve user influence on data acquisition and multipurpose data dissemination...
-> National Geophysical Data Center (NGDC)
NOAA is an agency that enriches life through science. Our reach goes from the surface of the sun to the depths of the ocean floor as we work to keep citizens informed of the changing environment around them.
The Earthquake Strong Motion CD-ROM Collection
The National Geophysical Data Center's entire strong motion three CD-ROM collection containing over 15,000 digitized and processed accelerograph records is available
online. The data represent a broad range of structural and geologic recording environments. Three types of processed records are included on the CDs: uncorrected (raw), corrected (filtered), and response spectra (includes Fourier spectra)...
-> Northern California Earthquake Data Center
The Northern California Earthquake Data Center (NCEDC) is a joint project of the University of California Berkeley Seismological Laboratory (BSL) and the United States Geological Survey (USGS). The NCEDC is a long-term archive and distribution center for seismological and geodetic data for Northern and Central California and is partially supported by funding from the USGS component of the National Earthquake Hazards Reduction Program (NEHRP)...
