Earthquake data avaliable on CD-ROM - 09/04/1998

Ground-movement data from New Zealand earthquakes dating back 30 years is now available on CD-ROM.

The data, available from the Institute of Geological & Nuclear Sciences Limited, is expected to valuable to engineers, developers, planners and scientists. It can be used to help develop design options for protecting buildings, structures and community lifelines from earthquakes.

The data has been compiled from the Institute's network of 266 accelerographs and acceleroscopes. They are located throughout New Zealand -- some directly on the ground and others are attached to buildings, bridges and dams.

The instruments make up what is known as the strong-motion network. They measure strong ground-shaking during earthquakes that can damage buildings. The data they collect is extremely valuable for increasing the body of knowledge in design engineering.

The 600 earthquake recordings on the CD-ROM have been fully processed to give instrument-corrected and filtered time histories (accelerations, velocities, and displacements) and response spectra.

Also included on the CD-ROM are support files giving information on the formats of the processed data files, locations of recorded events, locations and coded ground class classifications for the recording sites.

The CD-ROM is available from the Institute for $NZ300 (including GST).
