National Earthquake Information Database
This database provides raw and derived data related to earthquakes in New Zealand. Available to the public and researchers, this data aims to facilitate the creation of new knowledge through research into geological hazards, informing responses to geohazard events. This is a Nationally Significant resource.
Nationally Significant Databases are those datasets and collections registered as important for New Zealand, and as such, they are supported by long-term government funding.
The EID consists of a number of datasets, including:
- The earthquake catalogue(external link) – This contains information about earthquake occurrence such as location, magnitude and arrival times of seismic waves.
- Moment tensors(external link) – This describes the magnitude and source mechanism of an earthquake, i.e. the geometry of how the fault ruptured in the earthquake.
- The waveform archive(external link) – This contains data from the digital seismic recordings.
- Station metadata(external link) – This holds information relating to the GeoNet sensor network.
- Felt Reports(external link) – This compiles records of the intensity of shaking that people experience during an earthquake.
- Strong motion data products(external link) – These are derived from strong-motion accelerometers that are located in major centres of population, near significant faults, or in different types of building structures.
- Fault Rupture Models(external link) – This is a compilation of rupture models from the published literature in a common format.
The database also includes predigital data, in particular historical seismograms and felt reports. These are mostly paper seismograms with some film. Non-digitised historic data can be made available on request.
