The GeoNet earthquake catalogue contains the technical information of all known seismological events. The dataset includes information about the events source parameters such as hypocenter, magnitude, arrival time of seismic phases as well as velocity model used and uncertainties in the parameters. Since the 1930's, earthquakes in the catalogue have been determined by instrumental records. Prior to that, estimates were made from oral and written records. At present, a densified network of weak motion and strong motion sensors is used nationally to monitor events in regions that are affected by large seismic activity and volcanism. Around 20000 events are recorded every year in the catalogue. GeoNet observations and earthquake source parameters are currently used for rapid response, risk assessment and research purposes.

The New Zealand National Seismograph, Acoustic and Coastal Tsunami Gauge Networks digital time-series (waveform) data are archived and publicly available. The time-series include both permanent and some temporary network deployments and are distributed using a number of standard formats and access options. The data comprise readings recorded by seismometers, tide gauges and microphones since the commencement in September 1986 of digital recording in New Zealand. Instrument and site information are held in the GeoNet public metadata repository.

A moment tensor describes the source parameters of an earthquake such as the focal mechanism (the geometry of how the crust ruptured in the earthquake) and the seismic moment (the amount of energy released). Since August 2003 when sufficient broadband seismometers were deployed, GeoNet has been able to routinely compute moment tensor solutions for New Zealand earthquakes with M > ~4. The CSV file of moment tensor solutions is updated when a moment tensor solution is calculated.

GeoNet's network of strong motion stations has evolved into a more sophisticated network that captures the strong ground shaking in New Zealand. This network delivers an ensemble of data products including raw and processed data. The GeoNet strong motion data products are available for earthquakes of magnitude 4.0 and above, including time series, response spectra, peak ground motions and Fourier Spectra. As part of the re-development of these products, this dataset is available in two groups: [1] Volume products for earthquake events from 1966 to 2021 [2] Geocsv products for earthquake events from 1999 onwards More details available herein: Improving our strong motion services: https://www.geonet.org.nz/news/1XEmsZdFNntTw69Q5FC2Nh Overview on volume products: https://www.geonet.org.nz/data/types/strong_motion For data access: [1] Strong Motion Tool (https://strongmotion.geonet.org.nz/#/) [2] GeoNet data site (https://data.geonet.org.nz/seismic-products/strong-motion/) This dataset is funded through https://www.geonet.org.nz/sponsors DOI: https://doi.org/10.21420/X0MD-MV58 Cite dataset as: GNS Science, GeoNet Strong Motion Data Products. https://doi.org/10.21420/X0MD-MV58
