GeoNet Aotearoa New Zealand Earthquake Catalogue
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.

Earthquakes in the catalogue prior to the twentieth century are not based on instrumental readings. These have been collated from Māori history and accounts in newspapers, books and diaries. By comparing shaking and damage reports from different towns and settlements, likely epicentres and magnitudes have been assigned. Geological evidence, such as the movement of surface faults or landsliding, can also improve the magnitude estimate, but only the very largest earthquakes leave a fault trace behind. Even once instruments started to be installed in New Zealand after 1884, there were too few of them to comprise a network that allowed earthquakes to be located. It was not until the 1930s that the locations of stations started to form a network, and not until 1942 that it was complete enough to locate some earthquakes with any confidence. Computers were first used in New Zealand to locate earthquake origins and determine magnitudes in 1964.
