Geonet quakes

This application allows you to search the New Zealand earthquake catalogue using temporal, spatial, depth and magnitude constraints, geonet quakes queries to request data in different formats, or show search results on an interactive map. Enter search parameters in the text boxes or select values from the default options. The search boundary can be changed by zooming or panning the map after selecting the Map Extent option. Catalogue data are stored at the precision used in the calculations, geonet quakes.

The GeoNet catalogue is where all the technical information about earthquakes is stored. Information such as location, magnitude and arrival times of seismic waves. Since the 's, earthquakes in the catalogue have been determined by instrumental records. Prior to that estimates were made from oral and written records. GeoNet uses a unique combination of numbers and letters to easily identify an earthquake. This is called the earthquake's Public ID.

Computers do the ceaseless job of monitoring seismic data looking for possible earthquakes. Once one has been initially detected, the location and magnitude become refined over a number of minutes as more data from further stations arrives. For smaller quakes the GeoHazard Analysts still produce verified and refined solutions, just with less time pressure! Seismic traces showing P and S arrivals. To make rapid locations of earthquakes GeoNet operates a country-wide network of seismic stations that transmit their data to central data centres and the cloud where it is then analysed by automated processes. Once an earthquake is detected and an automatic location and magnitude is determined for it, its information is released onto the Quakes part of the website. The seismic stations operated by GeoNet consist of a seismometer and a digitiser. A seismometer is a sensitive instrument that generates a small electrical current in response to ground shaking. The electrical current is digitised and transmitted continuously in real time and forms the raw data used to detect and analyse earthquakes. The seismic stations are supplemented by a network of strong motion sensors, which are invaluable for providing records of the strong shaking produced by large or nearby earthquakes. Compared to seismometers, these sensors are very insensitive and can record up to 4 g of ground motion without clipping - something a seismometer could never dream of! The computer processes look for ground shaking that is distinct from the normal background activity such as that caused by weather and human activity and is most likely to have been caused by an earthquake. These occurrences are called detections. Our automatic earthquake detection system tries to group detections in space and time.
