Geonet quakes

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.

The full and detailed information about the earthquake, such as uncertainties, geonet quakes, arrival times and amplitude picks, location algorithm and velocity model used, can be found in the QuakeML file for each earthquake.

This application allows you to search the New Zealand earthquake catalogue using temporal, spatial, depth and magnitude constraints, build 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. Please refer to Catalogue Output for descriptions of the fields and our recommendations for rounding. The data are made available under the GeoNet Data Policy.

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. Category Utilities. Read more about Shaking Layers maps. For the last 2 or so years I have struggled to get some of the earthquakes that I have selected over light and above. Features of Quake Search: You can search by geographic location, magnitude and time. 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. Displays recent quakes in a list or map, filter them by intensity. These can include tsunami, landslide, liquefaction, and land deformation and movement. The magnitudes from all available stations are then averaged to give an overall value for the event. Use the Shaking Layers API to automatically update your program with the latest run files for an event. Manual configuration steps. About Shaking Layers data The Shaking Layers Map shows ground shaking models produced from a combination of strong motion measurements and ground motion modelling that estimate the shaking intensity around New Zealand. However the font size of the contour numbers is too small. It does not include arrival times, origin history or additional magnitude information. Fiordland Gisborne.

Webservice, includes event, station and waveform services. Data Clock. It revealed the existence of a hidden west-east fault under the gravels of the Canterbury Plains. The earthquake that shook Marlborough on Monday, 16 October was the largest in a series of earthquakes to hit the region that year. Magnitude 2. Disaster Alert. The electrical current is digitised and transmitted continuously in real time and forms the raw data used to detect and analyse earthquakes. For smaller quakes the GeoHazard Analysts still produce verified and refined solutions, just with less time pressure! These locations cannot be considered reliable. Learn More.
