The map and table above show earthquakes and reported shaking in New Zealand in the last hour. You can find our strong motion data here.

geological hazard information for New Zealand.

Rapid Strong Motion Data. The maximum horizontal PGA or PGV is taken as the maximum of the two horizontal components. A symbol might be absent for the following reasons: 1) no data was received from the site in the last hour, or 2) if the site has …

FITS Deprecation Notice The FITS data base is being deprecated on the 31st March 2025. The data is being migrated to Tilde and will be available through the API and visualization interfaces. You can check on the status of the different data sets on our FITS System Deprecation: Transition to Tilde API page.

1 天前 · GeoNet combines magnitudes into a summary magnitude, M, which consists of a weighted average of the individual magnitudes and attempts to be a best possible compromise between all magnitudes for a range of earthquake sizes.Summary magnitude for GeoNet is then defined as: M = (2 * MLv + (0.4 * number_of stations(Mw(mB)) - 1) * Mw(mB)) / (2 + (0.4 * number_of_stations(Mw(mB)) - 1)) Where MLv is ...

The NGMC receives live feeds from monitoring equipment located all around Aotearoa New Zealand, provided via the GeoNet system, and data from international stations. Earthquakes are monitored using a nationwide network of more than 500 seismic and strong motion sensors. Landslides are forecast based ...

Over recent months Te Wai ā-moe (Ruapehu Crater Lake) has remained cool but recent data suggest a weak heating trend is underway. The lake temperature is now around 10°C to 11°C, slightly up from the low of 8°C.

New Zealand Strong-Motion Database. GNS Science and GeoNet have prepared a collection of strong motion data resources for significant New Zealand earthquakes.

Frequency of New Zealand Earthquakes (1960 to 2024) Magnitude Annual Average Minimum Maximum "In general" 4.0 - 4.9: 360.22: 124: 1,178 1 per day: 5.0 - 5.9

2024年12月20日 · The most recent SSE started around the beginning of December. Continuously operating GNSS stations just north of the Mahia Peninsula moved by approximately 4 cm eastwards and 1 cm southwards over the past three weeks, with a few centimetres of displacements observed on stations between Wairoa and Tolaga Bay.
