The timestamp shown at the top right of the images is the time when the images were last refreshed. The previous 36 hours of sea level variations from all operational sites are displayed, oldest to ...

The timestamp shown at the top right of the seismograph drum shown above is the time when this image was last refreshed. The previous four hours (240 minutes) of seismic signals (also known as traces) ...

An interactive, multi-layered map displaying the peak strong motion data that GeoNet collected during the last hour. Select a site to view the PGA (g), PGV (cm/s) and MMI values. Sites are coloured to ...

Felt earthquake reports are quantified using the New Zealand Modified Mercalli (MM) intensity scale. The MM scale grades the impact of an earthquake on people living on the earth's surface, and so can ...

The tsunami that was caused by a M 9 earthquake in Chile hit the shores of New Zealand in the early hours of 15 August, taking 15 hours to arrive here. The tsunami and earthquake killed thousands of ...
