National Warning: Tsunami Marine and Beach Threat CANCELLED 

Issued at 08:30 NZST 02 September 2016

The Ministry of Civil Defence & Emergency Management (MCDEM) has cancelled the tsunami marine and beach threat warning in place for the North Coast Regions of the North Island of New Zealand.


Based on all available data, the greatest tsunami activity has now passed. However, coasts may still experience unusual, strong currents and sea level fluctuations lasting for several more hours.

At 4:37am today a magnitude 7.1 earthquake struck 100km off the coast of East Cape. The tsunami experts panel is active and is assessing the situation with the Ministry of Civil Defence and Emergency Management (MCDEM).

Shaking was felt throughout the North Island, with nearly 5,000 felt reports reported to GeoNet within the first 20 mins of the earthquake. As at 7:10am there have been 57 aftershocks, the largest, is a magnitude 6.2 quake. Aftershocks can be expected to continue for some time. This morning's quake was preceded by a magnitude 5.7 foreshock at 10:04am yesterday which occurred in the same area. (Note: there is no way to tell if an earthquake is a foreshock, only when the larger quake occurs can we call it a foreshock).

This area is no stranger to large earthquakes. In February 1995 there was a magnitude 7.2 earthquake off the coast of East Cape, further to the south than this morning's earthquake.

If you felt this earthquake, we'd like to learn more about your experience. You can now fill in Felt Detailed here. This longer form felt report takes a bit more time than our Felt Rapid system but it provides valuable information to our scientists about the earthquake.
