Biggest earthquake in 201 years


The September 1, 2016 M 7.1 earthquake northeast of Gisborne, New Zealand is the biggest quake to hit top of the North Island in 20 years.

The largest was a M 7.1 event in February 1995, about 45 km to the southwest of the September 1, 2016 earthquake. The 1995 event also occurred as a result of shallow oblique-normal faulting, and is not known to have caused any fatalities or damage. The 1995 M 7.1 earthquake was followed by a M 6.5 aftershock five days later.

Tectonic Summary


The earthquake occurred as the result of shallow oblique-normal faulting near the plate boundary between the Pacific and Australia plates.

The current event was preceded by a M 5.8 foreshock, approximately 18 hours earlier and 30 km to the north, at a similar depth and with the same faulting mechanism as the subsequent M 7.1 earthquake.
