About Earthquake Activity in New Zealand
New Zealand straddles the boundary between the Pacific and Australian plates. Learn more about seismic activity in New Zealand below.
The largest earthquake recorded in New Zealand in the past 100 years was M7.8 in 2009 (97 km WSW of Te Anau, New Zealand). The region is defined by Alpine Fault, Hikurangi Subduction Zone, Wellington Fault, and the risk level is classified as High.
With a population of 5.1 million, understanding local seismic hazards is crucial. This page provides real‑time USGS data and historical context for New Zealand.
Why does New Zealand experience earthquakes?
New Zealand lies on Pacific Plate colliding with Australian Plate. The movement of these plates builds up stress, which is released as earthquakes. In subduction zones, one plate dives beneath another, generating some of the largest quakes on Earth. In strike‑slip regions like the San Andreas, plates slide past horizontally.

Frequently Asked Questions about New Zealand Earthquakes
❓ What was the strongest earthquake in New Zealand?
The largest earthquake recorded in New Zealand in the past 100 years was M7.8 in 2009 (97 km WSW of Te Anau, New Zealand).
❓ Is New Zealand on a fault line?
Yes, New Zealand is crossed by Alpine Fault, Hikurangi Subduction Zone, Wellington Fault, making it prone to seismic activity.
❓ How often do earthquakes occur in New Zealand?
Due to its tectonic setting (Pacific Plate colliding with Australian Plate), New Zealand experiences hundreds to thousands of earthquakes each year, though most are too small to feel.
❓ What should I do during an earthquake in New Zealand?
Drop, cover, and hold on. Stay away from windows, and if outdoors, move to an open area. After the shaking stops, check for injuries and be ready for aftershocks.
