Why New Zealand Has More Earthquakes Than Australia

New Zealand sits directly on the boundary between the Australian and Pacific tectonic plates. The Pacific Plate slides past the Australian Plate at about 10 mm per year, causing crustal deformation, volcanic activity, and frequent earthquakes. The country also lies within the Pacific Ring of Fire, a zone containing over 75% of the world's volcanoes and 90% of its earthquakes.

Australia, by contrast, sits near the center of the Australian Plate, far from major plate boundaries. It lacks active volcanoes and experiences far fewer and generally smaller earthquakes.

In short, plate-boundary location makes New Zealand seismically active, while Australia's intraplate position keeps it relatively stable.
