The deadliest earthquake in New Zealand's history occurred in 1931 due to tectonic plate movement. This event was part of the complex interactions of the Pacific and Australian tectonic plates, which are constantly shifting and can result in significant geological activity, including earthquakes. The 1931 Hawke's Bay earthquake registered a magnitude of 7.9 and caused substantial destruction, particularly in towns like Napier and Hastings. The intense shaking and subsequent damage led to the loss of numerous lives and significant economic impact.

Tectonic plate movement is the primary driver behind earthquakes, as it involves the slow and powerful shifts of the Earth's crust. This geological activity is shaped by processes such as the convergence or divergence of plates, which can cause stress to build up until it is released in the form of an earthquake. In contrast, volcanic eruptions, tsunamis, and flooding are distinct phenomena that, while they can occur in relation to tectonic activity, did not cause the 1931 earthquake. Understanding the link between tectonic movements and seismic events is essential in recognizing the primary causes of such destructive natural disasters.
