Managing natural hazards

New Zealand’s preparation and advice

Why do some countries experience more frequent and intense natural hazards than others? When these occur, why do some countries cope with them better? And what can be done to prepare for an earthquake? These are just a few questions that this article seeks to answer with a focus on New Zealand.

Visit the website www.geonet.org.nz/earthquake and study the map showing recent earthquakes in New Zealand. The list on the left shows how recent and frequent earthquakes have affected people. Few places on New Zealand’s two main islands avoid this natural hazard.

The colour of earthquake locations on the choropleth maps indicates the seismic intensity. Click on the filter box (upper left), and change ‘Weak and above’ to ‘Moderate and above’ and fewer circles will appear on the map, and only those in darker colours. Click on any circle on the map and an information box opens indicating when this earthquake occurred, its depth, strength (magnitude) and the level of any surface shaking.
