GeoNet monitors earthquakes, large landslides, volcanoes, tsunami, and movement of land. [1] [2] This monitoring is done using over 1,000 instruments across the country, [1] with data being transmitted from its sensors to GNS Science's computers in Wellington and Wairākei. On average, the monitoring system detects over 20,000 earthquakes per year.
About 14,000 earthquakes occur in and around the country each year, of which between 150 and 200 are big enough to be felt. [2] As a result, New Zealand has very stringent building regulations.
