Static Maps

Maps showing the national-scale geophysical networks and detailed regional views.

National Network Maps

Select this seismograph network map for a larger version.

The seismograph network consists of primary sites located at approximately 100 km spacing, with further sites established at places of geophysical significance.

Select this continuous GPS network map for a larger version.

The continuous GPS network is a set of locations throughout New Zealand whose exact position is determined using the geometry of satellite orbits. Once again, further sites are located at places of geophysical significance.

Select this strong motion accelerograph network map for a larger version.

The strong-motion accelerograph network consists of instruments with the capability to measure extremely high accelerations associated with large, damaging earthquakes.

Select this tsunami gauge network map for a larger version.

The tsunami gauge network consists of pressure sensors with the capability to measure rapid sea level changes, either confirming or ruling out the passage of a tsunami.

Detailed Network Maps

Interactive graphical image-map of New Zealand.

This map is a clickable key to maps showing GeoNet instrumentation sites on the NZMS 262 series map sheets (the grey zones). Greater detail is provided for the volcano monitoring networks and the regional networks (the pale blue zones).

Each site symbol is annotated with its unique site code, except where the instrument density is too great. The site code may be used to obtain further information about the location and its instrumentation from GeoNet's DELTA database.

All maps are updated regularly each day.
