Tsunami Monitoring

Long period seismic sensors are in place around New Zealand to detect potential tsunami-generating earthquakes that occur off the coastline.

Tsunami gauges are also installed around the New Zealand coast. These will not provide a warning system for tsunami generated close to shore, but will confirm the occurrence of a tsunami and record the tsunami characteristics.

Check out the latest tsunami gauge recordings for operational instruments in the New Zealand region on the GeoNet website.
