Scientists here have started using a sensor system to estimate the extent and location of earthquakes before they hit.
The FinDer sensor system has provided good results when used in real-time in recent magnitude 6 earthquakes around Porangahau and Geraldine.
The technology detects "P-waves" before the more damaging "S-waves" arrive soon after.
Some android phone users already get warnings via a Google system.
But New Zealand does not have an official earthquake early warning system as exists in other countries like Japan.
