National earthquake monitoring agency GeoNet has confirmed that a faster website it has been trialling will fully replace its old system in September.
GeoNet Rapid, which publishes earthquake size, strength and location up to 10 times faster than the agency's old site, has been on trial since March.
GeoNet data centre manager Kevin Fenaughty says the site publishes information within two minutes of an earthquake and doesn't require a seismologist to interpret it.
He says that at present the GeoNet sends text messages to civil defence and other emergency response groups within about 15-20 minutes of an earthquake and under the new system the messages will go out in about one or two minutes.
Mr Fenaughty says there have been no technical problems with the new site and plenty of people have been visiting it, along with more than 12,000 people downloading the mobile phone application.
