2017 was marked by no eruptions from any of the active volcanoes in New Zealand; however we did see some volcanic unrest. It is not unusual for an active volcano to show signs of unrest and not follow through with an eruption.
As 2017 comes to an end, the GeoNet's volcano monitoring team recently made a series of visits to White Island, this being the last detailed assessment of New Zealand's most active volcano before the summer break.
The GeoNet tsunami gauge network recorded small tsunami waves shortly after seismic waves were generated in the Kermadec region – the cause of the seismic waves and the tsunami has been a bit mysterious but our scientists are on the case.
GeoNet runs the PositioNZ network of Continuously Operating GNSS/GPS Reference Stations on behalf of Land Information New Zealand (LINZ), and the real-time streaming of data from these stations just became a whole lot faster!
Some people feel better when we share our earthquake probabilities, others don’t and that’s okay – the important things are to be aware, understand what they mean and know what to do.
There has been a lot of attention on the Hikurangi subduction zone – we want people to be aware of the fault and know its potential for future earthquakes and tsunamis
Following Tuesday’s one year anniversary of the M7.8 Kaikōura earthquake, our scientists have a few observations about how the aftershock behaviour of the M7.8 Kaikōura and the 2010 M7.1 Darfield (Canterbury) earthquakes compare.
Metadata web app., Magma, and our old network maps are being discontinued today, but never fear - updates are here!
The latest issue of our GeoNet News magazine has been released with all the science updates a year on from Kaikōura.
The shadow of the Kaikōura earthquake and tsunami has dominated our year here at GeoNet. I feel for the many people dealing with the consequences in the region of the earthquake, from Waiau all the way up the east coast to Seddon and Ward.
