Welcome, haere mai to another GeoNet Data Blog. Today, we share some news about upcoming changes to one of the systems we use to share data with our users, https://data.geonet.org.nz (now officially renamed as our ‘GeoNet Data API’). We will tell you a bit more about the GeoNet Data API, its history, what is changing, and if you need to do something about it.
Over the past few years, we have been adapting the GeoNet sensor network to ensure it is able to meet design criteria and remains fit for purpose in the years to come. Today we look to make sure we invest in line with changing priorities and a dynamic operating environment.
Update on activity at Ruapehu: Temperature of Te Wai ā-moe (Ruapehu Crater Lake) is stable. The Volcanic Alert Level remains at 1.
The temperature of Te Wai ā-moe (Ruapehu Crater Lake) has remained relatively cool since August 2025. The current temperature is now around 18 °C. We continue to measure low to moderate volcanic sulphur dioxide (SO₂) gas emissions, and low levels of volcanic tremor. These observations are consistent with minor volcanic unrest. The Volcanic Alert Level remains at 1 and the Aviation Colour Code at Green.
How to cite GeoNet data
Welcome, haere mai to the first GeoNet Data Blog of 2026. We’re going to take a slightly different tack today and look at how to cite GeoNet data properly (and other data) and how vital it is.
We’ve collaborated with Toitū Te Whenua Land Information New Zealand (LINZ) to update the basemaps on our GeoNet website. You now have three exciting new map options to view and interact with our geohazard information.
Heavy rainfall in the Upper North Island has resulted in numerous landslides across multiple regions. Some of these landslides have had devastating impacts. Our thoughts are with everyone affected, especially where precious lives have been lost or people are missing. We also recognise ongoing efforts by our emergency response partners.
Steam and gas emissions continue at Whakaari/White Island. Volcanic Alert Level remains at 2 and Aviation Colour Code at Yellow.
Based on observations from a recent gas flight, webcam images and satellite imagery, activity continues to be dominated by steam and gas emissions at Whakaari/White Island. No recent eruptive activity has been recorded. The Volcanic Alert Level remains at 2 and the Aviation Colour Code is Yellow.
Data tutorials made easier
Welcome, haere mai to another GeoNet Data Blog. Today’s blog is about how you can use our data tutorials more easily.
Te Wai ā-moe (Ruapehu Crater Lake) is warming up. The Volcanic Alert Level remains at 1
The temperature of Te Wai ā-moe (Ruapehu Crater Lake) is slowly rising again. The current temperature is now 17 - 18 °C, from a low of 12 °C in early November. We continue to measure low to moderate volcanic sulphur dioxide (SO2) gas emissions, and low levels of volcanic tremor. The Volcanic Alert Level remains at 1 and the Aviation Colour Code at Green.
No evidence of further explosive activity at Whakaari/White Island. Volcanic Alert Level lowered to 2 and Aviation Colour Code to Yellow.
Based on observations from last week, including webcam, gas flight and satellite imagery, no further explosive activity has been recorded at Whakaari/White Island. The Volcanic Alert Level is lowered to 2 and the Aviation Colour Code to Yellow.
