A swarm of small, relatively deep, earthquakes lasting two days occurred east of Ruapehu early last week. However, there have been no significant changes to the volcano observed following the earthquakes. Te Wai ā-moe (Ruapehu Crater Lake) temperature remains stable at about 12°C. We continue to record emissions of volcanic gas indicating heat and gas flow from depth is occurring. The Volcanic Alert Level remains at 1 and the Aviation Colour Code at Green.
Based on observations from a recent observation flight, webcam and satellite imagery, we can confirm no further ash emissions have been detected at Whakaari/White Island. Emissions are limited to steam and gas emissions. The Volcanic Alert Level remains at level 2 and the Aviation Colour Code remains Yellow.
The top of the South Island sits waterlogged after many days of heavy rainfall. With more rain forecast we’re seeing a situation evolving where landslides may occur with little to no warning. We’ve pulled together info from the experts to make sure you can get prepared.
Welcome, haere mai to another GeoNet Data Blog. Today’s blog is about some new data we recently started collecting at Te Wai ā-moe, Ruapehu Crater Lake.

When people hear the word “tsunami”, they often picture a single towering wave crashing onto the shore, but a tsunami is far more complex – and far more dangerous. And we need to be prepared for them.
After a large earthquake, our team provide fast and accurate information to support emergency managers and decision makers so they can support communities impacted by the earthquake shaking. However large quakes are only a part of our monitoring efforts. In the background we keep a close eye on many small and often unfelt earthquakes which help us understand stress within the Earth’s crust and how we can all be better prepared for the large ones.
Based on observations in recent weeks, including webcam and satellite imagery, no further ash emissions have been detected at Whakaari/White Island. The Volcanic Alert Level is lowered to 2 and the Aviation Colour Code to Yellow.
We’ve been tracking a slow-slip event (or ‘silent’ earthquake) in the Hawke's Bay region since the beginning of May. Our instruments have measured approximately 2 cm of eastward motion over the past two weeks. To put this in perspective, 2 cm represents approximately six months worth of plate motion in only two weeks.
The emission of steam, gas and minor amounts of volcanic ash continues at Whakaari/ White Island but appears to be declining. While significant steam and gas plumes continue to be observed from the Bay of Plenty coast, no major ash emission have been detected from the land or satellite data over the past two weeks. The Volcanic Alert Level remains at 3 for now (minor volcanic eruption) and the Aviation Colour Code at Orange.
