This weekend's earthquakes were within the expected behavior for the 2010 Canterbury aftershock sequence.


Our shaking images help you select the appropriate shaking level when completing an earthquake felt report. We are giving these illustrations a refresh and would love your feedback on what we have come up with.


The unusual volcanic earthquakes under Mt Ruapehu have considerably reduced in number. The Crater Lake continues to show a slow decline in lake temperature, and water level indicates minor overflows. The volcanic gas monitoring continues to measure low-moderate volcanic gas emissions. The Volcanic Alert Level remains at 1 and the Aviation Colour Code at Green.


No clear eruptive activity has been observed at Whakaari/White Island since Saturday 25 May. We have conducted further gas and observation flights and measured an elevated magmatic gas output. The Volcanic Alert Level remains at Level 2 (moderate to heightened unrest) and the Aviation Colour Code remains Yellow.


Welcome, haere mai to another GeoNet data blog. Today, we look at the seismic structural array monitoring programme – possibly something you’ve not heard of before, and we answer some frequently asked questions.


Due to the absence of further eruptive activity at Whakaari/White Island since Saturday 25 May, we have lowered the Volcanic Alert Level to Level 2 (moderate to heightened unrest) and the Aviation Colour Code to Yellow.


Since, Friday 24 May we have observed three gas-driven eruptions at Whakaari/White Island. We take a closer look at what has happened and what may happen next.


With the views that we have available, we have not been able to detect any further eruptive activity at Whakaari/White Island. We are intermittently seeing the more typical steam and gas emissions when views are clear. However, we can't rule out unobserved eruptive activity, so the Volcanic Alert Level remains at 3 and the Aviation Colour Code at Orange.


Minor volcanic eruptive activity continues intermittently at Whakaari/White Island. Volcanic Alert Level remains at Level 3 and Aviation Colour Code remains at Orange.


Another minor eruption occurred at Whakaari/White Island at approximately 08:10 am NZST today (May 25). The Volcanic Alert Level has been raised to Level 3 and the Aviation Colour Code changed to Orange.
