Whakaari/White Island remains in an elevated state of volcanic unrest. Gas flux has varied above background levels, and was elevated in our latest observation flight. Other monitoring parameters mostly remain within the range observed over the last 2 months. The Volcanic Alert Level remains at Level 2; Aviation Colour Code remains at Yellow.
On Monday 25 May a strong M5.8 earthquake occurred 30km north-west of Levin. This was followed by hundreds of aftershocks, including a M5.2 on Tuesday 26 May 2020.
After a recent heating cycle, we anticipated that Crater Lake (Te Wai ā-moe) would begin cooling to lower temperatures seen earlier this year. The lake reached a peak temperature of 42°C in early April and cooled to around 35°C shortly after. Recent monitoring indicates continuous gas flux which has kept the temperature around 35°C through May.

In earlier articles, we let you know how we are monitoring New Zealand’s geohazards through the COVID-19 pandemic. Here, we’re sharing a bit more about how we’re keeping an eye on earthquakes around the country.
An expected cooling trend for Crater Lake (Te Wai ā-moe) is now confirmed. The lake reached a peak temperature of 42°C in early April, and is currently at 35°C.
So how do you monitor a volcano if you don't physically go there?
Whakaari/White Island remains in an elevated state of unrest. No significant changes in the amount of volcanic gas emitted or seismic activity were recorded in March-April. The Volcanic Alert Level remains at Level 2; Aviation Colour Code remains at Yellow.
On Friday 27 March, the friendly, bearded face of Ken Gledhill had his last day at GNS Science (well technically he was at home in his bubble!). Ken has been at GNS for 38 years, 12 of those as the Director of GeoNet, and 4 as the GeoNet Network Manager.
The Auckland Volcano Seismic Network has detected the slowdown of Auckland city in response to the COVID-19 lock down. The seismic noise is at levels usually seen on a Sunday, just one of the interesting signals we can see from our seismic data.
