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.
If seismic data is your jam, please read on. But if not, know that GeoNet is continuously improving in its data collection and processing to keep up with the changing needs of our scientific community.
Crater Lake (Te Wai ā-moe) has been heating in response to an input of hot gases and hydrothermal fluids following volcanic earthquakes beneath Mt Ruapehu in February. The lake temperature is now 40°C. GNS Science volcanologists have collected further data to understand current activity.
Have you ever filled out a felt report? Or read about how many felt reports an earthquake received, and wondered what we do with them? Well wonder no more!
• Whakaari/White Island remains in an elevated state of unrest • Amount of volcanic gas has increased slightly compared to recent measurements but remains overall on the decline • Aerial observations confirm presence of high temperature fumaroles • The Volcanic Alert Level remains at Level 2; Aviation Colour Code remains at Yellow
Crater Lake (Te Wai ā-moe) has responded to volcanic earthquakes beneath Mt Ruapehu. GNS Science volcanologists have collected data this week to further understand current activity.
A short-lived episode of volcanic earthquakes occurred beneath Mt Ruapehu last Saturday 22 – Sunday 23 February. The earthquake episode has ended.
• Whakaari/White Island remains in an elevated state of unrest • Volcanic gas fluxes are declining slightly • Aerial observations confirm presence of high temperature fumaroles • The Volcanic Alert Level remains at Level 2; Aviation Colour Code remains at Yellow
The Survey has now closed, thank you.
