Raoul Island, home to our northernmost tsunami gauge site, recently had a visit from three staff in our Remote Infrastructure Management team. The team travelled to Raoul in June to repair a damaged coastal tsunami gauge and undertake some much-needed maintenance work.
Despite intermittent gas pulses, volcanic gas emissions have declined. Volcanic tremor remains low, while the Crater Lake temperature has recovered slightly to 25 °C. The Volcanic Alert Level remains at Level 2.
Recent monitoring data, including flights to make visual observations and measure gas emissions, confirm volcanic unrest remains at low level at Whakaari/White Island. The Volcanic Alert Level for Whakaari/White Island remains at Level 1. The Aviation Colour Code also remains at Green.
A brief period of strong volcanic tremor was recorded over the weekend and Crater Lake temperature has stabilised. The Volcanic Alert Level remains at Level 2.
Volcanic tremor remains weak and lake temperature continues to decline. The Volcanic Alert Level remains at Level 2.
GNS Science Senior Volcanologist Geoff Kilgour gives an update on current volcanic activity at Mt Ruapehu, and what data the team are hoping to collect soon.
The level of volcanic unrest at Mt Ruapehu has decreased from heightened to moderate, however the potential for eruptions remains. The Volcanic Alert Level remains at Level 2.
Volcanic tremor levels were moderate last week, and the Crater Lake (Te Wai ā-moe) temperature has been steady around 31 °C. However, volcanic unrest continues at Mt Ruapehu and the potential for eruptive activity remains. The Volcanic Alert Level remains at 2.
Welcome, haere mai to our first GeoNet Data Blog post! This is a new initiative with a focus on GeoNet data-related stories. In some blogs, we plan to talk about specific data sets, and in others more general data information. We’ll try not to make the blogs too technical, but we will sometimes include some computer code to help some readers work with the data sets.
Gas emissions are still elevated at Mt Ruapehu. The Crater Lake (Te Wai ā-moe) temperature has declined over the past week. Volcanic tremor levels have generally declined but remain variable. Volcanic unrest continues at Mt Ruapehu and the potential for eruptive activity remains. The Volcanic Alert Level remains at 2.
