Welcome, haere mai to another GeoNet Data Blog. Today’s blog is a little bit different. GNS Science’s NZ Active Faults Database (NZAFD) is not a GeoNet data product but if you like earthquake data as much as we do, you will likely find this dataset a useful tool to use in tandem with our earthquake products.
Eruption may be declining at Whakaari/White Island but gas and ash emissions remain variable. Volcanic Alert Level remains at Level 3 and Aviation Colour Code at Orange.
Observations from an overflight, images from GeoNet cameras and satellite imagery combined, suggest that minor eruptive activity Whakaari/White Island may be declining. Minor ash emission does continue but seemingly at lower levels than in the past few weeks.
What is the Average?
Welcome, haere mai to another GeoNet Data Blog. Today’s blog is about averages. We look at volcanic gas emission rates and see why some average values might be better than others.
Low level eruption continues with variable gas and ash emissions at Whakaari/White Island. Volcanic Alert Level remains at Level 3 and Aviation Colour Code at Orange.
Images from GeoNet cameras and satellite imagery combined with data from gas-measurement flights on the 5th and 11th of September 2024, confirm that minor eruptive activity Whakaari/White Island continues.
GeoNet is a web of science, technology and people that collects many of Aotearoa New Zealand’s land and geohazard datasets which contribute to how we understand our land. A key part of this sees the GeoNet programme collect comprehensive data while monitoring the geological hazards our country faces including earthquakes, volcanoes, large landslides, and tsunami.
Minor volcanic unrest continues at Mt Ruapehu as lake cools. Volcanic Alert Level remains at 1.
Over the last six months at Ruapehu, Te Wai ā-moe (Crater Lake) has slowly cooled from 31 °C to 11 °C. Our 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.
Rapidly advancing science gives our volcano team a wide range of remote monitoring tools to keep a close eye on our active volcanoes. The data from these tools helps us provide valuable information to responding agencies, infrastructure providers and the public, to support disaster management and building community resilience.
Minor eruptive activity continues at Whakaari: volcanic ash emissions continue. Volcanic Alert Level remains at Level 3 and Aviation Colour Code remains at Orange.
An observation flight on Wednesday 21 Aug 2024 and ongoing satellite imagery confirms that minor eruptive activity Whakaari/White Island continues from the new vent that became active in early August. Satellite data further suggests that SO2 levels remain high. The amount of volcanic ash in the plume has not changed much over the last week. There remains a very low likelihood of ash falling on the ground on the mainland.
Webcam Images – Another Look
Welcome, haere mai to another GeoNet Data Blog. Today we are going to take another look at our webcam images, focusing on Whakaari/White Island.
GNS scientists are actively monitoring Whakaari/White Island which sits 48km offshore from Whakatane and has been at Volcanic Alert Level 3 since 9 August. Read on for the latest news, and answers to some frequently asked questions.
