After a large earthquake, our team provide fast and accurate information to support emergency managers and decision makers so they can support communities impacted by the earthquake shaking. However large quakes are only a part of our monitoring efforts. In the background we keep a close eye on many small and often unfelt earthquakes which help us understand stress within the Earth’s crust and how we can all be better prepared for the large ones.
No further detections of ash emissions at Whakaari/White Island. Volcanic Alert Level lowered to 2 and Aviation Colour Code to Yellow.
Based on observations in recent weeks, including webcam and satellite imagery, no further ash emissions have been detected at Whakaari/White Island. The Volcanic Alert Level is lowered to 2 and the Aviation Colour Code to Yellow.
We’ve been tracking a slow-slip event (or ‘silent’ earthquake) in the Hawke's Bay region since the beginning of May. Our instruments have measured approximately 2 cm of eastward motion over the past two weeks. To put this in perspective, 2 cm represents approximately six months worth of plate motion in only two weeks.
Eruptive activity declining at Whakaari/White Island. Volcanic Alert Level remains at Level 3.
The emission of steam, gas and minor amounts of volcanic ash continues at Whakaari/ White Island but appears to be declining. While significant steam and gas plumes continue to be observed from the Bay of Plenty coast, no major ash emission have been detected from the land or satellite data over the past two weeks. The Volcanic Alert Level remains at 3 for now (minor volcanic eruption) and the Aviation Colour Code at Orange.
Crater Lake cooling, minor volcanic unrest continues at Mt Ruapehu. Volcanic Alert Level remains at 1.
Ruapehu’s Crater Lake is slowly cooling and is now 17°C. Heat flux is low while sulphur dioxide gas emissions continue. The Volcanic Alert Level remains at 1 and the Aviation Colour Code at Green.
Continued minor ash emissions at Whakaari/White Island. Volcanic Alert Level remains at Level 3 and Aviation Colour Code at Orange.
The emission of steam, gas and minor amounts of volcanic ash continues at Whakaari/White Island. Ash plumes from the active vent have been ob-served during recent observation and gas flights. Due to this ongoing volcanic activity, the Volcanic Alert Level remains at Level 3 and the Aviation Colour Code at Orange.
More frequent ash emissions and occasional explosive activity at Whakaari/White Island suggest a general increase in activity. Volcanic Alert Level raised to Level 3 and Aviation Colour Code remains at Orange.
Over the past few months, volcanic ash has been identified more frequently in the Whakaari/White Island steam and gas plume. Evidence of intermittent explosive activity has also been observed during recent observation and gas flights. This gradual increase in volcanic activity leads us to raise the Volcanic Alert Level to Level 3 whereas the Aviation Colour Code remains at Orange.
In memory of FITS
Welcome, haere mai to another GeoNet Data Blog. Today’s blog is an obituary to the FITS API and database, which was turned off last week after 10 years of glorious service. Although the format is a little different from our usual blogs, we thought it an appropriate way to remember an application that provided long-standing service to GeoNet, and helped grow a culture change.
FAIR Data
Welcome, haere mai to another GeoNet Data Blog. Today’s blog is about FAIR data, what it is, why it’s important, especially to GeoNet, and what we are doing to try to make it more FAIR.
On Tuesday afternoon, 25 March, at 2:43PM we recorded at M6.8 earthquake with moderate shaking 167 km west of Rakiura Stewart Island. It was felt widely throughout the lower South Island, and generated a small tsunami.
