National Advisory: MCDEM Cancellation Message

National Advisory – MCDEM Cancellation Message

The threat related to the eruption at Tongariro Te Maari crater that occurred yesterday (21 November, at 1:25pm) has now passed. We are therefore cancelling the National Advisory that related to that eruption.

However, GNS Science indicates that there remains a significant probability of sudden eruption within the next week. Should a further eruption occur MCDEM will issue a new National Advisory or Warning.

Volcanic Alert Bulletin:

The latest GNS Science Volcanic Alert Bulletin information is as follows:
Activity decreased at Tongariro but risk remains high.

Activity at Tongariro has been at low level since yesterday’s eruption. The Volcanic Alert Level remains at 2 and the Aviation Colour Code at Orange.

There remains a significant probability of sudden eruption within the next week.

After reviewing monitoring data, videos and images for yesterday's eruption at Tongariro, GNS Science confirms that the eruption lasted approx 5 min, with an ash column and plume being ejected 3-4 km above the Upper Te Maari crater.

The eruption was recorded by GeoNet’s webcam and a video of the eruption can be found on the GeoNetNZ channel at the following URL: http://www.youtube.com/watch?v=X2ASNu7vVGA

An inspection flight will be made later today and GNS Science continues to closely monitor the situation.
Background:

The point of origin of yesterday’s eruption was similar to that from August 6, 2012. During yesterday’s eruption, two small pyroclastic density currents were produced at the base of the column, to the West and North of the crater, and reached a limited distance of a few hundred meters downslope. These pyroclastic density currents are a mixture of ash,volcanic gas and atmospheric air flowing horizontally and being driven by gravity. Scientists believe that these were produced by part of the ash column not being energetic enough to rise, causing it to collapsing at the base and flow downhill. There is no evidence at this stage of big blocks having been ejected far from the crater during the eruption.

From the preliminary examination of ash, GNS volcanologist Michael Rosenberg reported that “we haven't found any evidence yet of magma having reached the surface during the eruption”. More ash sampling and analyses by New Zealand volcanologists are planned or already underway.

There was no observed warning immeditately prior to yesterday’s eruption. Future eruptions could also occur with little or no warning.

Aviation Colour Codes are based on four colours and are intended for quick reference only in the international civil aviation community. Code Orange indicates that a volcanic eruption is underway but with little or no ash being produced.

The Volcanic Alert Level ranges from 0 to 5 and defines the current status at a volcano.

Level 2 indicates that a minor eruption has occurred.

Pacific Spying: Mass Surveillance Of NZers Confirmed By Former GCSB Director - Contradicting PM John Key

Scoop Editor Alastair Thompson Reports: Yesterday morning former GCSB Director Sir Bruce Ferguson confirmed mass surveillance of New Zealnders in the Pacific is taking place as revealed in the latest Snowden leaks investigated by Nicky Hager. In 2013 John Key told press gallery reporters that in the event mass surveillance was found have been conducted by the GCSB, he and the director of the GCSB - his childhood friend Ian Fletcher - would resign. As the controversy deepens a year and half later Fletcher has already resigned. But will Key? More>>

Gordon Campbell: Legal Fudging Of The GCSB Revelations

As many have noted, the Hager/Snowden revelations of the spying by our security agencies on our Pacific neighbours and allies is a virtual re-run of the pre-election debate. It is a situation where the government (a) stonewalls, (b) baldly asserts that mass surveillance is not occurring despite the Snowden evidence that it is, and (c) claims that the GCSB actions were lawful. Yet as Greens Co-Leader Russel Norman says, this can be true only if the legislation passed last year by the Key government has made the mass surveillance of New Zealanders – and the related handing over of their private data to the NSA – lawful.
