Volcanic Risk Forum makes headlines (September 2013)
The sixth annual Auckland Council CDEMG-DEVORA Forum on Friday, 27 September was covered by numerous print and television media outlets:
- Auckland the most unprepared for a disaster (Stuff, 27/09/2013)
- Eruptions on the agenda (Stuff, 26/09/2013)
- Hon. Nikki Kaye Speech: Managing Volcanic Risk in Auckland (Scoop, 27/09/2013)
- Aucklanders warned about risk of volcanic eruptions (NZ Herald, 27/09/2013)
- Aucklanders warned of volcanic risk (Otago Daily Times, 27/09/2013)
Predicting big natural events (May 2013)
The two felt earthquakes in March prompted the public to wonder if they were related to the AVF. CDEMG Controller and DEVORA Steering Committee member Clive Manley was featured in an article about earthquakes and volcanoes in Auckland. Clive described some of the research taking place through DEVORA.
DEVORA researchers Dr Darren Gravley (University of Canterbury) and Elaine Smid (University of Auckland) were interviewed about using ground penetrating radar on destructive volcanic flow (called a ‘base surge’) deposits from Auckland’s volcanoes. The technique will help us identify potential impacts from base surges in future eruptions.
Prolonged activity at Rangitoto? (April 2013)
In 2009, DEVORA MSc student Andrew Needham discovered that Rangitoto Volcano had erupted twice —once about 600 years ago, and then again 50 years later, about 550 years ago. Now, the discovery of minute layers of ash found in a core from Lake Pupuke indicates that it may have erupted several times earlier. For more information, check out the press describing the research article:
- Auckland eruptions ‘could go on for long time’ (Radio NZ, 11/04/2013)
- Rangitoto erupted semi-continuously (NewsTalk ZB, 11/04/2013)
- Rangitoto erupted frequently from about 1500 years ago to 500 years ago and wasn’t just formed 500 to 550 years ago, say Auckland University scientists (NZ City, 11/04/2013)
- Auckland eruptions could last longer (TVNZ, 11/04/2013)
- Rangitoto research prompts rethink of Auckland volcanoes(Voxy, 11/04/2013)
- New volcano research prompts re-think (NZ Herald, 11/04/2013)
- Rangitoto ‘could blow again’ (Stuff, 11/04/2013)
Auckland earthquakes generate interest in the Auckland Volcanic Field (March 2013)
The earthquakes in Auckland on Sunday, 17 March sparked interest in other natural hazards that could occur in Auckland, such as a volcanic eruption. DEVORA researchers Dr Jan Lindsay and Darren Gravley were interviewed about the effect of an eruption on Auckland.
- Is Auckland ready for a natural disaster? (New Zealand Herald, 29/03/2013)
- Dr Jan Lindsay describes how underground monitoring and careful logging of borehole data are scientists’ best predictor of future volcanic behaviour in Auckland (New Zealand Herald, 28/03/2013).
Professor Shane Cronin was interviewed for a feature on Auckland’s volcanoes for TVNZ’s Close Up programme. The programme also featured interviews with Clive Manley, Auckland Council’s CDEM Controller and DEVORA Steering Committee member (Auckland Volcanoes feature starts at 8mins 30 secs). Several news articles have highlighted research examining Auckland’s susceptibility to lava flows carried out by our partners at Massey University’s Volcanic Risk Solutions. The researchers found that in central and northern Auckland, lava would likely be channeled between ridges, while in the flat areas of southern Auckland, the flows would spread out more but not travel as far. The study cited 6.5 km as the maximum lava flow length expected in central Auckland, based on topography, building density, and previous lava flow characteristics. You can read the original article.
- Where would the lava flow in Auckland? (NZ Herald, 22/08/2012)
- 500,000 people in lava’s line of fire (NZ Herald, 23/08/12)
- Lava could extend 11 km in Auckland (NewsTalk ZB, 22/08/2012) [Note from DEVORA researchers: The study cites 6.5 km as the maximum lava flow length expected from future eruptions. The longest flow known from a previous Auckland eruption is 10-11 km, most likely from Mt St John.]
- Auckland volcano danger drowned out (Stuff, 23/08/12)
- No warning before volcanic eruption (Stuff, 23/08/12)
- Volcanic eruption could take Auckland by surprise (TVNZ One News, 23/08/12)
What does the Tongariro eruption mean for Auckland? (August 2012)
The eruptions at White Island and Mt Tongariro in early August 2012 renewed interest in the Auckland Volcanic Field. The activity in the central North Island does not affect AVF volcanism, but if ash-producing eruptions at Tongariro continue and the wind direction shifts northward, ash from Tongariro could reach Auckland. Major disruptions in aviation schedules would be expected in that case. You may read about the effects of ash fall, and how best to protect yourself and your property, here.
Many DEVORA researchers are involved in the investigations and response. An excellent compilation of several of their expert opinions can be found at Tongariro volcanic eruption and ash fall — experts respond. (Science Media Centre Blog, 7 August 2012) Clive Manley, Manager of Auckland Council’s Civil Defence and Emergency Management and member of the DEVORA Steering Committee, explained how Civil Defence takes preparation for a volcanic eruption in Auckland very seriously (TV3, 8 August 2012). Some of the expected effects of an Auckland eruption are described in this article (NZ Herald, 11 August 2012). Fortunately, no one was hurt in the Tongariro eruption. If a similar event occurred in Auckland, however, how would we fare? Various DEVORA researchers comment on Auckland’s preparedness in light of the unpredictability of volcanic eruptions (NZ Herald, 12 August, 2012). Please refer to GNS Science’s GeoNet webpages for up-to-date information regarding the Tongariro and White Island eruptions.

Lessons from Chile eruption for Auckland (June 2012)
Drs Tom Wilson (University of Canterbury) and Carol Stewart visited Chile to investigate the effects of ash from Puyehue-Cordon Caulle Volcano’s eruption in Chile over the past year. The article (Stuff, 07/06/2012) highlighted lessons for Auckland that were gleaned from their trip to the area.
New Study Revises Eruption Evacuation Radius (December 2011)
In a new study, Dr Gill Jolly and others simulated a base surge resulting from an AVF eruption. They found that the previously estimated evacuation radius of 5 km may not be enough in some instances. Read the article (Stuff, 4/12/2011). The published article may be found here (Springer, Bulletin of Volcanology, DOI: 10.1007/s00445-011-0556-y).
