New Zealand to fund volcano monitoring improvements in Vanuatu 6 March 2012

Vanuatu has plenty of volcanic activity: Ambrym, Aoba, Gaua, Yasur are perhaps the best-known of the archipelago’s historically active volcanoes, all of which have produced violent and disruptive eruptions in the past, and have plenty of destructive potential for the future.

The news that Vanautu’s volcano monitoring capacity is to be enhanced in a five-year programme with the help from New Zealand is therefore very welcome. The New Zealand Government’s aid agency is providing NZ$500,000 for real-time seismic and camera monitoring of Ambae (Aoba), Gaua and Tanna (Yasur) volcanoes. A programme of community outreach and education, technical training and volcanic emergency response plan development is also being supported in a partnership between GNS Science in New Zealand and the Vanuatu Meteorology and Geohazards Department.

The Smithsonian Institution and United States Geological Survey Weekly Volcanic Activity Report, compiled by Sally Kuhn Sennert, has been issued for the week 1-7 June 2011. It’s been a lively volcanic week – highlights include:

  • Dieng Volcanic Complex: carbon dioxide emissions and seismicity both remain elevated
  • Popocatépetl: ash plumes reaching altitudes between 1 and 3 km create ashfall in nearby regions
  • Puyehue-Cordón Caulle: an eruption began on 4 June following intense seismicity
  • Kilaeua: two lava lakes were active during 1-7 June

Vanuatu: alert level raised for Yasur 3 June 2011

Yasur volcano, 24 February 2009. Picture by Verity Borthwick (reproduced under Creative Commons licence).

The stratovolcano Yasur on Tanna Island in Vanuatu is highly active: the Global Volcanism Program notes that Yasur has ‘been in more-or-less continuous strombolian and vulcanian activity since Captain Cook observed ash eruptions in 1774’. Cook himself compared the volcano to Stromboli because of its continuous lava fountaining. Yasur is also highly accessible, and is one of Vanuatu’s most important tourist attractions.

Early last month satellite sensing revealed strong degassing from Yasur, and local residents reported strong explosions. The hazard level for Yasur was then at 2 (on a scale of 0-4, where 4 is the highest). In bulletin no. 1, issued on 12 May, the Vanuatu Geohazards Observatory noted that this strength of degassing ‘is not common for this volcano’ , possibly indicating ‘magma intrusion in the volcano conduit’, and warned of further potential explosive activity. The bulletin described the then level of activity at Yasur as ‘a minor eruption phase with persistent strong explosions that could be heard and felt’.

A geohazards team from the Vanuatu Geohazards Observatory carried out further assessments on 31 May and 1 June. In its bulletin no. 2 of 1 June 2011 the Observatory reports a ‘moderate to large eruption’ of Yasur under way with ‘strong explosions and ash bombs/emissions from all three active vents’. The hazard level has therefore been increased with effect from 1 June to level 3. Access to Yasur has been closed, with a 500-metre-radius exclusion zone in place around the volcano.

Continuing Gaua activity at the NASA Earth Observatory 27 April 2010

Eruption of Gaua Volcano, 24 April 2010 (NASA ALI/EO-1 image)

As reported here last week, activity is continuing at Gaua volcano in Vanuatu, with the government planning for evacuations of Gaua Island. The NASA Earth Observatory has been providing some excellent satellite imagery of Gaua, most recently the above image, captured on 24 April 2010 by the Advanced Land Imager aboard NASA’s Earth Observing-1 (EO-1) satellite. The brown areas on the left of the image, to the west and south-west of the volcano, show where volcanic emissions and ashfall have damaged and killed vegetation.

The world is paying little attention to the activity at Gaua, but it is shaping up to be a very nasty, hazardous and disruptive eruption. Ashfall, poisonous gases, volcanic bombs and mudflows are being produced by the active cone, Mount Garet, and emissions are tainting local crops and water supplies. Rising water levels in the crater have been reported, increasing the risk of still more dangerous mudflows. The population of Gaua has already had to abandon the western side of the island and seek refuge in the east, away from the worst of the volcano’s ash and fumes, but as the activity increases they may have to evacuate completely. Radio Australia News quotes Vanuatu Geohazards Technical Advisor: ‘The current risk is mainly ash falls and then mudflows. It’s true that we have an increase in activity but not like a level 3. Evacuation is ready the plan is ready the location is ready, it’s a very tough situation for the local population of Gaua, they’re scared they’re afraid, it’s a very new situation for them’.

The alert level for Gaua is still at level 2, according to the Vanuatu Geohazards Observatory.
