Eruption possible: Öræfajökull volcano, Iceland

The Department of Civil and Emergency Management in Iceland have issued a new status for Öræfajökull volcano saying that it shows clear signs of unrest. They added that the volcano is in typical preparation stage before an eruption.

For more than 250 years Öræfajökull has been lying dormant. The volcano is covered with an ice cap which forms the southernmost part of Vatnajökull glacier. The cauldron formed last winter in the ice cap of the volcano’s crater.

The mountain stands at 2,110 m (6,921 ft) above sea-level.

If it does erupt – it has the potential to cause significant impact to aviation across the Atlantic. We all still remember Eyjafjallajökull !

Ongoing Bali volcanic threat – update

Update June 29, 2018:

Following the volcanic eruption on Jun 28 at Bali’s Mount Agung, the airport has been closed all morning today, Jun 29, and only just reopened at 1430 local time (0630z). Over 500 flights have already been cancelled as a result. Big delays expected all day and into the weekend. Further closures due to volcanic ash are still possible.

Per latest report from Darwin VAAC, there is a volcanic ash cloud observed up to FL160 in the area, but they predict winds will carry the ash southwest toward Java, Indonesia’s most densely populated island.

 


 

In Short: Continued vigilance required for operations to Bali; The alert level for Mt Agung eruption remains at 3 (on a scale of 1-4). Last ash plume on 26 March rose to at least an altitude of 11,650 ft.

When Mount Agung erupted in November 2017, airlines faced travel chaos as flights were cancelled due to the lingering ash cloud. Since then, visitor arrivals have dropped by more than 70 percent. Facing $1bn in lost tourist revenue, the Indonesian government is trying to lure tourists back to the holiday island.

The 3,000metre high volcano sits roughly 70 kilometres away from the tropical paradise’s main airport and popular tourist areas.

In a Volcano Observatory Notice for Aviation (VONA), Volcanological Survey of Indonesia (PVMBG) reported that at 1009 on 26 March an event at Agung generated an ash plume that rose at least to an altitude of 3.6 km (11,650 ft) a.s.l. and drifted NW. The Alert Level remained at 3 (on a scale of 1-4) and the exclusion zone continued at a 4-km radius.

Best up-to-date information:

The current one to watch:

Mount Sinabung – located in Medan, Indonesia is also very active at the moment (last spewing ash on Friday April 6) and may disrupt air operations to Malaysia and Singapore.

Current Aviation Color Code: RED, Eruption with volcanic ash cloud at 09:07 UTC (16:07 local). Eruption and ash emission is continuing. Ash-cloud moving to west – south. Best estimate of ash-cloud top is around 23872 FT (7460 M) above sea level, may be higher than what can be observed clearly. Source of height data: ground observer.”

We will keep an eye on this one.

Mount Sinabung roared back to life in 2010 for the first time in 400 years. After another period of inactivity it erupted once more in 2013, and has remained highly active since.

If you have travelled through the region lately and can provide members with more of an update, please get in touch. 

Guatemala’s Fuego volcano disrupts ops

An eruption at Guatemala’s Fuego volcano on 3rd June resulted in the deaths of 25 people, and forced the temporary closure of MGGT/Guatemala City Airport. After the military cleared ash from the runway, the airport re-opened on 4th June, with the warning of delays due to ongoing runway inspections.

On June 3, Guatemala’s Institute for Vulcanology (INSIVUMEH) published a map showing the volcanic ash distribution (shown on the map as the area in orange, labelled ‘Ceniza’):

Bali – Airport Status

Volcanic eruptions from Bali’s Mount Agung earlier last week forced the closure of WADD/Denpasar and WADL/Lombok airports, as volcanic ash spread across both islands.

Here’s the current situation at the airports on Dec 4:

  • WADD/Bali: Re-opened on Nov 29. (Although the airport will be closed for runway repair from 18-23z daily [except Saturdays] until Dec 31).
  • WADL/Lombok: Re-opened on Nov 30. 
  • WARR/Juanda: Open and operating. So far has not been affected at all by the volcanic ash. (Although the airport will be closed for runway repair from 16-22z daily until Jan 06).

Although Mount Agung has now stopped emitting ash, another large eruption is still likely. The local monitoring agency are registering powerful and continuous tremors, and authorities have ordered locals and journalists within 10km of the volcano to evacuate. Further intermittent airport closures are possible, depending on wind direction.

We will keep this page updated with the latest news as we get it.

Iceland Volcano alert – Katla

Icelandic volcano Katla has been raised to colour code Yellow by the Icelandic met office.

Katla lives beside Eyjafjallajökull, the volcano that closed much of Europe’s airspace for a week or so in 2010.

Colour code yellow means that there is increased activity, but no eruption … as of yet. 

volcano_status

It doesn’t mean that an eruption is ‘expected’ either, but given the proximity of Katla to the site of the major eruption in 2010, there may be correlation. Icelandic scientists have also said that an eruption of Katla is overdue.
