Katla volcano in Iceland ‘set to erupt in explosion that will dwarf devastating 2010 ash cloud’, scientists claim

Is the headline of the Sun this evening. The Katla Volcano is a subglacial volcano meaning if it blows it is likely to cause substantial disruption to European air travel. The volcano is currently on a yellow alert due to volcanic unrest.

Huge swarm of earthquakes in Iceland between Reykjanes and Krysuvik volcanos could suggest an iminant volcano eruption, as if we hadn't had enough to worry about.

Cant be as bad as the one we had a few years back can it. Difference this time if it is a big one,there is not much flying at the moment. If it is a big eruption then lets have it sooner rather than later.

So the current swarm activity is around the Iceland capital Reykjavik itself. Potentially very dangerous times ahead for Iceland but at this stage it's still unclear if the large number of earthquakes are being caused by the movement of magma.

The Icelandic earthquake swarm is a further threat to Icelandic aviation although unlike some other volcanos on Iceland, the volcanos nearest to the earthquake swarm aren't covered by glaciers. The problem in this particular instance is the swarms proximity to the Iceland Capital Reykjavik with a population of 123,000 people is only 10 miles away.

The airport is situated around 13 miles North West of the volcano so if the volcano blows it will be rendered unusable to air traffic.

Definitely one to keep an eye on over the coming weeks.

Edited to improve post accuracy.

Over the last 24 hours it has been confirmed lava is moving into the magma chamber and a volcanic eruption at Iceland's Krýsuvík volcano is now reported as imminent.

If it does erupt it wonders how the size of ash cloud it will be. Went out in the car this morning and it was covered in Sahara dust,nothing is ever said about that any time. I live south of Bristol.

That all depends on the size of the eruption.

Historically, previous eruptions for this volcano are thought to have been mostly between VEI 1 and 3 so hopefully not a risk to aviation beyond Iceland itself although a huge risk for Reykjavik.

La Parma volcano is on yellow alert because of volcanic unrest.
Once again La Palma volcano is on Yellow alert due to seismic unrest.

La Palma is a shield volcano and whilst it poses no immediate threat to aviation, the volcano is considered a significant threat due to a fault line running through the centre of the island. It is widely thought the volcano has the potential to collapse into the Atlantic Ocean causing a Tsunami.

Reading the post by the Boss above, I think of Krakatoa the Indonesian island that was obliterated by an explosive eruption and created the loudest recorded sound and the tsunami. But wait a moment, Krakatoa has re emerged and currently exists and is active suggesting that a volcano never dies but reforms.

Geography is a fascinating subject, at least to me! So varied, not just limited to countries and their capitals.

Very frustrating when watching quiz shows (The Chase, Tipping Point) and a contestant says "I'm no good at geography". Know someone who's travelled extensively around the UK, in a motorhome and that's her standard comment. "Lots of pretty places but can't tell you where they are" was another comment.

My point exactly. Geography encompasses Anthropology, Earth Sciences and much more, a fascinating subject that in my case included religions.

I have undertaken a study of Ecclesiastical Law and is itself a fascinating subject.

As I mentioned previously this volcano doesn't pose a risk as such to aviation but it is regarded as a potentially deadly volcano due to the relatively high risk of the island falling into the sea causing a catastrophic Tsunami.

I totally agree, Geography is a fascinating and informative subject. A little while back, I was watching a YouTube video (I think it was comparing UK and US education) and an American student asked why we studied geography. Her view was that it was only maps and cities. It's so much more. Rock formation and weathering, ocean currents and weather patterns, plate tectonics, vulcanism and mineral deposits to name but a few.
Some years back, my then girlfriend and I went on holiday to Arizona. We had a transit via HOU and as we were in the descent, there was the most incredible view of Oxbow Lakes (my geography lessons came flooding back to me - I only studied to 'O' level, but I did pass). On the same flight, the lady sitting next to me and my girlfriend, turned out to be a US Travel Agent. When She asked where we were going she said Arizona was boring why go there? Anyone that has visited The Grand Canyon, Monument Valley and The Painted Desert will know that Arizona is anything but boring.
Getting back on topic, regarding the possible Tsunami, is this the one that has had experts worried for years that it will hit the East coast of the US including New York?
