Perhaps we can take our thoughts to dampen the effect ...

There is a sleeping super volcano in Europe, and it isn't in Italy (a country famous for its eruptions). This giant is located under the Laacher See, a caldera lake in Germany, and it is showing signs of life. Should it erupt, it could spew billions of tons of magma as far as 620 square miles. Update inside.

Editor's Note: As pointed out in the comments below, Laacher See's volcano is probably not the threat it's perceived to be. Erik Klemetti called the news spread by the Daily Mail "fearmongering" and went on to debunk it in his Wired article here. It's definitely worth a read. Our original article follows, but it's best read with Klemetti's clarifications in mind.

The Laacher See volcano is thought to erupt every 12,000 years or so, and it last went off 12,900 years ago. It's been giving scientists subtle hints: some seismic tremors recorded in the region in February, and the somewhat disturbing release of carbon dioxide bubbles into the lake. This bubbling is referred to as "de-gassing," which comes from the magma chamber.

What could happen if the sleeping giant decides to blow? The Lacher See volcano is believed to be the size of the Philippines' Mt. Pinatubo that erupted in 1991 and was the biggest eruption of the 20th century.

Mt. Pinatubo ejected 10 billion tons of magma, 20 billion tons of sulphur dioxide and nearly four cubic miles of ash, and caused a 0.5 Celsius drop in global temperatures. So remember that Icelandic quake that disrupted travel for a few weeks? You can forget that. Think bigger.

Scientists say the last time the Lacher See erupted, it covered 620 square miles of land with ash and rocks and the remnants can be found all around Europe today. At the very least with a new eruption there would be mass destruction and an ash cloud that could cause short term global cooling.

So what should Europe do to prepare? Scientists are taking a wait and see attitude as they closely monitor the signs of life under the lake. With today's technology hopefully there would be ample warning before a catastrophic eruption to avoid widespread loss of life.

It may be helpful, however, to review the do's and don'ts learned when Pompeii erupted to make sure there are viable escape plans. Here's hoping today's technology gives us an advantage!

Fresh activity near a dormant 'super volcano' in Germany has left experts worried about a possible eruption. Britain's Daily Mail wrote the eruption from the 'monster' underneath Laacher See lake near Bonn, could eject billions of tons of magma which in turn could cause widespead devastation in Europe and even 'short-term global cooling'. The mountain last erupted 12,900 years ago. Volcanologists have estimated the mountain's size to be similar to that of Mount Pinatubo in the Philippines - responsible for the biggest ejection of the 20th century. Pinatubo threw up '10 billion tons of magma, 20 billion tons of sulphur dioxide 16 cubic kilometres of ash and caused a 0.5C drop in global temperatures'. Experts near the Laacher See site have detected carbon dioxide bubbles on the lake's surface and believe the mountain in Germany could be active again.

As addition to Vikings post:

"Fearmongering Gets Started in 2012: Laacher See is Not “Ready to Blow”

A quick post today about a tremendously terrible “article” in the Daily Mail this morning. The headline reads “Is a super-volcano just 390 miles from London ready to blow?” It is, of course, referring to the Laacher See in western Germany – a caldera volcano that had a large eruption 12,900 years ago that covered a significant area of Europe with ash and tephra. Surely impressive considering how few people know about the caldera volcanism in central Europe.

The article in the Daily Mail is about as substance free as you can produce – it starts off with the usual doom claptrap: “a sleeping super-volcano in Germany is showing worrying signs of waking up.” Now, you have to look carefully for what their supposed signs are – all two of them.

” This monster erupts every 10 to 12,000 years and last went off 12,900 years ago, so it could blow at any time.” No source for this recurrence interval and we all know that using poorly constrained recurrence intervals like we have at Laacher See is no way to say a volcano is (ugh) “due for an eruption”.
“Volcanologists believe that the Laacher See volcano is still active as carbon dioxide is bubbling up to the lake’s surface, which indicates that the magma chamber below is ‘degassing’.” Which, of course, Laacher See has been doing for centuries. There are stories of monks dying from asphyxiation due to carbon dioxide hundreds of years ago. I personally saw carbon dioxide bubbling when I was at the Laacher See 5 years ago (see below). Sure, it is a sign that magma is degassing, but magma passively degases all the time and is by no means, when presented as the only evidence, a sign of a volcano being “ready to blow”. I love how the video at the bottom says that it “claims to show carbon dioxide bubbling in the lake in November 2011“. Stunning considering you can go there anytime and see it (see below).

And honestly, there is no more substance to the article beyond this – no source, no named “experts”, nothing. So, the Daily Mail decided to run with a article proclaiming the imminent danger of the Laacher See based on it being supposedly “overdue” and that there are carbon dioxide seeps in the lake, something that have been there for hundreds if not thousands of years. This is the volcanic equivalent of the Daily Mail going out and saying “Massive hurricane to hit London?” because they looked out the window and saw a cloud. Irresponsible, lazy journalism at its finest.

The problem is that this kind of poor reporting with no sources spirals in today’s internet media age. Another article today purports that “fresh activity near a dormant ’super volcano’ in Germany has left experts worried about a possible eruption.” The source? The Daily Mail article. I’m sure by the end of the day that more or more “news” sites and discussion boards will be citing the Daily Mail article as proof of the impending doom from Laacher See.

This is clearly pandering to the 2012 Apocalypse crowd – we’re going to be seeing article after article about all the calamities that might befall the Earth during this year based on no scientific evidence whatsoever. Let me repeat that: There is NO scientific evidence for a “doomsday” in 2012. None. Sorry folks, look elsewhere and stop buying into this tripe. In the meantime, we’ll try not to drown in the sea about terrible media reporting."
