Possible eruption at Bárðarbunga

VolcanoCafé

The almost obscenely inconspicious volcano of Bárdarbunga seen in all it's icy glory. The almost obscenely inconspicious volcano of Bárdarbunga seen in all it’s icy glory.

First of all let me say this, it is only IMO and Almannavarnadeild ríkislögreglustjóra that has the authority to officially declare an eruption in Iceland and issue warnings. Untill they have officially released a warning for an eruption there has been no confirmation.

That being said, below follows what I think is happening currently at Bárðarbunga.

Official warnings

There has so far just been two warnings issued and that is for a potential Jökulhlaup and about a magmatic intrusion. If a medium to large eruption takes place a large Jökulhlaup could burst out and inundate land around the rivers and could be a potential danger to the locals. Here are the warnings issued by Almannavarnadeild ríkislögreglustjóra:

“The National Commissioner of Police and the District Commissioner of Police at Hvolsvöllur and Húsavík have declared a Civil Protection Uncertainty…

On punishment of young scientists

VolcanoCafé

Giordano Bruno made the ultimate sacrifice for science at Campo dei Fiori. Giordano Bruno made the ultimate sacrifice for science at Campo dei Fiori.

On the 17th of February 1600 Giordano Bruno was burned at the stake for heresy. His mouth had been tied shut, denying him the possibility to speak out. His crime was that, as a scientist, mathematician and philosopher, he had dared to say that the stars in the heavens were actually suns with planets, and that those planets also carried intelligent life. He also claimed that the intelligent life on those planets were God’s creatures as well as humans.

Galileo Galilei was condemned as guilty of heresy on the 22nd of June 1633 for daring to claim that he had proof that the earth indeed circled the sun. His sentence was house arrest for the rest of his life.

One would think that persecution of science and scientists were a thing of the past, at least…

Grimstone vs Yellowvötn: Battle of the Giants

The importance of perspective. There’s only hope that one day nihil-hubrists will fully realize their fully of declaring impending doom after every minute geologic event in Yellowstone

In the west corner of the ring you find Yellowstone wearing blue, red and white striped trunks and in the east corner you find Grimsvötn wearing Fire & Ice colored trunks. Welcome to a spectacular fight about who is the largest, meanest volcano on the block. As the fighters are squaring off we eagerly await for the first blow from this formidable match, and there it came, it is a stunning early knock and we have a countdown to ten. The new world champion is surprisingly Grimsvötn…

I read everything that Erik Klemetti writes and have been a big fan of his since he started the concept of volcano blogging. This week he wrote a splendid article on Yellowstone (link below) based on a paper by Jamie Farrel et al…

Earthquake prediction at the South Icelandic Fracture Zone

An interesting read that gives a glimpse into the frustrations of seismology

Volumetric strainmeters are used around the Globe to try to predict earthquakes. One of the main reasons for the proliferation of them is to be found in Iceland. Before we go to the latest events in the Southern Icelandic Fracture Zone (SIFZ) we should start with the classic example from prior to the M6.6 earthquake on the 17th of June in 2000.

The spike above is known in its highly scientific term as the “Big Bump”, it was recorded as starting on the 28th of May and ended on the 1st of June. It is believed to have been caused by a pocket of fluids being squashed upwards by the mounting strain at the fault line. Notice that the big bump lowered…

Editorial on our April fool’s Joke

Pretty much all of the US has by now noticed our small little April fool’s joke. Why now you might ask? Well, let us start at the beginning.

The readers and commentators at Volcanocafé are as a crowd a highly intelligent and very knowledgeable group. Since the onset of Volcanocafé we have published a bogus report on some extremely unlikely volcano that either is about to erupt, or is erupting, every April first. The only problem is that our readers are so fantastic that we have to place the level high to fool them for even a split second.

As such this year’s Aprils joke was a failure. It took about a minute for our regular readers to see through the joke. There was also a hidden clue in the piece that anyone…

The Road to Sinabung

VolcanoCafé

We often have a tendency to believe that an eruption will come quickly after seeing an intrusion take place. Of course this is normally not the case, something that Sinabung has proven quite well. As the local Indonesian authorities are starting to issue warnings that Sinabung might be getting closer to a major eruption I thought we should take time to look at what has gone on for the last few years, and what a “major eruption” might entail at Sinabung.

Background

Mount Sinabung is situated about 40 kilometers from the Toba system, and even if it feeds from the same deep magmatic source it does not share the same magmatic reservoir as its grander neighbor. The location at the Sunda Arc tends to give sticky magma with a capacity to build up pressure in the system, that withstanding, most eruptions from the nearby volcanoes are not big. Previously Sinabung…
