Flood close to Iceland volcano expected to peak today
_{Posted on03 November 2010.}
Water levels in the Gigjukvisl river in south Iceland, close to Grimsvotn volcano, have risen by about 40 cm since last night. River flow measured 1659 cubic metres just before 18:00 yesterday evening and this morning’s measurements show that the river flow is currently more than 2000 cubic metres.
Egill Axelsson, a Hydrographic specialist working at the Icelandic Met Office (Vedurstofa Islands) commented, “If this continues then we estimate that the flood will reach its peak this afternoon.”

According to mbl.is, Gunnar Gudmundsson, a geophysicist at the Icelandic Met Office said, “There was an increase in turbulence in Grimsvotn at 03:30 this morning but this has remained stable since. The turbulence has not grown in other vicinities nearby, so now it is a question of what does this mean?”
Gudmundsson added, “I am not excluding the fact that this could develop into a small volcanic eruption. However, if this does turn out to be the case, then it will be something similar to the eruption in 2004, which was not major.”
The Grimsvotn volcano eruption in November 2004 lasted for one week but no glacier burst proceeded. Volcanic ash from the volcano fell as far away as mainland Europe, however no disruptions to air traffic were caused.

Weet iemand trouwens nog meer mooie vulkaanfilms naast Volcano en Dante's Peak?

No signs of a eruption at Grímsfjall volcano, harmonic tremors continue
Posted on November 3, 2010 by Jón Frímann
Since 02:30 UTC on the 3rd of November 2010 there has been constant harmonic tremor in Grímsfjall volcano. It is currently unclear why harmonic tremors are happening at Grímsfjall volcano. But there have been some ideas that this might be because a small eruption has started at Grímsfjall volcano.

According to news from few moments ago (around 14:00 UTC) there are no signs of a eruption at Grímsfjall volcano at present time. But harmonic tremors continue at this moment like they have been doing since 02:30 UTC last night.

The possible reason why the scientists dont see any signs of a eruption is because none are visible on the glacier at the moment. But until something appears on surface what is going on in Grímsfjall it is going to remain unclear what is going on at the volcano.

Plotselinge turbulentie gemeten in Grímsfjall vanavond. Steinunn Jakob, geofysicus aan de IJslandse Meteorological Office, zei het moeilijk te zeggen wat er precies gebeurd, maar op ongeveer de helft drie in Grímsfjall onrust heeft verhoogd op basis van de meter. Wetenschappers nu afvragen of de stroom is er veranderd in het vloedwater. Steinunn zegt onrust geeft niet aan dat een uitbarsting op komst is. Vliegtuigen van de kustwacht is nu op weg naar Grímsvötum. Geologen van de Universiteit van IJsland en diensten zijn opgenomen in de beweging om de situatie te beoordelen.

In april kon ik niet naar New York vanwege de vulkaanuitbarsting in IJsland en nu ga ik volgende week voor 3 weken naar Patagonie en begint het gezeik weer... het is dus weer afwachten wat er gaat gebeuren.

Wilde in Chili eigenlijk nog een actieve vulkaan beklimmen maar dat paste helaas niet in het schema, vooral de manier hoe je dan weer naar beneden gaat is geweldig:

kunnen we al ergens wedden of die dit jaar nog gaat uitbarsten?
zo ja, dan zet ik in op wel

New eruption could be looming in Iceland, experts warn

REYKJAVIK An Icelandic volcano has shown signs it could be about to burst into life, just months after an eruption from another volcano caused Europe's biggest air shutdown since World War II, experts said Monday.
"The water levels have tripled in (the river) Gigja since last night," water measurement specialist Gunnar Sigurdsson of the Icelandic Meteorological Institute told AFP.
The water flooding into the Gigja, on the Vatnajoekull glacier in eastern Iceland, comes from an icy lake in the crater of the Grimsvoetn volcano.
Due to increased thermal temperatures, the lake and surrounding glacier area has melted, filling the crater to a point where it has spilled over and caused a so-called river-run, which in turn could easily set off an eruption.
"When a river-run occurs, the pressure, in this case, in Grimsvotn, decreases, and with less pressure, there is a chance of an eruption from the volcano," Thorunn Skaftadottir, a geophysicist also with the Icelandic Meteorological Institute told AFP.
"This is not guaranteed," she pointed out, since an eruption "can only happen if the volcano has collected enough magma."
In 2004, a similar flood from the Grimsvoetn lake was closely followed by an eruption from what is considered Iceland's most active volcano.
Sigurdsson said an eruption was unlikely to occur "until the water levels in Gigja have reached a maximum.
"I don't know when we can expect the levels to reach their highest point, but I suspect it will be in a few days," he said.
Over the past 48 hours, the Meteorological Institute has also registered strong seismic activity in the area, and three moderate earth quakes ranging from 2.7 to 4.0 on the Richter scale.
Icelandic authorities were however unable Monday to say whether an eruption at Grimsvotn would hit air traffic as hard as in April when the Eyjafjoell volcano erupted, dispersing a massive cloud of ash which affected more than 100,000 flights and eight million passengers.
"It is near impossible to say if Grimsvotn erupts whether it will have an affect on air traffic at all," said Keflavik Airport spokeswoman Hjordis Gudmundsdottir, pointing out it would depend if the volcano spewed lava or ash.
"If it is an ash eruption, then it would affect air traffic, but only if it is a strong eruption with ash clouds reaching significant heights," she said, adding "it will also depend on wind, so at this point it is hard to guess."
Skaftadottir meanwhile said that any eruption from Grimsvotn would be an ash eruption.
"However, the scale of the eruption will be much smaller than the Eyjafjoell eruption and I do not think it would have the same effect on air travel as Eyjafjoell did," she said.

Glacier flood from Grímsvötn has peaked, harmonic tremors continue
Posted on November 3, 2010 by Jón Frímann
According to news the glacier flood from Grímsvötn has peaked and is already dropping down. So far there has not been any volcano eruption. But harmonic tremor is still ongoing in Grímsfjall volcano and does not show any signs of stopping. But this harmonic tremor appears to be a bit fluctuating for some unknown reason
