Quando aparece um digno de passar na tv?

Pessoalmente acho que tudo isto é mais digno de passar na TV do que a maior parte do lixo que lá vejo quando a ligo.

Seja como for vulcanologia não é adivinhação. Há probabilidades de as coisas acontecerem, mas nunca se sabe com 100% de certeza antes de acontecerem. Teoricamente, a probabilidade de o Katla entrar em erupção nos próximos meses é a maior de sempre, desde os últimos 90 anos.

A nós, comuns mortais, resta-nos aguardar. Smile

Entretanto, nas últimas 48 horas os sismos sobre o Katla acalmaram...

Iceland’s Eyjafjallajökull Still Rumbles

A farmer living close to the glacier-volcano Eyjafjallajökull in south Iceland told the newspaper DV yesterday that he had heard the glacier rumble and that the noise was similar as to when it last erupted in the spring of 2010, just not as loud.

“It might very well be true. If the wind is blowing in your direction, you hear it once in a while,” policeman at Hvolsvöllur Kristján Gudmundsson told mbl.is.

Gudmundsson said more people living in Rangárthing eystra have reported rumblings in the glacier under such wind conditions.

“I don’t know what it means and it is difficult to predict anything. It started without notice last time and we know that the crater is still open and boiling,” he added.

According to information from the Icelandic Meteorological Office, there is nothing that indicates increased seismic activity in Eyjafjallajökull. Earthquakes are monitored around the clock at the Meteorological Office.

Note-se que ainda estamos dentro da janela de 6 a 18 meses dentro da qual historicamente uma erupção do Katla se tem sucedido às erupções do Eyjafjallajökull. Smile

ICELAND’s second largest volcano looks set to blow, bringing far more chaos than last year’s eruption, geologists warned yesterday.

Professor Pall Einarsson, of the University of Iceland, said unprecedented tremors gave good reason to worry.

He added: “There is no doubt that lava there is slowly growing.”

(...)

In comparison, the volcano which brought air traffic to a standstill last year, is tiny.

Geologists detected the high risk of a new eruption after evaluating an increased swarm of earthquakes around the island's second largest volcano.

Pall Einarsson, a professor of geophysics at the University of Iceland, says the area around Bárdarbunga is showing signs of increased activity, which provides "good reason to worry".

He told the country's national TV station that a low number of seismometer measuring devices in the area is making it more difficult to determine the scale and likely outcome of the current shifts.

But he said there was "every reason to worry" as the sustained earthquake tremors to the north east of the remote volcano range are the strongest recorded in recent times and there was "no doubt" the lava was rising.

The geologist complained that the lack of coverage from measuring devices means he cannot accurately detect the depth and exact location of the increased number of localised earth movements.

(...)
Respected volcano watcher Jón Frímann, said on his volcano watch blog: "After the Eyjafjallajökull volcano eruption in the year 2010 it seems that geologists in Iceland take earthquake swarms more seriously then they did before."

He explained the Icelandic Met Office had on Sunday warned of the increased risk of a eruption in north-west side of Vatnajökull glacier due to the high earthquake activity in the area, and added: "It is clear that only time is going to tell us if there is going to be a eruption in this area soon or not."

Ainda é cedo para tirar conclusões precipitadas. O melhor para já é deixar os media soltar a franga, esperar uns tempos e depois ver se sim ou sopas.

Em qualquer caso... Go Iceland, go Iceland! .w.

EDIT:

Icelandic Met Office escreveu:

Presently, there are no signs of an imminent volcanic eruption in Iceland. The Icelandic Meteorological Office (IMO) did not issue a warning last weekend in connection with increased seismicity beneath the Vatnajökull ice-cap. If signs of an eruption were apparent, IMO would issue a warning immediately.

REYKJAVIK, Iceland — Iceland's most active volcano erupted Saturday, with a white plume shooting 18,000 feet into the air, scientists said.

The eruption was followed by around 50 small earthquakes, the largest of which measured 3.7 on the Richter Scale, according to Iceland's meteorological office.

There was a similar eruption at the same volcano in 2004.

Scientists don't believe this eruption will lead to air travel chaos like that caused by ash from the Eyjafjallajokul volcano in April 2010.

The Grimsvotn volcano is located underneath the Vatnajokull glacier in southeast Iceland.

Sparsely populated Iceland is one of the world's most volcanically active countries and eruptions are frequent.

They often cause local flooding from melting glacier ice, but rarely cause deaths.

Last year's Eyjafjallajokul eruption left millions of air travelers stranded after winds pushed the ash cloud toward some of the world's busiest airspace and led most northern European countries to ground all planes for five days.

In November, melted glacial ice began pouring from Grimsvotn, signaling a possible eruption. That was a false alarm but scientists have been monitoring the volcano closely ever since.
