#1 Volcano ash: Threat of second volcano Katla '10 times the strength'04-21-2010, 12:15 PMVolcano ash: Threat of second volcano Katla '10 times the strength'
A second volcano in Iceland could erupt with 10 times the force of Eyjafyoll if history repeats itself, scientists have warned.

Katla lies next to the volcano currently causing worldwide travel chaos with molten lava and ash shooting into the sky. The last time Eyjafyoll erupted in 1821-23, Katla followed shortly afterwards. The same pattern occurred in 1612.
Katla erupts approximately every 60 years but has not done so since 1918, when it was 10 times as powerful greater than the ongoing activity in Eyjafyoll.
Assistant professors Andy Hooper and Joris Melkert, from the University of Delft in the Netherlands, said the ongoing activity could cause trouble for months.
“If Katla were to erupt, the potential for travel chaos and economic damage would be much greater than has occurred in the last few days,” they said. “A new volcanic dust cloud potentially heading towards the United Kingdom underlines the very real danger that Eyjafyoll could potentially sputter on for months or even more than a year.
“Even in the scenario that Katla doesn’t erupt, disruption could be continuous for many months to come from Eyjafyoll.”
Profs Hooper and Melkert said in 1783-4, the eruption of the Laki volcano in Iceland caused temperatures to fall by three degrees Celsius, killed a quarter of the population and led to thousands of deaths in the Britain due to poisoning and cold temperatures. The last time Katla erupted on such a scale was in 934 AD.
The scientists said all the signs suggested that new magma was still being produced deep within the earth’s crust which meant the volcano would continue to erupt for some time to come.
They added that global warming only increased the level of volcanic activity.

Wonderful news. Thanks for cheering me up this evening.
I'm supposed to be in Belgium for work next week. Even though the airspace has re-opened, there is a severe backlog in passenger traffic, so it looks like I will have to find alternative means of transport.
The whole thing has also made me aware of how much supermarket produce is freighted in, and I've been paying more attention to labels lately. Here's a sample of what's in my fridge at the moment:
Mint (herb): Israel
Lemon Grass: Thailand
Jumbo salad onions: Mexico
Shiitake mushrooms: OMG, they come from Lancashire, UK.
This is bloody ridiculous. I hate conceding to them, but the Greens have a totally valid point about food mile wastage. Almost every item on that list could have been grown in the UK. Mint (herb) is almost a weed, it grows so well. Rhubarb is in season in the UK until the end of May.
I'm going to start going to farmer's markets from now on.20010911

In hockey, it means you have to sit in the penalty box for five minutes.

This is all because pf global warming, you see the CO2 goes into the air and it heats the center of the earth, this causes the moon to tilt which adds pressure to the volcano and then viola, all planes are grounded. Isn't that right Wilbur? :DI predict future happiness for Americans if they can prevent the government from wasting the labors of the people under the pretense of taking care of them.

The last time Katla erupted the mouth of the Mississippi River froze over. The eruption of this volcano would be catastrophic with temperatures plummenting.
