Alaska's Mount Redoubt Volcano to Erupt Again in Days »
Posted By y_soitenly 9 months, 3 weeks ago in NewsThe Alaska Volcano Observatory (AVO) said that experts who were monitoring the situation around-the-clock believed that the volcano could erupt anytime soon, in a time frame between a couple of days and a couple of weeks. There's no way to tell for sure when the catastrophe will happen, as scientists have no direct way of measuring the pressure build-up in the inner chambers of the mountain. When that pressure will peak and reach the maximum amount the rock above can withstand, it will erupt with incredible force and will throw ash, rock fragments and molten lava high into the atmosphere.

In the city of Anchorage, authorities already advised citizens to make ready for a potential disaster, and urged them to start stockpiling supplies and food, such as canned meat, non-perishable goods, plastic bags, respiratory aids and wind-washer fluid for their vehicles, in the event of an ash cloud affecting the city.

I recently saw this mentioned on The Weather Channel and they say that when this volcano erupts, it could send clouds of ash, with a tail-wind, more than 800 miles away. It could also affect citizens of Canada and the western coast of the US.

Alaska's volcanoes are not like Hawaii's. "Most of them don't put out the red river of lava," said the volcano observatory's John Power.

Instead, they typically explode and shoot ash 30,000 to 50,000 feet high — more than nine miles — into the jet stream.
"It's a very abrasive kind of rock fragment," Power said. "It's not the kind of ash that you find at the base of your wood stove."
The particulate has jagged edges and has been used as an industrial abrasive. "They use this to polish all kinds of metals," he said.
Particulate can injure skin, eyes and breathing passages. The young, the elderly and people with respiratory problems are especially susceptible. Put enough ash under a windshield wiper and it will scratch glass.
It's also potentially deadly for anyone flying in a jet. "Think of flying an airliner into a sandblaster," Power said.
Redoubt blew on Dec. 15, 1989, and sent ash 150 miles away into the path of a KLM jet carrying 231 passengers. Its four engines flamed out.
As the crew tried to restart the engines, "smoke" and a strong odor of sulfur filled the cockpit and cabin, according to a USGS account. The jet dropped more than 2 miles, from 27,900 feet to 13,300 feet, before the crew was able to restart all engines and land the plane safely at Anchorage. The plane required $80 million in repairs. -
