Eruptions imminent

Alaskans brace for Redoubt Volcano eruption

By DAN JOLING, Associated Press Writer
Fri Jan 30, 7:32 am ET

ANCHORAGE, Alaska – Hardware stores and auto parts shops scored a post-holiday run of business this week as Anchorage-area residents stocked up on protective eyewear and masks ahead of a possible eruption of Mount Redoubt.

Monitoring earthquakes underneath the 10,200-foot Redoubt Volcano about 100 miles southwest of Anchorage, scientists from the Alaska Volcano Observatory warned that an eruption was imminent, sending experienced Alaskans shopping for protection against a dusty shower of volcanic ash that could descend on south-central Alaska.

"Every time this happens we do get a run on dust masks and goggles," said Phil Robinson, manager of an Alaska Industrial Hardware store in Anchorage. "That's the two main things for eye and respiratory protection."
Customer Ron Cowan picked up gear at the store Thursday before heading off to an auto parts store for a spare air filter.

"I'm older now and I'm being a little more proactive than I was the last time," Cowan said.

When another Alaska volcano, Mount Spurr, blew in 1992, he waited too long.

"The shelves were cleared, so I thought I wouldn't wait until the last minute," Cowan said.

Unlike earthquakes, volcanoes often give off warning signs that usually give people time to prepare.

The observatory, a joint program between the U.S. Geological Survey, the University of Alaska Geophysical Institute and the state Division of Geological and Geophysical Surveys, was formed in response to the 1986 eruption of Mount Augustine.

It has a variety of tools to predict eruptions. As magma moves beneath a volcano before an eruption, it often generates earthquakes, swells the surface of a mountain and increases the gases emitted. The observatory samples gases, measures earthquake activity with seismometers and watches for deformities in the landscape.

On Nov. 5, geologists noted changed emissions and minor melting near the Redoubt summit and raised the threat level from green to yellow. It jumped to orange — the stage just before eruption — on Sunday in response to a sharp increase in earthquake activity below the volcano.

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

The observatory's first call after an eruption is now to the Federal Aviation Administration. The observatory's data collection has become far more advanced in 19 years, as has the alert system.

"Pilots are routinely trained to avoid ash and in what to do if they encounter an ash cloud," Power said. "That kind of thing was not routinely done in the 1980s."

The jet stream can carry ash for hundreds of miles. Ash from Kasatochi Volcano in the Aleutians last August blew all the way to Montana and threatened aircraft, Power said.

Particulate is mildly corrosive but can be blocked with masks and filters.
Power advises Alaskans to prepare as they would for a bad snowstorm: Keep flashlights, batteries and several days' worth of food in the house, limit driving and prepare to hunker down if the worst of an ash cloud hits.

Merely going indoors is a defense against ash. The American Red Cross recommends wearing long-sleeved shirts and long pants outside, plus goggles and glasses instead of contact lenses. If no dust mask is available, an effective respiratory filter is a damp cloth over nose and mouth.
But potential danger all depends on the wind. Mount Spurr erupted three times in 1992. When it blew that June, only climbers on Mount McKinley — about 150 miles north of Anchorage — were affected, Power said. An August eruption dumped significant ash on Anchorage and a September blow sent ash about 40 miles north of Anchorage to Wasilla.

Dust mask customer Elizabeth Keating said Thursday that if the volcano erupts, she expects to stay inside. She bought masks for her school-age grandchildren to carry in their backpacks.

"I want to make sure they're carrying these in case they're en route," she said.

The AVO's website's already overloaded with hits. It would be neat if we could get to see it live on TV if it does blow.

High-speed cameras and HDs...pre-recording for the event...that's the way to do it...

Why do I get the tingling sensation that this is the precursor to that porno she was offered to do? Her husband IS involved, potentially.

How many polar bears have to die just because of Evil Republican Volcanoes?

If this was in California, would CARB require a trapOx in the crater?

I own land 50-60 miles east of Redoubt (on the other side of the Cook Inlet) in the Nikiski area.

If it does a Mt. St. Helens type eruption the shock wave and resulting tusnami will knock the trees down and I won't have to cut them in order to build. Unlikely though, so will keep the chain saw sharpened.

Is there any websites set up showing real-time imagery of this site?

It might be fun to see if you just happen to be the one on the site when it finally blows...

If anything, let's send (insert obvious poster here) there...it could keep him busy enough to almost consider it a job...

There's most of 7.75 hrs of daylight a day now so you need to time your visit to the webcam accordingly. Lot better than last month was. Come July it will be upwards of 20 hrs of daylight a day.

No kidding. She'd probably talk about nothing and make no sense to the volcano, which would get quite ticked and annoyed, and promptly erupt to get rid of her.
