Waiting For The Eruption

We are still waiting for, the inevitable it seems, the eruption of Mt. Redoubt.

An article from Alaska Daily News (ADN)

Following is part of a statement, and link, from the Alaska Volcano Observatory (AVO)

“The current activity at Redoubt could be precursory to an eruption, perhaps within days. A further increase in seismicity is expected to accompany an eruption. Staff are currently monitoring the volcano 24 hours a day.”

Couple photos I took today of Lazy Mountain from Wasilla Lake. Some brief holes in the cloud cover.

More on Mt. Redoubt Volcano

Here is an image of Mt, Redoubt Volcano taken during the 1990 eruption.

The mushroom-shaped plume rose from avalanches of hot debris (pyroclastic flows) that cascaded down the north flank of the volcano. A smaller, white steam plume rises from the summit crater.

‘DAYS’: Advisories issued for people to prepare for eruption.

The ground at Mount Redoubt rumbled intermittently Tuesday, and the Alaska Volcano Observatory continued to forecast a potential eruption there “within days.”

The 10,197-foot peak 100 miles southwest of Anchorage now appears ready to explode for the second time in 20 years, the observatory noted in a mid-day status report.

“A further increase in seismicity is expected to accompany an eruption,” the agency said. Observatory staff continue to monitor the volcano 24 hours a day.

If history is a guide, Redoubt should erupt in style, geologists say. Unlike volcanoes in Hawaii, which tend to ooze out slow-rolling lava, volcanoes in Alaska — Redoubt included — usually erupt explosively, shooting ash nearly eight miles high.

That’s because the gas that’s trying to escape the volcano gets blocked, either by a lava dome or thick, syrupy magma — characteristic of the highly viscous material in Alaska volcanoes — which increases the power below, AVO geologist Jennifer Adleman said.

“Its pressure keeps building and building. …”

Then it blows.

Were that to happen around 9 a.m. this morning, the forecast winds would carry the ash plume directly toward Anchorage, according to a chart posted on the Alaska Volcano Observatory Web site Tuesday. The warning prompted both state and city emergency agencies to issue bulletins to residents with advice on how to cope with an ash storm.

Stay inside as much as possible, the Anchorage Office of Emergency Management said. Wear a dust mask or a wet bandana if you venture outdoors. People who wear contact lenses should consider wearing goggles.

Volcanic ash consists of tiny jagged pieces of rock and glass, an advisory posted by the U.S. Geological Survey noted.

“Falling ash can turn daylight into complete darkness. Accompanied by rain and lightning, the gritty ash can lead to power outages (and) prevent communications….”

The last time Redoubt erupted — over a five-month period that lasted from December 1989 through April 1990 — the ash plume disrupted international air traffic and coated Anchorage in a thin layer of volcanic dust.

It also sent “pyroclastic flows” of hot gas and rock rushing down the Drift River drainage, turning ice and snow into a fast moving river of mud, which partially flooded the Drift River Oil Terminal on the western shore of Cook Inlet. The state said Tuesday afternoon that the terminal’s volcano readiness plan is now in effect.

Guess we might want to get ready for this one. It may be a hazard and all that, but I still think it’s really cool.

Down To The Hay Flats

Needed to run an errand in town late this afternoon. After I was done, noticed that the sun was close to setting, so I drove on down to the Palmer Hay Flats to get some photos.

Redoubt volcano has subsided for the time being. They still feel that she may blow any day now though. I’ll be watching 🙂

Redoubt Volcano Update

Inlet volcano quieter but still simmering

Redoubt volcano seems to have simmered down over recent hours, but this morning scientists were still watching for signs of an eruption, according to the Alaska Volcano Observatory.

Scientists upgraded the aviation color code for Redoubt from yellow to orange over the weekend, indicating that an eruption may be imminent. The code remains the same but activity has settled down, without any major shaking since midnight.

“Things have dropped down quite a bit,” said Kristi Wallace, an AVO research geologist.

Geologists may make a flight above the volcano to gather samples of gases later today, she said.

I’m keeping my fingers crossed that we’ll have an eruption.

Redoubt Rumbling Prompts Volcano Alert

So, I guess we are getting a bit of earth activity. An earthquake yesterday, and now Mount Redoubt looks like it might be erupting. Cool stuff!

From ADN:
New seismic activity at Mount Redoubt increased significantly early Sunday and may be the prelude to an eruption, “perhaps within hours to days,” the Alaska Volcano Observatory is reporting.

Geologists upgraded the aviation color code for Redoubt from yellow to orange at 2:09 a.m. Sunday, indicating that an eruption may be imminent.

The volcano, which lies about 50 miles west of Kenai and 100 miles southwest of Anchorage, last erupted over a four-month period, from 1989 to 1990.

Here are some of the birds we get at the feeder.
Sparrows…not sure what kind yet. Playing with some new software, so if the images look a little funky, that’s why. Let me know eh.

5.7 Earthquake

5.7 quake rattles Southcentral

Anchorage Daily News

(01/24/09 09:48:19)

An earthquake with a preliminary magnitude of 5.7 rattled Southcentral Alaska this morning.

The quake, at 9:09 a.m., was centered below Cook Inlet 50 miles west of Homer and 158 miles southeast of Anchorage, according to the Alaska Earthquake Information Center. The shake could be felt in Anchorage.

The West Coast and Alaska Tsunami Warning Center reported the quake to have a preliminary magnitude of 5.7. No tsunami was expected, the center said on its Web site.
