FAIRBANKS — After months of rumbling, Alaska’s Mount Redoubt volcano erupted three times late Sunday and early Monday.

FOX was reporting 4 eruptions at 6 am CDT

It’s a pyroclastic volcano. Keep an eye on this one.

[Izzy Dunne]

I tell you, it’s revenge for Jindal’s “volcano-watching” budget comment...

Humph. The Web Bots may have been right about a natural-type disaster in the upper N.W., but their timing, and maybe the impact, were a little off. Amazing.

They were right about ships grounding or colliding in the Atlantic, too. Sheesh. Whoever came up with the Web Bot idea was a quantum genius.

pyroclastic

Why? What's the difference between this and any other volcano? (Dictionary didn't help)

I don’t know if pyroclastic is the most descriptive of Redoubt, it will create a huge lahar or steam hot mud avalanche, it is a strato volcano, over 10,000 feet high, it can erupt cataclysmic like Krakatoa or Mt St Helens.

Why? What's the difference between this and any other volcano?

This volcano's eruptions are the direct result of 8 years of the Bush administration's failed polices...and global warming!!!

[uglybiker]

Check out the local weather radar.

[Clive]

Pyroclastic flow is more dangerous and affects more territory than the lava flows that you see in night pictures from Hawaii.

Mt Pinatubo was a pyroclastic eruption as was Mt St Helens.

[Smokin' Joe]

Shield volcanoes have a low viscosity magma, (think Hawaii), volcanoes which have composite cones, of layered pyroclastic debris and lava tend to have more viscous lava, and can erupt explosively (Mt. St. Helens).

[Eye of Unk]

The last couple of eruptions I have seen, Mt. Spurr and Mt. Augustine basically melted all the snow and ice and sent ash up in the air, the caldera did not collapse or blow out like Mt St Helens, not to say it can’t happen, but hoping it won’t because any type of massive eruption laterally would destroy most of anything in the Cook Inlet including Anchorage.

it can erupt cataclysmic like Krakatoa or Mt St Helens.

Oh crap. In that case, I hope the Web Bots are WAY off this time. According to them, something real bad is going to happen up there. They thought "maybe a comet?" or something like that would hit. They predicted the "impact", or whatever the disaster was, would happen around December. (After that, the middle to lower East coast would get hit big time by another disaster).

Thank goodness we have strong leaders in Washington, just in case ( NOT!! )

[wolfcreek]

We had a large brush fire here in central Texas that made it's own clouds and showed up on the radar.

[Virginia Ridgerunner]

I thought that it was Sarah Palin’s fault...

[Dustoff45]

Here is an active radar loop that shows us real time.

[Eye of Unk]

Our volcano’s are mostly strato-volcano’s, very tall cone shaped, we are at the northern part of the Ring of Fire, we have a LOT of seismicity, like thousands of little pressure pop-off valves all the time, which is good.

Krakatoa collapsed and sea water rushed in, and it blew up, not so easy to happen here but could happen to St. Augustine, it is its own island.

[Virginia Ridgerunner]

Hey Unk, how far are you from this volcano? Are you seeing any ash?
