Redoubt May Erupt Again- AVO Raises Alert after Many Quakes!

REDOUBT VOLCANO (CAVW #1103-03-)
60°29'7" N 152°44'38" W, Summit Elevation 10197 ft (3108 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

AVO raised the Aviation Color Code to YELLOW and the Volcano Alert Level to ADVISORY at Redoubt volcano this morning. A series of small repetitive earthquakes began at 01:44 AKDT (0944 UTC) this today in the vicinity of the volcano's summit. Activity is continuing this afternoon. See www.avo.alaska.edu...

These earthquakes may be precursory to renewed eruptive activity at the volcano and increased instability of the lava dome. Whether this will result in explosive activity or failure of the lava dome is unknown at this time. However, there is a heightened possibility of volcanic activity that would produce a volcanic ash cloud, pyroclastic avalanches, and lahars and flooding down the Drift River.

Yep, that don't look good.

again??????????? busy busy

Yeah, pretty bizarre. I have station RSO up in GEE, along with several others around Redoubt, and only RSO seems to be showing anything. They are real small quakes, but they are consistent, and incessant- one right after the other.

I suppose they will wait until these start increasing in magnitude before any further alert is sounded.

hey thats the volcano i look at from my porch

it went of continually last spring for about 6months.

I can't locate RSO on my GEE - can you tell me what it's near or any other station worth watching nearby? The nearest I have with data available is Kodiak Island

Sure. RSO is part of the Alaska Volcano Observatory. The network is AV.

First, in your station chooser, select "Extremely Short Period"

Next, hit "Add Network"

Add the network AV, with your map zoomed in on Alaska.

You will see a bunch of new stations come up, all over Alaska.

Now in your station chooser, scroll down under AV until you see station AV.RSO, and click it once to see it highlight on the map.

Click Load Realtime Data, and you're in business.

Also note other stations immediately around RSO, and those are the ones monitoring Redoubt. You can open any of those too, but easier. Just click on them in the map, and Load Realtime Data again.

ETA: Actually RSO appears to have stopped transmitting at the moment, but try some of the other ones.

You're a star - much appreciated.

Wow you can see a Volcano from your porch?

I am so jealous of you right now.

actually i can see 3 volcanoes from my porch and windows, Spur, Redoubt, and illamna (i think i spelled illamna wrong haha)

4.7 Alaska, somewhat close to redoubt?

No it was 27 miles away from Anchorage and I think where the volcano is at it's about 300 miles (not 100% sure on the distance) not nowhere near the volcano

Yeah, I see that now after tracking it down. Man, that sukka hit over 5 mm/sec at station SKN. No wonder they upgraded it from 4.2 to 4.7- and it is still pending review by a seismologist.

reply to post by sandman441


its actually less then a 100miles from anchorage, and its less then 20miles from me

thank god for the cook inlet, i would hate to be right next to that bad boy, least this way i can still clearly see it without having to live right next to it haha.

I've actually worked at the drift river facility a few times, its pretty neat being right at its base, it looks surprisingly different from that close, you just see more details and contours.

aw man I thought it was near kenai. I just couldn't remember how close it was. Been way too long since my last Alaska geography class.

Hmmm, definite increase in activity !!

Yes, good catch. I kind of got tired of watching it there a week ago or so, so I quit monitoring it. But yeah, those are the very quick, successive quakes that caused them to raise the alert level, and now they're back. Another one to watch. Star for you, for paying attention! Thanks.
