Alaskan Volcano–and its AWAKE!

Alaska volcano has geologists on alert

ANCHORAGE, Alaska – Mount Redoubt, a volcano 100 miles southwest of Anchorage, is rumbling and simmering, prompting geologists to warn that an eruption may be imminent.

Scientists from the Alaska Volcano Observatory have been monitoring activity round-the-clock since the weekend.

On Thursday, the observatory said: “Seismicity remains above background and largely unchanged with several volcanic earthquakes occurring every hour.”

The last time the 10,197-foot peak blew was during a five-month stretch starting in December 1989. It disrupted international air traffic and placed a layer of volcanic dust throughout the Anchorage area.

Volcanoes in Alaska, including Redoubt, typically erupt explosively, shooting ash almost eight miles high. Volcanic ash features small, jagged pieces of rock and glass.

This differs from volcanoes in Hawaii, which usually have slow rolling lava ooze out.

The difference is gas trying to escape gets blocked, possibly by a lava dome or a viscous magma that increases the power from beneath, said observatory geologist Jennifer Adleman.

“Its pressure keeps building and building,” she said.

Depending on wind, the ash plume could be pushed straight at Anchorage, the state’s largest city. This has prompted state and city officials to post bulletins on how to deal with the ash. Tips include staying inside, wearing a mask or wet bandanna if going outside and wearing goggles over contact lenses.


Ok, I knew Alaska had earthquakes, I knew it had pretty BAD earthquakes (one of the largest quakes of the 20th century occurred in Alaska in the early 60’s)

But I never knew it had volcanoes, much less ACTIVE volcanoes….this is slightly alarming to me…..coupled with the rash of quake swarms in Yellowstone….I wonder if we are in for some volcanic activity?

Alaska doesnt concern me as much as Yellowstone, because Yellowstone is a SUPER Volcano, one with the potential to interfere with the climate and potentially wipe out species.  Yes….volcanoes can do that, just research the Siberian Event.  Anyway….this bears watching because I read that the melting of the polar ice would release pressure on earth’s mantle, which would allow volcanic action to heat up (no pun intended).  This bothers me because I can see that it could mean a change (if not elimination) of the growing cycle, a very serious change in the conditions needed for current species to survive.  Ive seriously considered building a greenhouse, and am looking into alternative energy sources..

    Or something like that.
    Volcanoes scare me. As do hurricanes, tornadoes, tsunamis, earthquakes, lightning, thunder,and many other naturally occurring phenomena.
    Simply because they are DEADLY.
    And I prefer to not die until I’m at least 45, thanks. 😛 Err, somewhere around there anyway 😛

  2. well maybe not immediately LOL, but SOON 😛

  3. …see?!??!?!? SOON is SOON-like!!!! 😛
