Alaska Volcano Observatory's Twitter

I am now following the Alaska Volcano Observatory's Twitter with it set to send the message to my Iphone device. That way I hear a "ding" when they make their posts.

To get the most information you need to follow their TinyUrl - the latest one mentions an observation flight (no . . . I would not want to be in THAT plane right now) that reported no ash emission, significant steaming from a new melt depression near the vent from the 1989-1990 eruption.

I googled Volcano Alert Systems and got this info from: Volcano Live John Search.

Alaska Alert System

Green
Volcano is in typical background, noneruptive state or, after a change from a higher level, volcanic activity has ceased and volcano has returned to noneruptive background state.

Yellow
Volcano is exhibiting signs of elevated unrest above known background level or, after a change from a higher level, volcanic activity has decreased significantly but continues to be closely monitored for possible renewed increase.

Orange
Volcano is exhibiting heightened or escalating unrest with increased potential of eruption, timeframe uncertain, OR eruption is underway with no or minor volcanic-ash emissions.

Red
Eruption is imminent with significant emission of volcanic ash into the atmosphere likely OR eruption is underway or suspected with significant emission of volcanic ash into the atmosphere.


The Volcano Live site has lots of interesting information about what is going on with volcanoes around the world.

Nature is indeed fascinating!
