Volcanic eruption - Alaska

This article has great photos.

Flight traffic has been affected by the ash cloud, which prevents airline pilots from flying through the cloud. Photo courtesy the Alaska Volcano Observatory.

Ash continues to spew from the Umnak Island in the Aleutians. On Saturday a volcano erupted, which filled the Aleutian skyline with a thick cloud of smoke and ash.


John Power, an observatory physicist, said the volcano is in an almost continuous state of eruption. Power said that there was a possibility that the volcano could be producing lava, however the ash cloud is too thick to make such a determination.

According to a satellite imagery analysis, one side of the volcano is displaying a thermal anomaly.

The ash plume stretches more than 6 1/2 miles high, some of which was reported in Dutch Harbor on Saturday.

No accumulation has been reported since.

The volcano has not erupted since 1997.

Re: Volcanic eruption - Alaska

Interesting fact - eruption was saturday 11:43 local time.

There was a 5.9 earthquake in NZ saturday morning at 12:08 local time.

But then, when I talk to Sally, it seem's like our close longitude should make us close in time. But someone had to mess around with the dates.

However.............there just MUST be a connection.

Re: Volcanic eruption - Alaska

Earthquake and volcanic activity catalyzing distant geologic events have been correlated over long distances; it's been explained as reflection (p-wave) action on primed faults and surficial magma vaults (the mechanics are quite different for fault earthquakes and volcanic-associated earthquakes).

Note the pattern across the South Pacific. These might be distance correlated events, as many regional events are similar in magnitude. Same type pattern noted during Sichuan earthquake.

(We now have 2 volcanoes erupting, one of which is going code red.
A good status site is at http://www.avo.alaska.edu/activity/avoreport.php?view=update )


Volcano alert up to code red

ANCHORAGE, Alaska -- Okmok volcano's alert level went up to code red-warning status early Friday afternoon.

The volcano blew more ash into the air at midday.

Pilots reported ash to 40,000 feet, with satellite data confirming the cloud.

Winds are carrying the ash southeast. Some ash-fall could occur around the immediate area and on the eastern portions of Umnak Island.
The Alaska Volcano Observatory says lava or mud flows could also occur in the caldera.

The Aleutian arc volcano has been restless since it resumed activity earlier this month.
