Eyes on El Hierro But Cleveland in Aleutian Islands Status at Orange – Alaska Volcano Observatory News

28/09/2011

by BuildFutureEnergy

As El Hierro is on high alert and the earthquake swarms in Spain continue, causing authorities in the Canary Islands to take precautions by evacuating tourists and residents, the Aleutian Islands located in the Alaska area, having been rocking with some significant seismic activity.  The Alaska Volcano Observatory has been monitoring one volcano in particular – Cleveland.

CLEVELAND AVIATION STATUS IS SET TO ORANGE AT THIS TIME.

This past week has also seen the sun shoot off some powerful CME’s, partially directed at Earth, and this geomagnetic phenomena may be to blame.  These two recent articles may be of interest: NOAA Report – Solar Geomagnetic Storm that Partially Hit Earth – Coinciding with Earthquake & Volcano Activity and Could the Sun Set Off the Next Natural Disaster.

The following is today’s report from the observatory:

ALASKA VOLCANO OBSERVATORY CURRENT STATUS REPORTWednesday, September 28, 2011 1:50 PM AKDT (Wednesday, September 28, 2011 21:50 UTC)

CLEVELAND VOLCANO (CAVW #1101-24-)
52°49’20” N 169°56’42” W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Satellite views detected continued elevated summit temperatures at Cleveland Volcano over the past 24 hours. Satellite data also suggest that the lava dome continues to slowly grow as the eruption at Cleveland continues. AVO has received no other reports of activity at Cleveland.

As the lava dome continues to grow in the summit crater, the possibility of an explosive event increases. With continued lava dome growth, lava may eventually overflow the crater rim to produce a lava flow and/or collapse to produce pyroclastic flows. Sudden collapse of the effusing lava could result in the generation of a volcanic ash cloud. However, lava may continue to erupt without an explosive event. It is possible that explosions from the summit crater vent could produce ash clouds that may exceed 20,000 ft above sea level. These events can occur without warning and may go undetected in satellite imagery for hours. However, lightning associated with significant ash-producing events many be detected within minutes using an automated alarm system.

Satellite radar image loop (August 7,18,29, September 9, 20) from the TerraSAR-X sensor of the summit of Cleveland Volcano showing the summit crater and growth of the lava dome. The summit crater is about 200 meters across.

Note that satellite radar images have some inherent topographic distortion due to the manner in which they are collected.

AVO does not have a real-time seismic network on the volcano and thus we are unable to track local earthquake activity related to volcanic unrest, provide forecasts of eruptive activity, or confirmation of explosive, ash-producing events. In the event of a large explosive eruption like that in 2001, it is possible that seismic signals may be recorded on AVO seismic networks at nearby volcanoes. AVO will continue to monitor the volcano using multiple sources of satellite lightning detection, and distant seismic data.

  1. Checking on volcanic activity. Note the increased Geomagnetic storm directed at the Footsool. Technical Galactic Science.
    Volcanoes activated by the Star. Receiving Volcanoes, take in Star Plasma , while venting volcanoes return it to local and System Stars.

    See texts, The Atlantis Hypotheses and The Lord of Atlantis by R S Hislop!!!

    Currently problems with financial services NOT to liking of local star. VERY ANGRY as in 1914 and 1939!!!

    It appears locals are more intersred in so called man made global warming than in real Galactic Science. UPSET local STAR BIG TIME!!! Star make point with Volcanic Activity. Targert date 2012!!!

    Tidy up bankig mess, no problem. Fail to do so, MAYA KATT potentaily make VERY BIG MESS!!!

  2. […] UPDATED SEPT 29TH: NOTE: [Cleveland Volcano Aleutian Islands Status on Orange – Alaska Observatory Reports] […]
