Alert level raised on Alaska’s Cleveland volcano

July 21, 2011ANCHORAGE, Alaska — The alert level for an Alaska volcano is being raised after officials say persistent thermal anomalies have been spotted in satellite data. The Alaska Volcano Observatory on Wednesday raised the level Cleveland Volcano to advisory from unassigned. There is no real-time seismic network at the volcano, located 939 miles southwest of Anchorage on an uninhabited island. Officials are not able to track local earthquake activity related to volcanic unrest. Short-lived explosions with ash clouds or plumes exceeding 20,000 feet above sea level are frequent on Cleveland. It last showed signs of unrest last summer, with a small ash emission and lava flows on its upper flanks. –Kansas City

    Hey alvin, I been following this site for awhile.keeps me up to date on all the changes going on with our planet. Can you look at this link

    and tell me your take on the talk about planet x,elenin and such. Some out there are nuts. And some seem to be educated and well informed about our solar system. Thanks. In jesus name,mark


    • Mark, a brown drawf is not a comet and a comet is not a brown drawf. Yes, a brown drawf can be in suspension outside a solar system and oscillate in movements but they are not comets. If the comet has a fixed trajectory orbit through our solar system as these people are plotting it…that means it could have been here before. If it didn’t destroy the Earth on the initial pass, why would it do so now? Gravity of the Earth is never determined by a comet- it’s determined by the Sun which contains 99.99 % of the mass of the entire solar system. Yet, I’ve seen videos of people claiming brown drawf stars are sailing over Antarctica in Youtube videos and my question is where is this object now and how do you hide something which is supposed to be 5 times the mass of Jupiter in our solar system from amateur astromers the world over. I’ve stayed out of the Elenin debate because I think most of the information out there on this comet, whether by mistake or design, is utter nonsense.

      God bless,

        ok thank you for your input, much appreciated

        Glad you commented on this Alvin. The few articles / videos I viewed just didn’t seem very credible, but I am no expert.

        I kinda thought it must be a lot of hoopla about nothing since you stay right of top of realistic threats and events, but had not posted a report.

    Recent satellite images of a remote Alaska volcano along a flight route for major airlines show the mountain may be poised for its first big eruption in 10 years, scientists said on Thursday. The Alaska Volcano Observatory has issued an eruption advisory for the 5,676 foot-tall Cleveland Volcano, located on the uninhabited island of Chuginadak in the Aleutian chain about 940 miles southwest of Anchorage. The advisory was based on “thermal anomalies” detected by satellite, the observatory said. Those measurements indicate the volcano could erupt at any moment, spewing ash clouds up to 20,000 feet above sea level with little further warning, the observatory said. A major eruption could disrupt international air travel because Cleveland Volcano, like others in the Aleutians, lies directly below the commercial airline flight path between North America and Asia, said John Power, scientist-in-charge at the Alaska Volcano Observatory. The volcano’s last major eruption came in 2001, when it blasted ash more than 5 miles into the sky and spilled lava from the summit crater. Cleveland has experienced several smaller eruptions or suspected eruptions since then.

    So far, airlines have not changed their flight patterns because of Cleveland’s heat emissions, said Steve McNutt, a University of Alaska Fairbanks scientist who works at the observatory. Scientists are not always certain about what is happening at the remote volcano, observatory officials said. The town of Nikolski, the nearest settlement to Cleveland Volcano, is 45 miles away. Although Cleveland is among the most active of Alaska’s roughly 90 volcanoes, no seismic equipment is set up there because the costs of working in such a remote area are prohibitive, observatory officials said. Still, Cleveland is the only Alaska volcano blamed for an eruption-caused human death in recorded history. A U.S. soldier who was stationed on Chuginadak Island during World War Two disappeared during an eruption and was presumed killed. Without sophisticated monitors like those used to keep tabs on volcanoes closer to Anchorage and other populated areas, scientists must rely on a variety of other observations to track Cleveland’s eruptions, McNutt said. Those include satellite data, eyewitness reports and video from mariners and pilots in the area.”Cleveland is a particular bugaboo for us because it is right on the air route” with no seismic equipment, Power said.
