In April 2010, it was Iceland's unpronouncable Eyjafjallajokull volcano which erupted and forced more than 100,000 flights to be canceled on concern glass-like particles formed from lava could melt in aircraft engines and clog turbines. A year later, in May 2011, ash from Iceland’s Grimsvotn volcano forced flight cancellations in Scotland, northern England and Germany leading to further lower "GDP adjustments" across Europe which back then was in desperate need of a scapegoat for its then double-dip recession.
The eruption of an active volcano in Alaska is causing local carriers to cancel some flights, and could impact commercial airline traffic if it the situation becomes more severe. The plume of ash spewing from Pavlof Volcano, on the Alaskan Peninsula, is currently reaching about 20,000 feet into the air, the altitude at which some small aircraft fly.
Local airlines have been advised to avoid an erupting volcano in Indonesia, the AP reports. Mt. Sinabung, an 8,350-foot active volcano, last erupted in August 2010. This eruption began Sunday. More than 15,000 residents have fled the area, according to the AP.
Mt. Everest might be the tallest mountain on Earth, but it's nothing compared to the tallest volcanic mountain in the solar system, Olympus Mons on our red cousin Mars. John Brady at Astronomy Central shows, in the image below, what this gargantuan feature would look like if it were on the continent of North America — it would completely cover the state of Arizona!
One of Iceland's most feared volcanoes, Hekla, looks ready to erupt, with measurement instruments showing likely magma movement, an Icelandic geophysicist told AFP on Wednesday."The movements around Hekla have been unusual in the last two to three days and have been recorded in five very precise metres placed around Mount Hekla," University of Iceland expert Pall Einarsson said, adding that while this might not necessarily mean an immediate blast, "the volcano is ready to erupt."
