"Experts say one of Iceland's most feared volcanoes looks ready to erupt, with measurements indicating magma movement, raising fears of a new ash cloud halting flights over Europe. The Iceland Civil Protection Authority says it is closely monitoring the situation. "The movements around Hekla have been unusual in the last two to three days," University of Iceland geophysicist Pall Einarsson said." Hekla's eruption would certainly have far more dire consequences on European airspace than Grimsvotn, which merely succeeded in getting Obama to vacate Ireland sooner than expected: "The volcano, dubbed by Icelanders in the Middle Ages as the "Gateway to Hell," is one of Iceland's most active, having erupted some 20 times over the past millennium, most recently on February 26, 2000. Over the past 50 years, Hekla has gone off about once a decade." And so Europe, once again caught in the maelstrom of a sovereign debt crunch, will be sensitive to headline risk, as the last thing the continent which is now doing all it can to ostracize rating agencies, as if its insolvency is their fault, is a continent-wide grounding of all flights.
