The Icelandic volcano that has kept much of Europe land-bound is far from finished spitting out its grit, and offered up new mini-eruptions Saturday that raise concerns about longer-term damage to world air travel and trade. Facing days to come under the volcano's unpredictable, ashy plume, Europeans are looking at temporary airport layoffs and getting creative with flight patterns to try to weather this extraordinary event. Modern Europe has never seen such a travel disruption. Air space across a swath from Britain to Ukraine was closed and set to stay that way until Sunday or Monday in some countries, affecting airports from New Zealand to San Francisco. Millions of passengers have had plans foiled or delayed. Activity in the volcano at the heart of this increased early Saturday, and showed no sign of abating.Scientists say that because the volcano is situated below a glacial ice cap, the magma is being cooled quickly, causing explosions and plumes of grit that can be catastrophic to plane engines, depending on prevailing winds. In Iceland, winds dragged the ashes over new farmland, to the southwest of the glacier, causing farmers to scramble to secure their cattle and board up windows.In Iceland, torrents of water have carried away chunks of ice the size of small houses. More floods from melting waters are expected as long as the volcano keeps erupting — and in 1821, the same volcano managed to erupt for more than a year.
