Volcano sparks more flight disruptions

LONDON — A lingering volcanic ash plume forced extended no-fly restrictions over much of Europe Saturday, as Icelandic scientists warned that volcanic activity had increased and showed no sign of abating — a portent of more travel chaos to come. Although the ash plume has grown, a northerly wind was expected to allow enough visibility for scientists to fly over the volcano Saturday. Scientists want to see how much ice has melted to determine how much longer the eruption could spew ash. 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 if prevailing winds are right.
