Lighting seen amid the lava and ash erupting from the vent of the Eyjafjallajokull volcano in central Iceland early morning Sunday April 18 2010 as it continues to vent into the skies over Europe. Low-energy lightning is sometimes active during eruptions, arcing between particles as they exit the volcanic vent at around 100 metres per second. The dramatic volcanic eruption which has closed Europe's airspace for days has entered a new phase - producing less smoke but bubbling with lava and throwing up chunks of molten rock.
