Volcano lightning

A new report revealed that volcanic lightning storms can be as powerful as giant Great Plains thunderstorms and that more lightning means a bigger plume of ash. (National Geographic)

  1. There are at least two types of volcanic lightning, a new radio-mapping study found. One occurs at the mouth of the volcano, and the other2014as shown over Chile's Puyehue-Cord00f3n Caulle volcano complex in 20112014electrifies the heights of the plume, possibly as rising water becomes a mix of droplets and ice-coated ash particles.

  3. It wasn't the lightning but rather the widespread ash clouds from the April 2010 eruption of Iceland's Eyjafjallaj00f6kull volcano (pictured) that eventually grounded a hundred thousand flights. Photograph by Lucas Jackson, Reuters Click here to see more National Geographic photos.

  4. 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.

  5. Volcanic lightning is seen over the Puyehue volcano, over 500 miles south of Santiago, Chile, Sunday June 5, 2011. Authorities have evacuated about 600 people in the nearby area. The volcano was calm on Sunday, one day after raining down ash and forcing thousands to flee, although the cloud of soot it had belched out still darkened skies as far away as Argentina.
