The 2010 eruptions of Eyjafjallajökull were volcanic events at Eyjafjallajökull in Iceland which, although relatively small for volcanic eruptions, caused enormous disruption to air travel across western and northern Europe over an initial period of six days in April 2010. Additional localised disruption continued into May 2010. Volcanic lightning is an electrical discharge caused by a volcanic eruption, rather than from an ordinary thunderstorm. Volcanic lightning arises from colliding, fragmenting particles of volcanic ash and sometimes ice, which generate static electricity within the volcanic plume. Volcanic eruptions have been referred to as dirty thunderstorms due to moist convection and ice formation that drive the eruption plume dynamics and can trigger volcanic lightning. But unlike ordinary thunderstorms, volcanic lightning can also occur before any ice crystals have formed in the ash cloud. The earliest recorded observations of volcanic lightning are from Pliny the Younger, describing the eruption of Mount Vesuvius in 79 AD, `There was a most intense darkness rendered more appalling by the fitful gleam of torches at intervals obscured by the transient blaze of lightning.
