8. The Blue Lightning of Volcanic Eruptions
Advertisement
One of the most amazing shows nature offers when a volcano erupts is volcanic lightning. Although most volcano lightning is white or orange, under some circumstances observers have seen flashes of beautiful blue lightning amid the ash and smoke. Sometimes known as "blue volcanic lightning," this unusual occurrence arises from the interaction of sulphur compounds expelled during an eruption with electrical discharges. Sulphur in the volcanic plume can cause the lightning's colour to veers towards the blue end of the spectrum, producing an amazing show of azure bolts against the black background of ash and clouds. Researchers of blue volcanic lightning aim to provide understanding of the chemical makeup of volcanic emissions and the electrical mechanisms running inside eruption columns. This study might result in better techniques for tracking and forecasting volcanic activity, hence possibly saving lives in places likely to be erupting. Blue lightning during volcanic eruptions reminds us sharply of the strong forces operating beneath the surface of Earth and the intricate interplay among geological and atmospheric phenomena.
