Is nature trying to wipe out Adelaide? This city was one of many places illuminated as 80,000 lightning strikes lit up the skies of southern Australia last night. A huge storm swept across the region, and lightning bolts triggered fires and power outages in the states of South Australia and Victoria, grounding flights out of Melbourne and destroying a house in its suburb of Prahran.
During an electrical storm, charge builds up inside storm clouds as tiny ice crystals collide, eventually releasing a bolt as electricity leaps from the sky to the ground. It is estimated that lightning strikes a location on Earth about 40 to 50 times every second.
