Survival from a lightning strike depends on the strike’s pathway through the body, immediate medical response, and sheer chance.
It’s natural to feel a sense of awe, and perhaps a little apprehension, when thinking about lightning. This powerful natural phenomenon can seem terrifying, yet many individuals do survive its direct impact. Let’s explore the science behind these remarkable survivals.
The Raw Power of Lightning
Lightning is an immense electrical discharge, a sudden release of energy from the atmosphere. It’s a natural wonder, but also a force of incredible power.
When we talk about lightning, we’re discussing millions of volts and tens of thousands of amperes. To put that in perspective, a typical household outlet is just 120 volts and 15-20 amperes. Lightning’s energy is vastly greater.
Lightning forms from charge separation within storm clouds as ice crystals and water droplets collide. This creates areas of positive and negative charge, with the ground often developing a positive charge below.
Eventually, a “stepped leader” of negative charge descends from the cloud, seeking a path to the ground. As it nears the ground, an upward “streamer” of positive charge rises to meet it. When these connect, the main discharge, known as the “return stroke,” occurs, creating the visible flash of lightning.
