The Science Behind Lightning: Myth vs. Reality

9/11/2024 (Permalink)

Lightning is one of nature's most fascinating and powerful phenomena, captivating and sometimes frightening those who witness its brilliant display. At SERVPRO®, we often hear various myths and misconceptions about lightning, especially when dealing with storm damage and its effects. In this blog, we'll separate fact from fiction, providing you with a better understanding of the science behind lightning.

Myth 1: Lightning Never Strikes the Same Place Twice

This is perhaps the most common myth about lightning. In reality, lightning can and does strike the same place multiple times. Tall structures, such as skyscrapers, trees, and even the ground, can be hit repeatedly. The Empire State Building, for example, is struck by lightning about 20 times per year. The likelihood of multiple strikes increases in areas with frequent thunderstorms.

Myth 2: You Are Safe from Lightning in Your Car Because of the Rubber Tires

While it's true that sitting in a car can offer protection from lightning, it's not because of the rubber tires. The safety comes from the metal frame of the vehicle, which acts as a Faraday cage. When lightning strikes the car, the electrical current travels through the metal frame and into the ground, keeping the occupants inside safe. Convertibles and cars made mostly of fiberglass or plastic do not offer the same level of protection.

Myth 3: Lightning Always Strikes the Tallest Object

Though taller objects are more likely to be struck by lightning, they are not the only targets. Lightning can strike anywhere within a storm's reach, which can be up to 10 miles from the storm itself. Therefore, even if you're not near the tallest object, you are still at risk during a thunderstorm.

Myth 4: If It’s Not Raining, You’re Safe from Lightning

This myth can be particularly dangerous. Lightning can strike even if there is no rain. “Bolts from the blue” are lightning strikes that can occur up to 10 miles away from the storm, under clear skies. Always take thunder as a warning sign that lightning is near, and seek shelter immediately.

Myth 5: Lightning Victims Are Electrified and Dangerous to Touch

It’s essential to dispel this harmful myth. Lightning victims do not retain an electrical charge and are safe to touch. Immediate medical attention, including CPR, can be life-saving for a lightning strike victim. If you witness someone being struck by lightning, it's critical to act quickly and seek emergency help.

The Reality of Lightning Safety

Understanding the realities of lightning can help you take appropriate precautions during a thunderstorm. Always seek shelter in a substantial building or a hard-topped vehicle when you hear thunder. Avoid open fields, hilltops, and tall, isolated trees. If you are indoors, steer clear of windows, electrical appliances, and plumbing fixtures, as lightning can travel through wiring and pipes.
