Can crouching behind a rock help during a lightning event?

Understanding the Risks of Lightning Strikes

When a lightning strike occurs, it can heat the air around it to temperatures of up to 50,000°C, creating a massive electrical discharge that can travel through the ground and conduct through objects in contact with the earth. Crouching behind a rock may provide some protection from the initial blast and heat, but it will not shield you from the electrical discharge that can travel through the ground and through objects.

Choosing a Safe Location

If you’re caught outdoors during a lightning storm, look for a safe location that is at least 15 feet away from any objects that can conduct electricity, such as trees, power lines, or metal fences. Avoid areas with standing water, as this can increase your risk of being struck. If no such location is available, a small group of people can huddle together in a low-lying area, such as a depression in the ground or a ditch. Crouching behind a rock is not a recommended option, as the electrical discharge can travel through the ground and potentially strike you.

Staying Safe During a Lightning Storm

When taking shelter from a lightning storm, stay away from metal objects, such as golf clubs, bicycles, or fences, as these can conduct electricity. Avoid being in contact with electrical appliances, such as phones, radios, or computers. If you’re in a vehicle, do not get out until the storm has passed and the danger has subsided. If you’re in a building, avoid using electrical appliances and stay away from windows and doors.
