## How Far Underwater Does Lightning Travel Scuba Diving?
Lightning is a powerful natural phenomenon that can occur anywhere in the world, including underwater. While it is relatively rare, lightning strikes underwater can be extremely dangerous for scuba divers.
### How Does Lightning Travel Underwater?
Lightning is a discharge of electricity that occurs between two objects with different electrical charges. The most common type of lightning is cloud-to-ground lightning, which occurs when a negatively charged cloud discharges electricity to positively charged ground.
Underwater lightning can occur when there is a difference in electrical charge between the water and the air. This can happen when there is a storm overhead, or when there is a large amount of metal in the water.
When lightning strikes underwater, it travels through the water in the form of a plasma channel. A plasma channel is a hot, ionized column of gas that can conduct electricity. The plasma channel can travel for long distances through the water, and can even reach the surface.
### How Far Underwater Can Lightning Travel?
The distance that lightning can travel underwater depends on a number of factors, including the strength of the lightning bolt, the conductivity of the water, and the depth of the water.
In general, lightning can travel for hundreds of feet underwater. However, the distance decreases as the depth of the water increases. This is because the water becomes less conductive as it gets deeper.
### Dangers of Lightning Underwater
Lightning strikes underwater can be extremely dangerous for scuba divers. The plasma channel can cause burns, electrical shock, and even death.
In addition, lightning can also cause a number of other hazards for scuba divers, including:
Electromagnetic pulse: The electromagnetic pulse created by a lightning strike can damage electronic equipment, such as dive computers and cameras.
Shock waves: The shock waves created by a lightning strike can cause damage to the inner ear, leading to hearing loss or vertigo.
Debris: A lightning strike can dislodge debris, such as rocks and coral, which can fall on scuba divers.
### How to Stay Safe from Lightning Underwater
There are a number of things that scuba divers can do to stay safe from lightning:
Check the weather forecast before diving. If there is a storm overhead, it is best to postpone your dive.
Be aware of your surroundings. If you see any signs of lightning, such as flashes of light or thunder, get out of the water immediately.
Stay away from metal objects. Metal objects can conduct electricity, which can increase your risk of being struck by lightning.
Carry a lightning detector. A lightning detector can help you to predict when lightning is likely to strike.
Follow the advice of your divemaster or instructor. Your divemaster or instructor will be able to provide you with specific advice on how to stay safe from lightning underwater.
### Conclusion
Lightning strikes underwater can be extremely dangerous for scuba divers. However, by following the safety guidelines above, you can help to reduce your risk of being struck by lightning.
