Lightning strike

Lightning is a bright flash of power.

Most flashes start in clouds. Some travel from clouds to the ground.

Others go from the ground up to the clouds.

Lightning can be very dangerous. It can cause fires in forests. It can even make rocks shatter.

Lightning can hurt people and animals. It can travel through the ground. This can shock a person's legs.

Animals like cows are at risk. Electricity can flow through their bodies. This can happen if they stand far apart.

There are many strikes every day. Stay safe by staying inside during a storm.

Most strikes start in clouds. Some travel from clouds to the ground. Others go from the ground up to the clouds.

There are about 6,000 strikes every minute. That is over 8 million strikes every day!

Lightning can be very dangerous to people and animals. A direct strike can cause serious harm. It can also cause fires in forests. It can even make rocks shatter. This happens when water inside a rock turns to steam very fast.

Electricity can also travel through the ground. This is called ground current. It can flow through a person's legs. This happens more often than direct strikes. Animals like cows are at risk too. Because their legs are far apart, electricity flows through their bodies easily.

If you are caught in a storm, stay safe. Do not hide under trees. One in four people struck by lightning were under trees. Find a safe, enclosed space instead.

A lightning strike is a sudden flash of electricity. This happens when an electric discharge moves between the atmosphere and the ground.

Most of these strikes begin in a cumulonimbus cloud. They travel down to the earth, which is called cloud-to-ground lightning. Sometimes, lightning moves from the ground up into the clouds. This is called ground-to-cloud lightning and happens from tall objects. Most lightning actually stays high in the sky. These are called intracloud or cloud-to-cloud strikes.

Lightning can hurt people in several different ways. A direct strike happens when a person is part of the electric path. This can cause internal burns or damage to the nervous system. A contact injury happens if a person touches an object that is electrified. Sometimes, electricity can even jump from the main path to a person. This is called a side splash. There are also blast injuries from the loud shock wave.

Electricity can also travel through the surface of the earth. This is called ground current or step potential. When lightning hits, the ground becomes highly electrified. The electricity looks for a good path to move. It often chooses a person's legs to flow through. This ground current causes more injuries and deaths than direct strikes. In Norway, one storm even killed 323 wild reindeer this way.

Lightning is very common all over our world. There are about 6,000 strikes every single minute. This means there are over 8 million strikes every day. In the United States, lightning causes about 51 deaths every year on average. In Kisii, Kenya, about 30 people die from lightning each year. This happens because of many storms and metal roofs. In Australia, about 100 people are injured by lightning every year.

Nature also feels the power of these huge flashes. Lightning can start massive forest fires in places like Siberia. It can even shatter rocks. This happens when water inside a rock turns to steam very fast. The steam makes a small explosion that breaks the rock apart.

If you see a blue haze or smell ozone, a strike might be near. It is best to find a safe, enclosed space right away.

A lightning strike is a powerful event involving an electric discharge. This discharge moves between the atmosphere and the ground.

Lightning is a major part of Earth's weather systems. It carries immense energy through the air in a sudden flash. Scientists study these events to understand electrical patterns in our atmosphere. Understanding lightning helps us protect people, animals, and infrastructure from its power.

Most lightning strikes begin in a cumulonimbus cloud. These are large, towering clouds that form during storms. When the discharge travels from the cloud to the ground, it is called cloud-to-ground (CG) lightning. A different type is ground-to-cloud (GC) lightning. This occurs when lightning starts from a tall, grounded object and moves upward into the clouds.

Most lightning actually happens high in the atmosphere. These are called intracloud (IC) or cloud-to-cloud (CC) lightning events. About 25% of all lightning events involve a strike between the atmosphere and earth-bound objects.

Lightning can injure humans through several specific mechanisms. A direct strike occurs when a person becomes part of the main flash channel. This can cause internal burns and damage to the nervous system. A contact injury happens when a person touches an object that has been electrified. Sometimes, electricity can jump from the main channel to a person in a side splash. A person might also suffer blast injuries from the shock wave or loud thunder.

Even without a direct hit, an electromagnetic pulse (EMP) can affect the body. This pulse can disrupt an artificial pacemaker or cause seizures and cardiac arrest.

One of the most dangerous effects is called ground current, or step potential. When lightning hits the earth, the surface becomes highly electrified. Because the ground has high impedance, the current seeks a better conductor. It often travels through a person's legs to find a path. This can create a voltage difference of several thousand volts per linear foot. This phenomenon causes more injuries and deaths than all direct strikes combined.

In Australia, ground currents account for up to 50 percent of all lightning injuries.

Lightning also poses a major threat to animals, especially large quadrupeds. Animals like cattle, sheep, and horses are at high risk from step potential. Because their legs are spread far apart, the voltage difference between them is large. The electricity travels through their legs and into critical organs like the heart. This can lead to mass deaths of livestock near trees or fences.

In Norway, a single incident killed 323 wild reindeer. Farmers use methods like ground rods or gravel to help protect their herds.

Lightning strikes are incredibly frequent around the world. There are approximately 6,000 strikes every minute. This adds up to more than 8 million strikes every single day. In the United States, lightning causes an average of about 51 fatalities per year. In Kisii, Kenya, about 30 people die annually due to frequent storms and metal roofs. In Britain, between 30 and 60 people are struck each year.

These numbers show how common and widespread lightning activity truly is.

Nature is also physically changed by these electrical discharges. Lightning can start massive forest fires in places like Siberia and the Russian Far East. The smoke from these fires can even cause secondary lightning strikes. Lightning can also shatter rocks through a process involving water. When lightning hits a rock, it rapidly heats the water inside. This water turns into steam so quickly that it causes a steam explosion.

This process can break the rock apart with great force.
