Lightning injuries are divided into direct strikes, side splash, contact injury, and ground current. [1] Ground current occurs when the lightning strikes nearby and travels to the person through the ground. [1] Side splash makes up about a third of cases and occurs when lightning strikes nearby and jumps through the air to the person. [1]
A lightning strike or lightning bolt is a lightning event in which an electric discharge takes place between the atmosphere and the ground. Most originate in a cumulonimbus cloud and terminate on the ground, called cloud-to-ground (CG) lightning.
A ground current, the electricity that flows through the ground away from the point where lightning strikes, puts anyone nearby the strike at risk of shock.
Current from arm to arm, or between an arm and a foot, is likely to traverse the heart, therefore it is much more dangerous than current between a leg and the ground. This type of shock by definition must pass into the body through the skin. Microshock: Very small current source with a pathway directly connected to the heart tissue. The shock ...
Lightning-induced magnetic anomalies can be mapped in the ground, [123] [124] and analysis of magnetized materials can confirm lightning was the source of the magnetization [125] and provide an estimate of the peak current of the lightning discharge.
The presence of fulgurites in an area can be used to estimate the frequency of lightning over a period of time, which can help to understand past regional climates. Paleolightning is the study of various indicators of past lightning strikes, primarily in the form of fulgurites and lightning-induced remanent magnetization signatures. [1]
Lightning over Rymań. Northern Poland. Perhaps the best known example of a natural spark is lightning. In this case the electric potential between a cloud and ground, or between two clouds, is typically hundreds of millions of volts. The resulting current that cycles through the stroke channel causes an enormous transfer of energy.
A New Jersey man was warning people on the beach about an incoming storm when he was fatally struck by lightning over the weekend, police said. New Jersey man trying to warn beachgoers about storm ...
