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.
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.
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 ...
Cromwell Police started getting 911 calls around 4:30 p.m. about a lightning strike. When first responders arrived, they found a tree that had been hit and three people who were near it.
Lighting Strike and Electrical Shock Survivors International (stylized as LS&ESS) is a non-profit advocacy and support group. Headquartered in Jacksonville, North Carolina , it has chapters throughout the United States and in more than 15 countries. [ 1 ]
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]
