Lightning arrester, for example, often refers to fused links that explode when a strike occurs to a high voltage overhead power line to protect the more expensive transformers down the line by opening the circuit. https://www.nationalgeographic.com/environment/natural-disasters/lightning Although commonly associated with thunderstorms at close range, lightning strikes can occur on a day that seems devoid of clouds. It may also point to the victim not being directly struck at all, but just being very close to the strike termination.[5].

Then, dividing by three to determine the distance in kilometers, or by five for miles. This phenomenon is responsible for more injuries and deaths than the above three combined, with reports such as "hundreds of reindeer killed by a lightning storm..." being a classic example. The strikes and atmospheric flashes are not predicted, however the level of detail recorded by these technologies has vastly improved in the past 20 years.

NWS
As lower frequencies propagate further along the ground than higher ones, the lower medium wave (MW) band frequencies (in the 500–600 kHz range) can detect lightning strikes at longer distances; if the longwave band (153–279 kHz) is available, using it can increase this range even further.

Lightning strikes can injure humans in several different ways:[4][5], Lightning strikes can produce severe injuries[4], and have a mortality rate of between 10% and 30%, with up to 80% of survivors sustaining long-term injuries. Sound travels at the slower speed of about 340 m/s (depending on the temperature), so the flash of lightning is seen before thunder is heard. However, products and systems have been designed of varying complexities to alert people as the probability of a strike increases above a set level determined by a risk assessment for the location's conditions and circumstances.

The primary conducting channel, the bright coursing light that may be seen and is called a "strike", is only about one inch in diameter, but because of its extreme brilliance, it often looks much larger to the human eye and in photographs. If the damage is severe, the tree may not be able to recover, and decay sets in, eventually killing the tree. Hallucinations may be induced in people located within 200 meters of a severe lightning storm.

And if for some reason you can't make it to a safe location, stay away from open fields, tall objects and water.

A report suggested that it did not matter whether a person was standing up, squatting, or lying down when outside during a thunderstorm, because lightning can travel along the ground; this report suggested it was safest to be inside a solid structure or vehicle. Safety1325 East West HighwaySilver Spring, MD 20910Comments? EDMONDS, Wash. -- A Washington State Ferry was knocked out of service Saturday evening after it was struck by lightning, and repairs have kept it …

Because the ground has high impedance, the current "chooses" a better conductor, often a person's legs, passing through the body. [21] The smoke and mist expelled by a very large forest fire can cause electric charges, starting additional fires many kilometers downwind.

The chaff was devised to deal with the electrical manifestations of the storm from within, while the silver iodide salting technique was devised to deal with the mechanical forces of the storm. This occurrence is known as "A Bolt From the Blue";[26] lightning can strike up to 10 miles from a cloud. Most indoor lightning casualties and some outdoor casualties are due to conduction. A lightning rod (or lightning protector) is a metal strip or rod connected to earth through conductors and a grounding system, used to provide a preferred pathway to ground if lightning terminates on a structure.
