In the U.S., many lightning deaths and injuries are related to ground current. Most cloud-to-ground strikes begin near the lower portion of the cloud. In humans, the risk of a lightning death or injury increases for a person lying on the ground because the greatest distance between contact points (usually between the head and feet) is greater than the distance of the contact points (2 feet) if the person was standing up. Therefore, we know the most about cloud-to-ground lightning. Farm animals have a long span between their front and back legs making them more vulnerable to ground current from a nearby lightning strike. Triggered lightning starts at the 'ground,' which in this case may mean the top of a tower, and travels upward into the cloud.' NOAA adds that '. The threat of a fatal incident is affected by the distance between contact points with the ground and also the orientation of those contact points with respect to the lightning strike and discharge path. Furthermore, the damage done by the lightning bolts is considered projectile damage (instead of melee), therefore any Strength bonus does not apply. Ground current is responsible for killing many farm animals on a yearly basis.
This creates a dangerous and potentially deadly ground current near the lightning strike.
When lightning strikes the ground or an object on the ground, the discharge occurs in and along the ground surface (not deep into the ground).
