The most common type of lightning injury occurs when the lightning strikes the ground and the current is passed into the victim. Direct strikes are rare. The lifetime risk of being struck by lightning in the United States is approximately 1 in 14,600....
A direct lightning strike occurs when all the lightning’s energy is directed through the body or over the body on the skin. An indirect lightning strike can happen two different ways. The first way is through a ground current. These occur when lightning strikes an object or the ground and...
strokes (classical transmission line (TL) model), (2) ground-initiated return strokes including possible reflections at ground level, (3) tall strike objects for which the current's zero-to-peak time is smaller than the travel time along the object, and (4) electrically short strike objects....
A.During a lightning strike the diameter of the channel the electrons follow is considerably enlarged beyond a few centimeters. B.A building is unlikely to be hit by lightning unless it is at least 100 meters tall. C.A building is hit by a lightning strike because the building itself has ...
lightning strike to travel down your back and hopefully have less damage to vital organs. Lightning travels through the ground from the point of impact in random tendrils similar to tree roots. The smaller your footprint, the less chance there is of you being shocked from a nearby strike. ...

[5, 6] Survivors may also show signs of blast injury, including shrapnel, since being close to a lightning strike is similar to being within the blast range of an explosion; the thermodynamics within 10 m of lightning is equivalent to approximately a 10-lb (4.5-kg) TNT explosive. A 10-...
It is stipulated in this study that if the ground strike density in the vicinity of the structure is no more than 5% of the average density, then the structure has a sufficient protective effect on this area. The data indicate that there is a positive correlation between the protection ...
strike leading to neutral current flowing to earth via a remote ground, this can have destructive effects on sensitive equipment. Lightning strikes which hit overhead lines often cause ‘flashovers’ to neighbouring conductors as the insulators break-down, the strike will therefore not only consist ...
When the first strike occurs, current flows in an attempt to neutralize the charge separation. This requires that the current associated with the energy in the other stepped leaders also flows to the ground. The electrons in the other stepped leaders, being free to move, flow through the leade...
