Lightning Strike (cont.)

Lightning Strike Causes

Injury from a lightning strike may occur in any of these ways:

  • Direct strike: Lightning directly strikes a person.

  • Contact strike: A person is touching an object (such as a tree or pole) that has been struck by lightning.

  • Side splash: Lightning jumps from the primary strike object on its way to the ground.

  • Ground strike: Lightning strikes the ground and the current spreads out in a circle from that spot.

  • Blunt injury: A person is thrown violently from the lightning strike or from the explosive force that occurs as surrounding air is superheated and rapidly cooled.

  • Upward streamer: When a low-energy electrical charge streams upward to meet a downward leader, it may carry enough current to cause electrical injury even if it does not connect with the downward current to complete the lightning strike.
