The slight branching redness traveling up this person's leg was created by current from a nearby lightning strike. A Lichtenberg figure (German: Lichtenberg-Figur ), or Lichtenberg dust figure , is a branching electric discharge that sometimes appears on the surface or in the interior of insulating materials .
Lightning-induced magnetic anomalies can be mapped in the ground, [121] [122] and analysis of magnetized materials can confirm lightning was the source of the magnetization [123] and provide an estimate of the peak current of the lightning discharge.
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.
The lightning may be too far away to discern individual flashes. Smooth channel lightning is an informal term referring to a type of cloud-to-ground lightning strike that has no visible branching and appears like a line with smooth curves as opposed to the jagged appearance of most lightning channels. They are a form of positive lightning ...
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]
The wealthier kids whose parents pay for the “Lightning Line” at the Slinky Dog Dash roller coaster at Disney World can pop on and move on. Regular guests are waiting an average of 88 minutes ...
Material properties (size, color, texture) of fulgurites vary widely, depending on the size of the lightning bolt and the composition and moisture content of the surface struck by lightning. Most natural fulgurites fall on a spectrum from white to black. Iron is a common impurity that can result in a deep brownish-green coloration.
