Step potential is the voltage across how much soil?

Explanation:
Step potential is the voltage difference between two points on the earth’s surface that are about one meter apart—the distance between your feet as you take a step away from a fault. This one-meter separation is used because it reflects the exposure a person has while stepping away, which is where hazardous current can flow through the soil from the fault to the person’s feet. So the voltage drop across roughly 1 meter of soil is the step potential. The other distances aren’t the standard measure for this concept, since they don’t represent the typical spacing between feet during a step.
