Our transcription: With an understanding of the geologic structure of the fault zone, geophysicists set up other experiments to measure movement along the fault.
One device that can detect movement in a very specific localized area is called a "creep meter."
Each creep meter consists of a wire stretched across the fault between two fixed points.
Whenever the fault slips, the length of wire between the two points changes recording the amount of motion along the fault.
Although the creep meter only covers about a ten meter zone, it runs at very high sensitivity and continuously monitors any fault motion at the surface.
