Slip rate on a fault, measured in millimetres per year, indicates

  • A.the rate at which the fault is eroding
  • B.how quickly strain accumulates on it
  • C.how fast seismic waves travel along it
  • D.the speed at which rupture propagates

Answer: B

Correct answer: how quickly strain accumulates on it

Slip rate is the long-term average rate at which the two sides of a fault move past each other, established from offset geological features or from geodetic measurement. It sets the pace of the earthquake cycle: a fault slipping at 20 mm a year accumulates a given slip deficit ten times faster than one at 2 mm a year, and so produces its earthquakes ten times as often.
