A locked segment of an active fault is one that is

  • A.permanently welded and incapable of slip
  • B.no longer subject to any tectonic stress
  • C.accumulating strain to be released later
  • D.sliding steadily and releasing strain as it goes

Answer: C

Correct answer: accumulating strain to be released later

Locked means held by friction, not permanently fixed: the plates continue to move, so strain builds in the rock around the locked patch and must eventually be released in an earthquake. This is why locked segments are the ones that concern hazard analysts, while segments that creep steadily release their strain harmlessly as they go.
