23.11.1. Stick-Slip Behavior

Try these first

1. 1.

   What is the stick phase in stick-slip behavior?

   Hint

   Think about how energy builds up before being released.

2. 2.

   What happens in the slip phase?

   Hint

   What occurs when pressure overcomes resistance?

3. 3.

   What phase describes the accumulation of elastic strain in rocks?

   • Stick Phase
   • Slip Phase
   • Creeping Phase

   Hint

   Remember the analogy of energy building up before being released.

4. 4.

   True or False: Locked faults release energy gradually without significant earthquakes.

   • True
   • False

   Hint

   Focus on what happens during a lock versus creep scenario.

5. 5.

   A locked fault accumulates 500 units of strain before slipping. Calculate the energy released during the subsequent earthquake if 1 unit of strain equates to 2 units of energy.

   Hint

   Use the relation between strain and energy for your calculations.

6. 6.

   If a creeping fault is experiencing continuous movement releasing energy at a rate of 10 units per year, how much energy will be released over 15 years?

   Hint

   Consider this as a simple multiplication of the energy release rate.
