35.5.4. Fault Type and Depth

Try these first

1. 1.

   What type of fault generally produces higher Peak Ground Acceleration?

   Hint

   Think about the force exerted on the rocks.

2. 2.

   True or False: Deeper faults generally cause more intense shaking.

   Hint

   Consider the proximity to the Earth's surface.

3. 3.

   Which type of fault is most likely to produce higher PGAs?

   • Normal
   • Thrust
   • Strike-Slip

   Hint

   Consider how each fault type behaves.

4. 4.

   True or False: Shallow faults typically lead to less intense ground shaking.

   • True
   • False

   Hint

   Reflect on how energy travels through layers of the Earth.

5. 5.

   Consider a scenario with a partially submerged thrust fault at a depth of 1 km and another at 5 km. Analyze how PGAs would differ between these two scenarios when subjected to the same earthquake forces.

   Hint

   Evaluate the energy transformation and dissipation over distance.

6. 6.

   If you were assessing a location with high PGAs from both a thrust fault and a significant directivity effect, what structural strategies would you propose?

   Hint

   Think about how structures can adapt to shaking.
