20.17.1. Natural Triggers

Try these first

1. 1.

   What is stress transfer?

   Hint

   Remember how one earthquake impacts another.

2. 2.

   How can landslides trigger earthquakes?

   Hint

   Think about sudden geological movements.

3. 3.

   What is Coulomb stress change?

   • Increased water pressure
   • Change in stress on a fault
   • Rising lava beneath the crust

   Hint

   It's related to how one earthquake affects another.

4. 4.

   True or False: Solar tidal forces have no impact on earthquake activity.

   • True
   • False

   Hint

   Consider if everything has influence.

5. 5.

   Given recent seismic activity in an area, assess the likelihood of future earthquakes based on stress transfer mechanics.

   Hint

   Review how stress changes and history correlate.

6. 6.

   Predict potential earthquake implications based on a newly discovered underwater landslide.

   Hint

   Consider the local geological makeup and prior seismic activity.
