22.14. Tectonics and Tsunamigenic Earthquakes

Try these first

1. 1.

   What is a subduction zone?

   Hint

   Think of how tectonic plates interact.

2. 2.

   Define tsunamigenic earthquakes.

   Hint

   Remember the link between earthquakes and tsunami creation.

3. 3.

   What causes tsunamis during subduction events?

   • Vertical displacement of the seafloor
   • Landslides
   • Volcanic eruptions

   Hint

   Think about the direct impact of earthquakes on water bodies.

4. 4.

   True or False: All earthquakes generate tsunamis.

   • True
   • False

   Hint

   Consider the conditions necessary for tsunami formation.

5. 5.

   Evaluate the potential socio-economic impacts of a tsunami generated by a megathrust earthquake on coastal communities.

   Hint

   Consider both immediate impact and long-term recovery.

6. 6.

   Given historical data of tsunami occurrences, propose a plan for an early warning system in a tsunami-prone coastal region.

   Hint

   Think about how technology can be combined with community resources.
