20.6. Reservoir-Induced Seismicity (RIS)

Try these first

1. 1.

   What does Reservoir-Induced Seismicity (RIS) refer to?

   Hint

   Think about how water weight affects the earth.

2. 2.

   Name one notable example of RIS.

   Hint

   Consider disasters linked to dams.

3. 3.

   What is Reservoir-Induced Seismicity?

   • Earthquakes caused by volcanoes
   • Earthquakes triggered by water reservoirs
   • Natural seismic activity

   Hint

   Think about how water influences the geology below it.

4. 4.

   True or False: Pore pressure can reduce friction on faults in a reservoir setting.

   • True
   • False

   Hint

   Pore pressure relates to the pressure of water in rocks.

5. 5.

   Evaluate the potential risks of building a new dam in an already seismically active area and propose measures to mitigate these risks.

   Hint

   Consider how existing seismic activity could interact with the added pressures from the reservoir.

6. 6.

   Create a risk assessment plan for an existing dam that has a history of reservoir-induced seismicity. What data would you collect, and what steps would you take?

   Hint

   Think about historical examples to guide your assessments.
