20.1. Classification of Earthquakes Based on Causes

Try these first

1. 1.

   What type of earthquake is caused by volcanic activity?

   Hint

   Think of earthquakes that may precede eruptions.

2. 2.

   What do we call the earthquakes caused by human activities such as fracking?

   Hint

   This term relates to human actions affecting geological stability.

3. 3.

   What is the main cause of tectonic earthquakes?

   • Volcanic activity
   • Movement of plates
   • Human activities

   Hint

   Think about what drives the Earth's geology.

4. 4.

   True or False: Induced seismicity is a natural phenomenon.

   • True
   • False

   Hint

   Consider whether humans play a role in this type of earthquake.

5. 5.

   Analyze the recent earthquakes database and identify examples of induced seismicity. Discuss their implications on urban development.

   Hint

   Look into recent news articles on fracking activities.

6. 6.

   Evaluate how tectonic earthquake patterns inform civil engineers about designing safe structures. Give specific examples.

   Hint

   Think of notable fault lines and engineering adaptations.
