19.4. Seismographs and Seismometers

Try these first

1. 1.

   What is a seismograph?

   Hint

   Think about how we measure earthquakes.

2. 2.

   What key measurements can seismographs provide?

   Hint

   Think of the three main aspects of ground motion.

3. 3.

   What type of data do seismographs provide?

   • Only ground acceleration
   • Ground motion data
   • Only visual observations

   Hint

   Think about the full range of measurements.

4. 4.

   True or False: Strong-motion seismographs are designed for low-intensity earthquakes.

   • True
   • False

   Hint

   Consider their purpose during significant earthquakes.

5. 5.

   You have a seismograph recording ground acceleration during an earthquake. Discuss how you would interpret the recorded data and what it might mean for civil engineering.

   Hint

   Think of how structure adjustments might help prevent damage.

6. 6.

   Given a scenario where a strong-motion seismograph recorded unusually high velocities, explain the implications for urban planning.

   Hint

   Consider which areas in a city might require more robust designs.
