27. Seismogram

Try these first

1. 1.

   What does a seismogram record?

   Hint

   Think about what instruments measure during seismic events.

2. 2.

   Name the two types of seismograms.

   Hint

   Consider the evolution of technology as a clue.

3. 3.

   What do seismographs record?

   • Wind patterns
   • Ground motion
   • Temperature changes

   Hint

   Think about what natural disasters they are used to measure.

4. 4.

   True or False: S-waves travel faster than P-waves.

   • True
   • False

   Hint

   Recall the order of wave arrivals.

5. 5.

   Analyze a real seismogram and identify P-waves, S-waves, and surface waves. Discuss the significance of each wave in terms of potential structural impact.

   Hint

   Look for the order and amplitude of waves in the seismogram.

6. 6.

   Given the amplitude of a recorded S-wave is significantly larger than a P-wave, discuss the implications it has on structural design in earthquake-prone regions.

   Hint

   Consider how wave height correlates with damage.
