Question 1.
What is the first seismic wave to arrive at a seismic station?
Show hintHide hint
Think of the 'P' in primary.
Question 2.
What does PGA stand for?
Show hintHide hint
What do you measure during an earthquake's ground shaking?
3Question 3.
What wave arrives first during an earthquake?
- P-wave
- S-wave
- Surface wave
Show hintHide hint
Remember: P stands for Primary.
4Question 4.
True or False: S-waves arrive before P-waves.
- True
- False
Show hintHide hint
Think about the order in which waves travel.
Question 5.
Given a seismogram with distinct P, S, and surface waves, draw and label the waveforms, and note the amplitude differences. Discuss how these would affect building designs in a seismically active area.
Show hintHide hint
Focus on the amplitude's effect on potential damage.
Question 6.
Using a hypothetical seismogram, identify the P-wave, S-wave, and surface wave, and calculate the time difference between their arrivals. Discuss how this information might be used in real-time earthquake warnings.
Show hintHide hint
Consider the speed of waves and the implications for safety.
