Challenge Problems
Push your limits with advanced challenges
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.
💡 Hint: Focus on the amplitude's effect on potential damage.
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.
💡 Hint: Consider the speed of waves and the implications for safety.
