Textbook Question
Textbook Question(II) P and S waves from an earthquake travel at different speeds, and this difference helps locate the earthquake “epicenter” (where the slippage took place).
(a) Assuming typical speeds of 8.5 km/s and 5.5 km/s for P and S waves, respectively, how far away did the earthquake occur if a particular seismic station detects the arrival of these two types of waves 1.5 min apart?
