epicenter
intensity
magnitude
You were provided with data showing the arrival time of the P-wave and S-wave recorded from three seismic stations. Which of these can you possibly determine?
The damage at the focus
The distance to the earthquake
The intensity of the earthquake
The location of the epicenter
From the seismogram, the distance to the epicenter can be determined by measuring
The arrival time of surface wave
The difference in the arrival times of the P and S-waves
The ratio of the amplitude of the largest P and S-waves
The speed of the surface waves
