Earthquake Triangulation

You were provided with data showing the arrival time of the P and

S-waves 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 wave

It is an elastic from the earth produced by an earthquake or other means.

• Microwaves

• Radiowaves

• Seismic Waves

• All of the Above
