Which of the seismic waves travels the fastest?

• Instant Wave

• Surface Wave

• Secondary Wave

• Primary Wave

What method do seismologists use in locating an epicenter?

• Focus Group Discussion

• Interview

• Observation

• Triangulation

To determine the lag time, simply get the _____________________ of S-wave and P-wave.

As the distance from the epicenter decreases, the time interval between the arrival of the P-waves and the S-waves on the seismograph will _________________

• decrease

• increase

• remain the same

• zero

Waves can be detected by earthquake monitoring instruments called ________________ .
