Working With Seismic Waves

The distance from Albany, New York, to the epicenter of an earthquake is 5600 km. Approximately how much longer did it take for the S-wave to arrive at Albany than the P-wave?

• 4 minutes and 20 seconds

• 7 minutes and 10 seconds

• 9 minutes and 0 seconds

• 16 minutes and 10 seconds

A seismic station 4000 kilometers from the epicenter of an earthquake records the arrival time of the first P-wave at 10:00:00. At what time did the first S-wave arrive at this station?

• 09:55:00

• 10:05:40

• 10:07:05

• 10:12:40

An earthquake's P-wave arrived at a seismograph station at 02 hours 40 minutes 00 seconds. The earthquake's S-wave arrived at the same station 2 minutes later. What is the approximate distance from the seismograph station to the epicenter of the earthquake?

• 1100 km

• 2400 km

• 3100 km

• 400 km

A seismograph station recorded the arrival of the first P-wave at 7:32 pm from an earthquake that occurred 4000 kilometers away. What time was it at the station when the earthquake occurred?

• 7:20 pm

• 7:25 pm

• 7:32 pm

• 7:39 pm

The difference in seismic station arrival times helps scientists determine the

• amount of damage caused by an earthquake

• intensity of an earthquake

• distance to the epicenter of an earthquake

• time of occurence of the next earthquake

Model A best represents the motion of earthquake waves called

• P waves (compressional waves) that travel faster than S-waves (shear waves) shown in model B.

• P-waves (compressional waves) that travel slower than S-waves (shear waves) shown in model B.

• S-waves (shear waves) that travel faster than P-waves (compression waves) shown in model B.

• S-waves (shear waves) that travel slower than P-waves (compressional waves) shown in model B.
