Earthquakes (Using ESRT P.11)

A p-wave traveled for 3200 km to reach a seismic station. How long had it traveled for?

• 1 min 20 sec

• 4 min 50 sec

• 10 min 40 sec

• 6 min 00 sec

If the p-waves arrive at 03:22:43 am and the s-waves arrive at 03:29:47 am, what is the time difference between their arrivals?

• 14 min 7 sec

• 7 min 04 sec

• 10 min 00 sec

• 15 min 20 sec

A seismic station is 2,400 KM from the epicenter of an earthquake. Approximately how long did it take the P-wave to arrive?

• 8 minutes 20 seconds

• 1 minute 20 seconds

• 4 minutes 40 seconds

• 5 minutes 40 seconds

Answer explanation

on the bottom of the chart, go to a distance of 2,400. Go up unitl you hit the P-wave line and look to the left to get the p wave travel time.

A seismic station is 4,600 KM from the epicenter, how much time is necessary for the first S-wave to arrive?

• 14 minutes

• 7 minutes 40 seconds

• 8 minutes 20 seconds

• 4 minutes 40 seconds

Answer explanation

ESRT 11

Go to a distance of 4,600 KM.

Follow up until you hit the S-wave line.

Look to the left and determine the minutes.
