1950 km
Record your answer from Lab Exercise #1, Step 2, Question 4. What is the distance in kilometers between the seismic station and the epicenter?
3000 km
Record your answer from Lab Exercise #2, Step 1. What is the time lag for noted at the Seattle, Washington, seismic station?
65 seconds
Record your answer from Lab Exercise #2, Step 2. What is the distance between the Seattle seismic station and the earthquake's epicenter?

The epicenter of an earthquake is a point
on the earth's surface directly above the initial release of seismic energy
Record your answer from Lab Exercise #2, Step 12. What city is nearest to the epicenter?
Helena
Record your answer from Lab Exercise #1, Step 1, Question 3. What is the time lag (S-P) in hours:minutes:seconds?
00:04:10
Record your answer from Lab Exercise #1, Step 1, Question 1. What time in hours:minutes:seconds GMT did the P waves arrive?
01:49:00
Record your answer from Lab Exercise #1, Step 1, Question 2. What time in hours:minutes:seconds GMT did the S waves arrive?
01:53:10
Which of the following seismic waves is the last to arrive at a seismic station?
Love wave
Which of the following seismic waves has the same wave form as a sound wave?
P wave
Which of the following seismic waves is the first to arrive at a seismic station?
P wave
The following seismic waves are used to locate earthquake epicenters:
P waves and S waves.
The two kinds of body waves are
P waves and S waves.
Which of the following statements is correct?
P-wave amplitude and S-wave amplitude are about the same.
Which seismic wave vibrates side-to-side relative to its direction of travel?
S wave
To locate the epicenter of an earthquake, it takes
at least three seismic stations
Determining the distance along the earth's surface from a seismic station to the epicenter of an earthquake is based on the difference in arrival times between
the first P wave and the first S wave
The focus of an earthquake is a point
within the earth where the initial release of seismic energy occurs.
