Tutorial
An earthquake occurs 7,375 km from a seismograph.
The P-waves arrive 12.2 minutes later. How fast is the
P-wave traveling (in km/s)?
If the lag time between P- and S-waves is 10.6 minutes,
how fast are the S-waves traveling (in km/s)?
Using the shadow of S-waves you determine that the
radius of the core is 55% of the Earth's 6,378-km radius.
How many kilometers from the surface is this (in km)?
Part 1 of 3
To calculate how fast the P-waves are traveling, we
need to divide the distance the waves travel by the
time.
