Question

An earthquake occurs 6,875 km from a seismograph. The P-waves arrive 11.6 minutes later. How fast is the P-wave traveling (in km/s)?

If the lag time between P- and S-waves is 10.8 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)?

To calculate how fast the P-waves are traveling, we need to divide the distance the waves travel by the time.

According to the infographic above a recent magnitude 5.4 Earthquake was recorded. Earthquakes represent a release of energy as a result of the earth's tectonic plates. a) Determine the amount of energy release in ergs. b) Determine the energy release in Joules. ( Hint use the earthquake formula M = 2/3 log (E/ 10^11.8); where M is the earthquake magnitude and E is the energy of the earthquake in ergs (recall 1 erg = 10^-7 Joules)). c) Using the earthquake magnitude scale below to qualitatively categorize (was it Minor, Light, Moderate, Strong, Major or Great) and describe the earthquake (what kind of damage is expected from a magnitude 5.4 earthquake).
