Homework Answers
Shear
Because S-wave is also called a Shear wave based on their propagation of energy while passing through rock. The shear wave is generated due to a shearing motion on the source region and the particle motion is either horizontal (SH wave) or perpendicular (SV wave) to the direction of the wave motion.

002 10.0 points Earthquakes produce two kinds of seismic waves: he longitudinal primary waves (called P waves) and the transverse secondary waves (called S waves). Both S waves and P waves travel through Earth's crust and mantle, but at different speeds; the P waves are always faster than the S waves, but their exact speeds depend on depth and location. For the pur- pose of this exercise, we assume the P wave's speed to be 8380 m/s while the S...

3. Earthquake warning system A typical earthquake produces two types of seismic waves. P ("primary" seismic waves are longitudinal waves that move through the earth's upper crust with speed anywhere from 3 km/s to 5 km/s (the exact speed depends on the local composition of the earth's crust). S ("secondary") waves are transverse waves that move slower than P waves. The S-wave speed is typically about 60% less than the P-wave speed in any given material. The map below shows...

Question 6 (3 points) An earthquake emits both S-waves and P-waves which travel at different speeds through the earth. An S-wave travels at 5000 m/s and a P-wave travels at 9000 m/s. If S-waves are received at a seismic station one minute after a P-wave arrives, then how far away is the earthquake center? 88.9 km 240 km 480 km 675 km 1200 km

Suppose that p- and s-waves traveled in straight lines through the Earth (in fact, they don't, but we will make this approximation for this problem). Also suppose that the angular distance from the epicenter (location of the earthquake) on the Earth's spherical surface to the location on the surface beyond which no s-waves can be observed from an earthquake (the angle between the earthquake epicenter and the s shadow zone) is 120 degrees (i.e., the two points are located 1/3...

QUESTION 2 Earthquakes produce several types of shock waves, two of which are called S and P waves. P waves travel at about 6.5 km/s, and S waves travel at about 3.5 km/s. The delay in arrival times between P waves and S waves provides from the measurement station. If a station records a delay of 33 s, how far from the station was the earthquake (ín kilometers? Use two significant figures in your answer. information about how far away...
