13.) Seismic waves are transverse waves that travel only on Earth's surface.
a. true
b. false
Earthquakes produce several types of shock waves. The most well-known are the P-waves (P for primary or pressure) and the S-waves (S for secondary or shear). In the earth's crust, the P-waves travel at around 6.5 km/skm/s while the S-waves move at about 3.5 km/skm/s. The actual speeds vary depending on the type of material they are going through. The time delay between the arrival of these two waves at a seismic recording station tells geologists how far away the earthquake occurred.
If the time delay is 33 ss, how far from the seismic station did the earthquake occur?
