Earthquakes, Day 2 Let’s learn some more . . .
Types of Seismic waves • What do we know about P-Waves? • What do we know about S-Waves? • What do we know about Surface Waves?
Types of faults • Normal Fault • Thrust Fault • Strike-Slip Fault
More vocabulary • Epicenter • Focus
Practice problems • In groups of 2, get one computer. • Open the “Dynamic Planet” map from the T-Drive. • You’ll also need a calculator and some paper
Math problem #1 • Suppose an earthquake occurs in Reykjavik, Iceland. • What type of fault probably caused this earthquake? • How long will it take for the P-Waves, S-Waves, and Surface Waves to be detected by a seismograph at KU?
Math problem #2 • Suppose an earthquake occurs in Port au Prince, Haiti. • What type of fault probably caused this earthquake? • What will be the gap between the arrival of the P-Waves and S-Waves on a seismograph in Lawrence, Ks.? (What’s the difference in the arrival times?)
Math problem #3 • Suppose an earthquake is recorded on a seismograph at KU. • The time gap between the arrival of the P-Waves and S-Waves is 45 seconds. • How far away was the epicenter of the earthquake? • Give your answer in miles. This one is very difficult:{)
