Geology 101, Fall 2006 Name: Assignment 5: Earthquakes and solid Earth geophysics Due Wednesday, November 8 at noon Distinguish the following terms: focus (hypocenter) vs. epicenter P-seismic wave vs. S-seismic wave Love waves vs. Rayleigh waves vertical vs. horizontal acceleration during an earthquake Richter magnitude scale vs. Modified Mercalli intensity scale displacement vs post-earthquake creep seiche vs. tsunami Mohorovicic discontinuity (Moho) vs. Benioff-Wadati zoneDoes the ground literally “turn to liquid” during liquefaction in an earthquake? What actually happens? Where did liquefaction occur during the February 28, 2001 Nisqually earthquake? How are earthquakes due to fault or plate motion different from earthquakes that occur when magma moves underneath a volcano? What does the “S-wave shadow” tell us about the Earth’s interior structure? What is seismic wave refraction, and what do geophysicists use this
