Chapter 4—Forecasting and mitigating earthquakes Methods of forecasting EQs First establish pattern of movement on fault Then look for seismic gaps or EQ migration Minimizing EQ damage Structural design: diagonal supports, reinforced steel bracing, foundation bolts, adequate building spacing, no weak floors, wooden/steel frames, base isolation Land use planning EQ preparedness Chapter 5 -- Tsunami Mechanisms that generate tsunami Tsunami characteristics onshore Tsunami Hazard Mitigation Land use planning Warning systems Surviving a tsunami Future Giant Tsunami—where can we expect them? Cause of the 2004 Sumatra tsunami Chapter 6 – Magma and Volcanism Generation of magmas (increase T, lower P, add water to mantle) Key properties of magma that control the style/magnitude of eruption (the three V’s) Controls and classes of magma/lava chemical composition (basalt, andesite, rhyolite)
