Document Summary
Japan - march 11, 2011: 235 billion dollars!!!!!!!!! Dramatic: destruction of buildings, injuries, fatalities, tsunamies . Disturbing: what appears static and solid is moving violently. Depth fault type the likely hazards/problems that would result there. the risks. Understand the primary earthquake hazards and be able to use that to your advantage. Understand the earthquake situation in the vancouver area (or all of cascadia) Relate the layering of the earth (composition and strength) to the operation of plate tectonics and earthquakes. Describe the differences between crust and mantle, lithosphere, and asthenosphere. Describe the typical ridgecrest spreading rate - and therefore the typical convergence or subduction rate. Describe the global distribution of earthquakes and how the frequency of earthquakes changes with magnitude. Explain how any rock can be brittle and elastic and plastic (even all at the same time) Elastic still a solid but bends and things. Tectonic plates are made of solid crust and solid upper part of mantle.
