Document Summary
Where the ground shakes where i am (seismic waves) The ground breaks along a fault (seismic source) Pacific rim of fire: a ring of subduction zones. Evidence of plate tectonics: continental drift, coastlines of different continents fit together. Mantel material that is hot between the two plates. Can get them on land too: strike-slip boundaries / transform. Angles that define faults (know that they exist!) Strike: angle between the north line and the face of the line. Rake: angle of which the actual movement takes place (direction) Dip: angle of the fault plate itself from the surface. Alaska is most active state: most active subduction zones in us. New madrid fault zone: failed divergent plate boundary several hundred million years ago, 1811-1812 sequence. Waste water injection leaving it there: oklahoma. Fracking does cause eq, but waste water injection does it more. Mendocino region of california: boundary of 3 tectonic plates.
