Document Summary
12 cont: different types of waves, body waves, surface waves, surface waves: slow waves, verticle: compress materials, horizontal: shears materials, p-waves compress materials; fastest, s-wave: shears materials; doesn"t travel through liquid. How seismic waves are recorded: basic seismometer, modern seismometer (in ground, seismogram. How do we determine the location of an earthquake: recorded by seismic network, select earthquake records and find p and s waves, calc distance from p-s time, triangulate the epicenter. Measuring the size of an earthquake: for local magnitude (richter) measures s-wave, energy released in an earthquake, connect amp and distance on plot. Damage from eqs: rupture, landslide, structural damage, bridge failure, liquification of fill, tsunami, aftershock, fire, explosion. New madrid fault zone: not active, however stresses from the west can reactivate it. Haiti 2010 eq: mag 7on strike-slip fault, port-au-prince, many deaths 200,000, very poor consruction. New zealand 2010/2011: mag 7. 1 minor damage no deaths 2010, mag 6. 3 200 killed 2011.
