Document Summary
Speed in open water similar to that of a jet plane (500mph) Energy stored in waves deeply as it gets closer to shore the wave height rises. Tohoku eq in japan 2011 reached california after 9 hours. Dart pressure sensors to determine wave height that signal the gps buoys. Spreading = divergent margins (we have all three different kinds of plate-plate interaction) Seismically most active region in california is mendocino triple junction. North american plate, juan de fuca plate, pacific plate meet. Cascadia has largest eq hazard in the us: potentiall m>9. Large eqs recur on san andreas about every 150 years. San andreas faults splits into several faults: 75km long, along the foot of east bay hills. The great san francisco earthquake - april 18, 1906 m=7. 8. Damage not caused by earthquake; damage caused by fire that was brought about by earthquake. Loma prieta earthquake - october 17, 1989 m=7. 0. Damaged area: santa cruz, oakland, marina district.
