3. describe the 3 general parts of the cascadia subduction zone where earthquakes occur. a. - b. - c. - 4. how big (magnitude) can “subduction-zone" earthquakes be, and how often do they occur along the cascadia subduction zone? (2) 6. dr draw a cross-sectional (vertical slice into earth's interior, or side view) diagram showing the subduction zone and the 3 general locations of earthquakes. label each of the 3 earthquake locations with a, b or c to correspond to the 3 locations that you described in question #3. in addition to the earthquake locations, label the overriding plate and the subducting plate and the trench. indicate the relative motion between the 2 plates and indicate whether each plate is oceanic or continental along the boundary. you can use the diagram(s) from the article for reference, but do not copy them. create your own cross-section; you do not need to include a map-view - just the profile/side-view. (3) 7. if you hear that there was a magnitude 6 earthquake with a focus depth of about 10 km (6 mile), at which of the 3 general locations do you think it was generated? explain your reasoning. 8. how is it possible to know the timing of the quake if it occurred long before the introduction of seismographs or any written record? summarize 2 lines of evidence given in this report. be sure to describe/explain how this evidence records the earthquake timing and magnitude.
