3b. Seismology and Focal Mechanism On the Supplemental document to make a sketch’s of the three earthquake focal mechanisms that you would expect from an earthquake that occurred at each of the three locations (Stars A, B, and C) on the tectonic map of New Zealand. (Hint: the teeth (black triangles) on the plate boundaries are on the over-riding plate of a subduction zone and there is NO Oblique movement) (a) Sketch the focal mechanism for each of the three locations (A–C). Use your protractor ruler to get the orientations a close as possible. (NO oblique slip) USE YOUR PROTRACTOR to determine the precise strike of the plate boundaries and for plotting on the Supplemental Document. (include all labeling as in the Assingments (i.e., arrows and shading). (b) Choose the correct focal mechanism solution by write the approximate strike (azimuth and quadrant) and the dip of the fault that the earthquake most likely occurred on and include an arrow pointing to the selected fault plane.
