2. Fоcаl Mechаnism Plоtting with Stereоnet: [10pts Totаl] Using the stereonet and tracing paper of the stereonet with the labeled focal mechanism, and the supplemental document to the link provided with this question. (a) [6pts] Plot the two potential fault plane solutions to create the focal mechanism for the 2011 magnitude 9.0 Tohoku, Japan subduction zone earthquake. Be sure to shade the appropriate quadrants. Best Double Couple: Principal strain axes: Fault plane 1: Strike=193 Dip=14 W Fault plane 2: Strike=032 Dip=76 E (b) [1pts] Use your knowledge of faulting and location of Japan on the Ring of Fire to LABEL which of the fault plane solution is most likely the correct solution (fault plane). (c) [2pts] If there is any oblique movement on the fault plane you selected add arrows to the stereonet signifying the sense of displacement on the correct plane (b above). (d) [1pts] Lightly shade the appropriate regions of the focal mechanism to show compressional and dilatational fields. (e) (2pts) What type of fault was responsible for the Tohoku earthquake? Be sure to include a full characterization of the sense of slip including any oblique component.
