  1. Loma Prieta addition Fitting vertical displacement data

  2. Leveling data from Marshall and Segall, 1996: Coseismic vertical displacements http://pubs.usgs.gov/pp/pp1550/pp1550a/ Just looking at the dip slip component, what is the best fitting fault geometry and slip? Extracted displacement profile

  3. dip = 120; %want it to dip to the west b = 1; %burger's vector %fault upper tip (remember that positive is down; xi, zeta) xi_upper = 21250; zeta_upper = 3000; down_dip_length=9000;

  4. dip = 120; %want it to dip to the west b = 2; %burger's vector %fault upper tip (remember that positive is down; xi, zeta) xi_upper = 21250; zeta_upper = 3000; down_dip_length=9000;

  5. dip = 120; %want it to dip to the west b = 2; %burger's vector %fault upper tip (remember that positive is down; xi, zeta) xi_upper = 21250; zeta_upper = 1000; down_dip_length=9000;

  6. dip = 120; %want it to dip to the west b = 2; %burger's vector %fault upper tip (remember that positive is down; xi, zeta) xi_upper = 21250; zeta_upper = 5000; down_dip_length=9000;

  7. dip = 90; %want it to dip to the west b = 1.5; %burger's vector %fault upper tip (remember that positive is down; xi, zeta) xi_upper = 21250; zeta_upper = 3000; down_dip_length=9000;

  8. dip = 150; %want it to dip to the west b = 1.5; %burger's vector %fault upper tip (remember that positive is down; xi, zeta) xi_upper = 21250; zeta_upper = 3000; down_dip_length=9000;

  9. Best fit dip = 119.5; %want it to dip to the west b = 1.5; %burger's vector %fault upper tip (remember that positive is down; xi, zeta) xi_upper = 21250; zeta_upper = 3000; down_dip_length=9000;

  10. 2D grid search Slip Best fit Dip

  11. 2D error surface

  12. Best fit This is troubling dip = 119.5; %want it to dip to the west b = 1.5; %burger's vector %fault upper tip (remember that positive is down; xi, zeta) xi_upper = 21250; zeta_upper = 3000; down_dip_length=9000;
