Static stress change models
Static stress change models for known or hypothesized faults in the Hispaniola and Puerto Rico subduction segments due to (a) slip on a patch of the Puerto Rico subduction zone, and (b) slip on a patch of the Hispaniola subduction zone. An open arrow denotes slip direction and the patches are marked by dashed rectangles. Heavy black lines are simplified fault traces. Colored-filled rectangles below the fault traces represent the Coulomb stress change on vertical fault planes associated with these fault traces assuming left-lateral strike slip motion on the fault planes. Earthquakes used to determine average slip parameters are shown as "beach balls".
