| Abstract | Costa Rica has been selected as one of the MARGINS SEIZE (Seismogenic Zone) “focus ” sites for intensive inter-disciplinary studies of the seismogenic zone (Figure 1). One of the goals of these studies is to accurately map the up-dip and down-dip limits of the seismogenic zone and the percentage of locking on the plate interface, and to understand the physical processes that control these parameters. The amount of “slip ” (long term plate motion) that is temporarily locked on the plate interface may be significantly less than the full plate con-vergence rate, may vary between subduc-tion zones, and probably varies with depth at all subduction zones. Thus, in addition to defining the “up-dip and down-dip limits”, we really seek to deter-mine the percentage of long term plate Figure 1.
