Seismogenic zone locking in Central America: Comparison of GPS-determined locking on the plate interface, well-located plate interface earthquakes (circles) recorded during our seismic network deployment, and rupture areas of past large earthquakes. Squares and dashed lines show original epicenter and rupture area, respectively, stars and solid lines show relocations, relative to better located 1990 event (black star). Offshore locked patch is up-dip of seismicity, and is less than rupture area of past large events. Image from the MARGINS 2008 Decadal Review research nugget.
