The April 4, 2010, El Mayor-Cucapah M7.2 quake in Baja California resulted in the area around the city of Calexico moving up to 31 inches (80 cms) to the southeast. I presume that this is the relative slip across a right-lateral fault system.
A team from NASA's Jet Propulsion Lab used combined airborne radar images from flights on Oct. 21, 2009, and April 13, 2010 to create interferograms that show the deformation.
