INTERFEROMETRICFRINGES (colored bands above) obtained from a sequence of radar scans bythe ERS-1 satellite (above, left) show the deformation of the ground caused byan earthquake near Landers, Calif., in 1992. Each cycle of interference colors(red through blue) represents an additional 28 millimeters of ground motion inthe direction of the satellite. The radar interference caused by the mountainousrelief of the area (black-and-white background) was removed to reveal thispattern of ground deformation.
