The authors used two ERS1 synthetic-aperture radar images to generate the interferogram for the M5.4 Landers aftershock, which provide good estimate of the earthquake location and focal mechanism.

SAR images spanning the period of seven years between Landers and Hector Mine earthquakes are used to generate interferometry measurement of surface deformation. The decay time of the measured postseismic deformation is several years. The deformation is modeled and interpreted with viscoelastic and poroelastic relaxation.

In a two-step inversion for kinematic rupture of Landers earthquake, InSAR and GPS measurement were first used to constrain the slip distribution. Then, seismic strong motion data were used to invert the temporal process of the earthquake rupture. They concluded that the Landers earthquake, as shown by the slip distribution and rupture velocity as well, is far from uniform and constant rupture.

The authors used InSAR data after the Hector Mine earthquake, and found postseismic deformation of several centimeters, with clear subsidence and uplift. The postseismic relaxation time, as revealed by temporal InSAR results, is about 135 days, same to that of the Landers quake.

Both InSAR and campaign GPS observations from 55 stations were used to constrain the fault slip of Hector Mine earthquake.

An interferogram was constructed by combining topography with SAR data before and after the Landers earthquake. The observed changes agree well with displace measurement by surveying, but with a higher spatial resolution and precision.

GPS did not have good measurements of postseismic deformation for the Landers earthquake, due to the sparse location. SAR interferograms provide better spatial coverage and were used to capture the postseismic deformation pattern.

This review paper introduced the principles and limitations and InSAR measurements, how to construct, improve and interpret interferograms. Finally, various geophysical applications of InSAR measurements are provided and discussed.

The1992 M7.1 Cape Mendocino earthquake occurred at north of the Mendocino Triple Junction, and the slip generated two magnitude 6.6 earthquakes and tsunami. The seismicity in this region might continue.

The study used GPS and InSAR during a three-year period to measure the postseismic deformation after the Landers earthquake. These measurements are used to investigate the deformation mechanism to explain the high transient velocities after this earthquake.

This research use InSAR to image the coseismic deformation of the Landers earthquake. Also, a technique was introduced to examine the short-wavelength deformation from the interferogram.

Both an ascending and descending SAR interferograms were used to constrain fault slip for the Hector Mine earthquake. The two interferograms from both ascending and descending images were required to accurately estimate the surface slip. Both interferograms were well explained by a simple uniform slip model.

The authors used both SAR interferograms and GPS measurements to investigate the coseismic static deformation of the Hector Mine earthquake. These geodetic measurements were inverted to estimate the fault geometry and slip distribution. Their model agreed with both field mapping results and seismic models.

The focal mechanism of the intraslab earthquakes in Cascadia subduction zone were investigated, and the intraslab stress orientations were then determined for several subareas. The results show segmentations for intraslab seismicity and stress status in Cascadia subduction zone.
