But Avouac, Ampuero, and their colleagues used satellite Synthetic
Aperture Radar data and a technique called back projection that takes advantage of the dense arrays of seismic stations in the United States, Europe, and Australia to track the progression of the earthquake, and found that it was quite contained at depth.

Using
data from Global Positioning System (GPS) stations and Interferometric Synthetic
Aperture Radar (InSAR) images collected during successive satellite fly - overs, ASU researchers were able to measure changes in surface elevation during a time period spanning the main Gorkha event, and several major aftershocks, with centimeter accuracy.
The UC Berkeley team used 19 years of satellite
data to map ground deformation using interferometric synthetic
aperture radar (InSAR) and measure creep along the southern end of the Hayward Fault, and found, surprisingly, that the creep didn't stop south of Fremont, the presumed southern end of the fault, but continued as far as the Calaveras Fault.
Finnish Meteorological Institute has been doing estimates of two essential sea ice parameters — namely, sea ice concentration (SIC) and sea ice thickness (SIT)-- for the Bohai Sea using a combination of a thermodynamic sea ice model and Earth observation (EO)
data from synthetic
aperture radar (SAR) and microwave radiometer.
A synthetic
aperture radar or equivalent capability is also needed in the production of the sea - ice climate
data record for validation of sea ice concentration and edge.
