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.

Advances in glacier ice flow
mapping using repeat
satellite images, and later using interferometric synthetic aperture
radar SAR methods, facilitated the mass budget approach, although this still requires an estimate of snow input and a cross-section of the glacier as it flows out from the continent and becomes floating ice.
