“…While the earliest InSAR interseismic studies were based on small stacks of interferograms [e.g., Wright et al, 2001], current such studies commonly involve analysis of hundreds of interferograms spanning several overlapping tracks and across regions hundreds of kilometers wide [e.g., Jolivet et al, 2012;Kaneko et al, 2013;Tong et al, 2013;Cavalié and Jónsson, 2014]. New SAR missions such as Sentinel-1, with regular acquisitions and frequent revisit times, will enable InSAR to be used to map crustal deformation on the global scale, and to be incorporated into maps of global strain rate, which are currently based on GPS measurements alone [e.g., Kreemer et al, 2003].…”
