D17 Methodology for combining INSAR and CGPS for maximum benefits

An algorithm for estimating fault slip at depth from joint inversion of INSAR and GPS measurements has been validated on an earthquake in Turkey. Using Singular Value Decomposition, it is published as:

A similar approach has been applied to an earthquake in Iceland. Using simulated annealing, it will be submitted as:
