Earthquakes in urban centers are capable of causing enormous damage. During the last decade the availability of space-derived crustal deformation data has transformed the field of solid earth geophysics and more specifically, the study of the deformation of the Earth's crust and earthquakes. For example, Synthetic Aperture Radar data are revealing spatially dense information on how the earth's crust deforms and how faults interact with each other. Sophisticated models run on high-performance computers provide insight into the behavior of earthquake fault systems. This presentation will focus on the development of space-based techniques that make it possible to measure quiet motions associated with plate tectonics and the earthquake cycle. These measurements are providing an unprecedented look at this cycle and are revolutionizing our understanding of earthquake processes and fault interactions.
