WInSAR is a consortium of scientists engaged in radar remote sensing research and education, with major emphasis on InSAR applications in the western part of North America. WInSAR is hosted by UNAVCO, and both organizations are non-profit, membership-governed groups funded by the National Aeronautics and Space Administration, the U.S. Geological Survey and the National Science Foundation. We present here a summary of recent results by WInSAR scientists that have been enabled by the availability of ERS and Envisat data. In particular, we will present results on: (1) Strain accumulation and release along the diffuse plate boundary, including the San Andreas Fault and related faults, the Basin and Range province, and the Cascadia subduction zone. (2) Deformation at volcanic systems including the Cascade volcanic chain and restless calderas like Yellowstone and Long Valley. (3) The ubiquitous effects of groundwater migration on surface deformation. These studies provide insights into fundamental geologic processes (magma migration, the physics of earthquakes, etc.) as well as essential data for characterizing geologic hazards and resources. Finally, we discuss the development of new techniques and new research directions by WInSAR members.
