Damage Proxy Map and Re-zoning MapA color map rendering of horizontal  ground deformation rendered as a GIS product for Tohoku-Oki, Japan earthquakeSAR and GPS shows areas of deformation and damage from M6.0 South Napa Earthquake

[1] The Damage Proxy Map (DPM) indicates centimeter scale change due to subsidence, inundation, or structure collapse allowing early assessment of the scale of damage. [2] Re-zoning map indicating where repair and rebuilding will be allowed.  This map is the product of many man-hours of effort to assess structures and the land that they were built on.

GPS coseismic displacements (colormap on land) and estimated area of fault slip (yellow contour off shore). The red star shows the epicentral location of the earthquake identified by seismic data. The question mark identifies the region where a subsequent large earthquake could occur. 

JPL-Caltech in collaboration with ASI/CIDOT responded to the M6.0 earthquake in California's Napa Valley by generating rapid GPS and SAR products, including radar based deformation and damage maps. More details and links to products can be found here.
