JPL-Caltech responded to Hurricane Maria by creating Damage Proxy Maps (DPMs) depicting areas in Puerto Rico and the Commonwealth of Dominica likely damaged by the Hurricane. More details can be found here.

JPL-Caltech produced a map of damage in and around Mexico City from the Sept. 19, 2017, magnitude 7.1 Raboso earthquake, based on ground and building surface changes detected by ESA satellites. Color variations from yellow to red indicate increasingly more significant ground surface change. More details can be found here.

JPL-Caltech created this Damage Proxy Map (DPM) depicting areas of Southwestern Florida that were likely damaged (red and yellow pixels) as a result of Hurricane Irma. More details can be found here.

JPL-Caltech responded to the M7.8 earthquake in Lamjung, Nepal by generating rapid GPS and SAR products. More details and links to products can be found here.

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.

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. 

[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.

Over 1200 permanent, geodetic GPS stations in the Japanese GEONET network recorded the motion of the Tohoku-Oki earthquake with 1-second resolution. This movie shows the displacements measured at each station. On the left, horizontal displacements are represented in magnitude by color, and in direction by an arrow at each GPS station. On the right, vertical displacement is represented by color.  The GEONET GPS data were provided to Caltech by GSI of Japan, and were analyzed at JPL using the GIPSY-OASIS software and JPL precise orbits.
