This is an unusual view of California's Napa Valley. It's not a photo, but an interferogram gernerated by using two radar images from the Sentinel-1A satellite.

The two round shapes visible in the central part of the image show how the ground moved during the quake. Deformation on the ground appear as rainbow-coloured patterns. The maximum deformation is more than 10 cm, and an area of about 30x30 km was affected significantly.

The image also shows that the fault slip continues further north than is obvious from a surface examination. Sharp lines in the interferogram show minor movements on other faults, such as the part of the West Napa Fault system that crosses Napa airport.
