Napa Valley earthquake,interferogram
Napa Valley earthquake. Synthetic aperture radar interferometry (InSAR) image of the earthquake that struck California's Napa Valley,USA,on 24th August 2014. InSAR is a technique where two or more satellite radar images acquired over the same area are combined to map surface topography and detect surface change. The two round shapes (upper centre) show how the ground moved during the quake. Deformation on the ground causes phase changes in radar signals that appear as rainbow-coloured patterns. Each colour cycle corresponds to a deformation of 28 mm. The maximum deformation is more than 10 cm,and an area of about 30x30 km was affected significantly. this was the largest quake to hit the area for 25 years. Image produced by combining two Sentinel-1A
