Quick Cut and Paste:
"The maps above show how the Earth moved in mid-September …..the amount of land motion is represented in shades from yellow to purple. Areas where the ground shifted the most (vertically, horizontally, or both) are represented in yellow, while areas with little change are represented in purple. …Interferograms can be used to estimate where the fault moved deep in the Earth and which areas have increased stress and higher likelihood of future earthquakes…"
