L'Aquila, Italy, April 6, 2009--Rendered by sophisticated radar instruments, the movement of the Earth during a devastating April 6 earthquake is seen from space in an image released April 15.

Using data from the Envisat and COSMO-SkyMed satellites, scientists were able to track within a few millimeters the actual movements of the ground before and after the L'Aquila quake, which killed at least 294 people and made 28,000 homeless.

Each rainbow band in the image shows about 2.8 centimeters' (about an inch's) movement of the Earth's surface.

The epicenter of the main quake is shown as a large green square. The center of each aftershock is shown as a small green square. A yellow line indicates areas that moved in unison when the main shock hit.
