TEXT: Figure 1: Perspective view of the ground deformation due to the October 2011 magnitude 7.1 earthquake which struck the city of Van in Eastern Turkey. The rainbow colours show 10 cm contours of ground motion (up to 90 cm uplift in the mountains north of Van and 15 cm of subsidence under the city itself). This deformation is measured using the Italian X-band radar satellite COSMO-SkyMed. With this high resolution data, the precise location of the faults (black lines and white triangles) on which the earthquake occurred (yellow star at 15 km depth) can be found. This highlights which portions of the fault ruptured in the quake, and more importantly for examining future seismic hazard, which portions did not break – in this case the shallow sections of the fault (dashed line), nearer the city of Van.
