The Izmit Earthquake of 17 August 1999 in Turkey:

A Post-Seismic Analysis Using Optical and Radar Satellite Observations

As a result of a joint CNES/ESA/ESRIN study effort, interferometric fringes were computed from a pair of ERS-1 and ERS-2 scenes acquired on consecutive days (before and after the earthquake).
The fringes were superimposed on a SAR amplitude image (see below).
As a further step, the fringes were superimposed onto a Landsat 7 TM image, and an image product was generated, enabling a first damage assessment.
